wood saw blades production methods and their application of the

 Diamond saw blade production methods and their application of the effect of different production methods and application performance saw blade, the method currently used mainly to suppress the production of sintered diamond saw, a few blades produced using electroplating, sintering  GUSHI colde saw blade method common with cold pressed sintered , hot pressing and sintering welding three main ways. Saw another frequency welding welding and laser welding points.
  Diamond saw blade in a wide range of applications in developed countries, more mature technologies and standards, product and market segments have been, but with the further development of the technology of diamond saw blades, diamond saw applications will continue to expand, the market will continue to grow. Diamond saw domestic market has become the world's largest market, but aspects of the blade level, variety, range of applications and manufacturing technology there are still a wide gap with developed countries, regardless of technology or the market has much room for development, I hope GUSHI cutting disc for drill  the industry ambitious people to continue their efforts to eliminate the gap as soon as possible. In general, diamond saw blade contrast harsh working environment, the primary use of the product is sawing stone, widely used in large marble, granite, ceramic tiles and concrete finished cutting, the stone, the building materials industry and the primary widely used in the processing equipment.
 Cutting circular saw blades have manipulated lunch, effectiveness, good processing quality and other advantages. But noise than the large, rigid blade poor. Process prone cutting blade runout, deviation, resulting parallelism of the workpiece to be cut is poor. Saw Spindle GUSHI abrasive flap wheels  unbearable than the large sawing force, swinging the cutting process occurs without grams less than the cut-out line, although the added thickness of the blade can improve its rigidity, it is still difficult to guarantee parallel slices. In addition, adding the thickness of the blade not only adds costs and makes adding kerf width decreases the volume ratio.

a number of different categories of carbide saw blades

I. manufacturing process categories :
1 , sintered diamond saw blades : two of cold and hot sintering sintering , pressing and sintering .
2 , welding diamond saw : two stars frequency welding and  GUSHI abrasive grinding wheels laser welding , high frequency welding head through the medium of high temperature to melt and the substrate are welded together , the laser welding head by a high temperature laser beam in contact with the substrate forming a metallurgical bond edge fusion .
3 , electroplated diamond saw blade : It is attached to the head by an electroplating method powder on the substrate .
Second Appearance Category:
A continuous edge blade : Continuous serrated diamond saw, generally produced by sintering method , commonly used as a basis for bronze binder matrix material, cutting water to be added to ensure that the effect  GUSHI cutting discs of cutting and a laser head cutting kinds of useful gap .
2 , blade -type blade : serrated disconnected, cutting speed, suitable for dry and wet cutting methods.
3 , turbine -type blade : 1,2 combines the advantages of the previous two , the sawtooth -like uniform continuous presence turbo punch , improved cutting speed and increase service life.
Different materials selection of different types of  GUSHI dry cut blades diamond saw blades , different powder formulations for different material properties , the quality of materials and products , effects, and even the costs and benefits of the pass rate direct impact .

What impact concrete diamond blades cutting performance

We all know that the production is a special diamond saw, this blade is mainly used to cut about relatively hard material, but this blade can cut those specific substances it? Maybe we do not understand, specifically for you Introduction. Pick a good blade tips you know? Watching and small series. 1, you can see the saw blade diamond particles, if it is bad Saw blades are generally of poor quality, so it is very hard to use, or simply cut does not move. What impact blade cutting performance, you know? When conducting cutting blade, if exposed, would have an impact on the protruding cut, how  GUSHI diamond polishing tools to avoid this phenomenon?
When the particle size can be used during the cutting blade larger extent outcropping material will have a faster rate cut teams. Coarse particles are generally used to cut soft materials, and the smaller particle size was used for cutting hard materials. When making the cut, usually with increasing particle number, the number of particles per carat increases. So choosing the right number is a key tool to ensure performance.
2, the time of purchase, pay attention to the  GUSHI sds hammer drill bits texture of cutting, cutting should be very smooth, if there is a halt under the circumstances is a bad blade. 3, you can see through the head color is good or bad, the normal is a silvery white, if hair dark, indicating the knife is more and more impurities. You can use the diamond saw for aluminum, copper, magnesium and its alloys, tungsten carbide, wear resistance materials, wood, metal matrix composites can be cut. Directly affects the hardness of the blade to the cutting speed, and depth of progress. What is a diamond blade? If you are not a professional staff, we do not know, because we often say  GUSHI abrasive grinding wheels we choose a diamond with the now not the same as in the past, we do not know what is the diamond, but today found in all walks of life, Even in many areas, we will often encounter the shadow of the diamond, in which this special day, we sincerely wish you friends, happy New Year, life is happy happy!

Some simple narrative and the role of wood saw blades

Classified by material , the current domestic production of diamond saw

blade material matrix mainly 50Mn2V, 75Crl and 65Mn three materials , as

well as some low-end market with a 45 # steel. 45 # steel is ordinary

carbon steel , 65Mn spring steel is common , 75Crl high carbon alloy steel

. In comparison , 50Mn2V is a carbon steel , 50Mn2V fine grain size , high

thermal stability, high strength and toughness , fatigue resistance and

heat resistance. 50Mn2V saw the matrix material , with a number of complex

welding , long service life , the welding head blade easily deformed, easy

to repair after deformation , etc., as well as in the course of the

product so that the effect of high rigidity gradually , so 50Mn2V

materials are widely used in the processing and production of diamond saw

blade matrix . Classification according to specifications , the domestic

stone processing blade matrix size starting from ф200mm maximum of

ф3500mm ( foreign specifications for maximum saw blade towel 5000mm).

Which , dp200-600ram specifications mainly for trimming ( cutting edge )

processing semi-finished sheet ; ф650 above specifications is mainly used

for similar tombstone , grave stone columns and other thick (column )

forming sawing and for sawing blocks of cut ( board ) material processing.

Especially ф1600mm currently the most widely used blade matrix ф200 ~

600mm Specifications saw the matrix , due to the low technical content,

the technical and quality requirements are not high, only requires the

ability to use cutting edge on the line , the market tends to be

homogeneous product technology . Currently ф200 ~ 600mm blade matrix

specification hundreds of manufacturers , the market competition is mainly

price competition as the main means fierce competition in the industry ,

profit margins are low , some domestic enterprises do not intend to have

the strength to compete in this low-end market . Along with the increasing

emphasis on environmental protection , mining blocks scarcity of

resources, power resources in tight supply , rising  GUSHI diamond polishing tools stone enterprise

manufacturing costs, increased competition , a number of energy-saving ,

resource-based , environmentally friendly saw the matrix more and more

markets welcome , customer demand for varieties blade matrix there are

some new features: 1. Sheet , thin blade -based thin sheet , thin blade

substrate sheet , the thickness of the substrate primarily to distinguish

the ф1600mm substrate normal thickness 7.3mm, 6.5mm or  less in thickness

of the sheet is called substrate thickness 5.5 mm or less called ultrathin

sheet substrate . The use of thin , thin film substrate cutting blade

granite and marble slabs , can significantly improve efficiency and cut

blocks the yield , reduce power consumption , such as the GUSHI core bits for concrete  use of ultra-

thin thickness of 4.0mm. Ф1600mm matrix can improve cutting efficiency

over 10% , more than 20% reduction in power consumption , increase

utilization of 16% or more blocks . As the thin , ultra-thin diamond blade

matrix thin film thickness , diameter, large deformation during heat

treatment , and thus the degree of heat treatment on the plane and HRC

control is very important. And because the GUSHI concrete diamond blades  thickness of the thin end jump

to adjust the stress , comprising detecting great difficulties are caused

, in general , only by manual correction is difficult to achieve a good

level and detecting the effect .

blades matrix organization and properties of concrete diamond

Firstly, studied the sintering process and composition ratios on the mechanical properties of the matrix-free diamond. Using SEM, EDS for free diamond matrix organization observed and analyzed, revealing the variation matrix microstructure and mechanical performance. ANOVA using orthogonal experimental sintering process and carcass composition ratio is optimized. Then the carcass by adding different types of diamond, the effect of the mechanical properties of diamond on the carcass. Using SEM, EDS and the binding mode of binding conditions between diamond and matrix were observed and analyzed. Finally, Fujian 603 granite sawing objects, conduct real cut, copper-based detection of  GUSHI concrete saws different types of diamond saw blades wear prepared. Draw the following conclusions:
770 ℃ mechanical properties of the sintered matrix is ​​significantly higher than 690 ℃ of the carcass, carcass mechanical properties of thermal insulation 9min higher than 3min carcass. Matrix hardness is higher than with 8% WC carcass containing 4% WC, but the flexural strength and carcass containing 4% WC is roughly equal. Mechanical properties of the matrix containing 18% Ni is higher than 8% Ni containing carcass.
Flocculent white carcass organized by Cu, Sn, Fe, Ni for the four elements of the reinforcing phase is formed, the content of the tissue, the higher the mechanical properties of the carcass. With the improvement of the mechanical properties of the carcass, carcass fracture mode changes from brittle GUSHI concrete ring saw  fracture to the fracture toughness. Content of 8% WC, WC agglomeration occurs in a localized area. Analysis of variance optimization results show that: the best sintering process and carcass composition ratio of.
 After adding uncoated diamond, a sharp decline in the mechanical properties of the matrix. After adding titanium diamond matrix mechanical properties compared with uncoated diamond matrix adding a substantial increase. While adding titanium diamond and nanodiamond carcass compared with only adding GUSHI colde saw blade  titanium diamond matrix, the mechanical properties decreased slightly. Uncoated diamond exists at the interface with the carcass obvious gap for mechanical bond between the diamond and the carcass. Between diamond and titanium matrix tightly, no significant gap at the interface, EDS analysis showed that the chemical bonding between diamond and titanium matrix. Nanodiamond combination of adsorption in the form of the carcass, carcass nanodiamond adsorbed on the particle surface.

HSS blade radiator how chamfered concrete blades

Saw blade plate quality is very important. Because the blade to adjust the rotation, it has to pass the cutting force while keeping the stability of the work . Not only has excellent static blade geometry  GUSHI carbide saw blades and accuracy , and more importantly, its dynamic characteristics. When the cutting blade continuously , the heat generated sawtooth cutting saws will be transmitted to the temperature rise of saws , saws quality in this case also to maintain the accuracy of position , and the poor quality of the blade saw board warpage occurs , the impact of cutting accuracy. Dynamic stability is particularly important for sawing boards of several pieces into a fine blade set  GUSHI colde saw blade conditions for use . When multiple devices using a set piece saw blade instability , how can guarantee the quality of the longitudinal opening material . Saw blade plate and the head is an integral part of quality . Depending on the angle of the blade to grind the teeth , with left , center and right . There are left, right , middle . Tooth tooth width ( tooth density ) with the cut material size , wall thickness of the blade a great relationship, the more books tooth wall thickness is relatively dense , thick wall thickness should open GUSHI stone polishing pads  wide more, do not understand what you can always ask me, usually online.
        To be determined according to the thickness of the blade cutting the material , size open tooth , first , on the edge of the blade off the mouth of the well , and the second , on the grinding wheel grinding is good , and the third , chamfer should be uniform.

Some simple requirements of concrete diamond blades

The impact of different ways of diamond production dominate the range and performance of the blade. Diamond saw blade production methods related to its hegemony, at present, the production of diamond saw dying dying making way to stop the use of sintering methods, there are few ways plated blade production, there is a common way to stop cold sintering sintering, hot pressing and sintering sintering welding three kinds  GUSHI brick saws dying approach.
Diamond saw domestic market is the largest market in the world, but in the level of the blade, variety, scope and construction skills to dominate other aspects and there are still a large gap, therefore, whether it is on the market have the skills or its development. So, with the further development of technology, diamond saw blades will dominate the succession development, market growth will inherit. Dominate the range of diamond saw blade is very strewn in the construction of stone, glass, ceramics, crystals, gemstones, iron and other materials processing and houses, avenues, bridges, etc. in both utilization. Meanwhile, along with the diamond saw blade production GUSHI core bits for concrete  skills constantly updated and mature, are constantly expanding the range to dominate in many countries have throughout fortune grip. Diamond saw blade is widely used in stone cutting aspects, something major cutting hard points, so choose only one sharp and durable diamond saw blade is very important. Types of diamond saw blades are more sharp and durability is not the same, to choose a good diamond saw blades, diamond saw blades which we need to have a detailed understanding of, or else it is easy to be fooled insiders will in the past. And each person's identification methods are not the same, which we need to understand all aspects of the appearance of the head alone can not see, a lot of things that are hypocritical. High diamond saw blade is sharp knives door requires a diamond knife fast, usually are some hard cutting some things, so diamond saw blade life will be short, easily damaged. If you want to judge from the appearance of a sharp diamond blade is GUSHI dry core drill bits  high, is a more complicated issue, and the need to explore slowly. Some people are not very professional in the manufacture of diamond saw blades, when due to the technology is not very professional, it will directly affect the diamond saw blades sharp and highly durable. One method is generally the easiest to check whether the process is cutting the wrong time to listen to the voices of hybrid and low, high, and if a single voice, the quality of diamond saw blade is better.

concrete diamond blades cutting knowledge

1 , idle : in particular, a new base for the first time , the need to idle about 30 minutes, with a high temperature in summer season water needs to idle , which aims to further eliminate the matrix of the welding head, and enhance high-speed rotating blade held at state the intrinsic quality of memory.
  2 blocks of not less than 0.5m3, and placed securely , the bottom should be well- pad wood, solid plug is secured , blocks GUSHI abrasive grinding wheels  should be located symmetrically on the table to ensure that cars and blocks of solid bench , without shaking , trembling phenomenon .
  3 , according to the blocks of length, width , height adjustment limit switch , so that the blade lift and skip the trip in a reliable and effective range. Saw blade before sawing blocks should leave a maximum 10 ~ 20mm. After sawing, saw cut blocks should be left at the bottom of the 20-40mm, blade knife before walking around to run , should make all exit blocks kerf blade distance of not less than 150-200mm, to prevent the blade hit shortage material .
 4 , the test can be carried out after cutting blade idling stability , are not allowed to start the blade edge blade , cutting blades are not allowed to stop the rotation shall be stopped after the exit kerf contact with the blocks .
 5, after cutting blocks if there shaking discovery should immediately stop cutting the blocks to be firmly fixed in order to continue to work , cutting , and are not allowed to move in any blocks .
 6 , when the cutting blade found a significant slowdown or even a folder knife phenomenon , it may be belt slippage , compression nut loose or knife to eat too much depth , the cutting speed is too fast and other reasons, should be timely adjusted .
 7, the line speed should be processed stone hardness and wear resistance to adapt , it is recommended to select the next table line speed cutting different types of stone .
Tip: line speed is not high , an increase in cutting efficiency , reduced life of the blade .
      8 , feed rate , depending on the  GUSHI concrete diamond blades performance of the processing of materials for each material when there is a certain depth of cut is constant feed speed range , if the speed is too high, the diamond will accelerate wear and tear or even fall off , causing the blade consumption too fast, if the speed is too low , then they will make the process of self-sharpening blades can not be normal , so " blunt , slip " out cutting capacity . Under normal circumstances, when you cut the feed rate to slow , sawing should be uniform , typical for common materials when cutting depth is 20mm, recommended feed rate table below for your reference , when the thickness of the cutting speed can change cutting area (cm2/min) to conversion .
   Tip : The first three times before each feed or walking plates should be halved . Common materials blade feed speed unit : mm / mi
9 , the depth of cut stone for medium  GUSHI sanding discs hardness such as marble, limestone cut through at once , for hard and abrasive stone big as granite, sandstone should step cutting, saw cutting monolithic granite , eating knife depth is generally 10-20mm , depth of cut marble cutting tool 50-100mm, multi-chip -sided cutting hard granite , each cutting tool depth of 3-5mm, should be based on the hardness of the stone , using a saw blade and performance may be recommended following efficiency table for your reference. Common materials cutting efficiency Note: " 1 " indicates a low power finishing ; " 2" indicates a high -power roughing.
10 , the rotation direction of the blade in the same direction as the feed stone along the cutting , contrary to the reverse cutting , and when the reverse cutting , because an upward vertical component is formed of stone off potential, and therefore , the solid stone, in the same conditions Next , you should try to use smooth cutting. When using inverse cutting, cutting depth to be reduced , generally reduced to shun cutting 1/3-1/2 .

Alloy saw blade grinding at many factors can not be ignored when

1, the base body deformation, inconsistent thickness, a large hole tolerances, there is a problem when the substrate congenital defects, no matter the kind of device type, there are grinding errors. Substrate deformation big on two side angle bias, matrix hole large diametrical jump bias; substrate thickness is inconsistent after corner and edge front corner of bias, such as the existence of differential accumulation of work too, saw the quality and accuracy of severely affected .
 2, grinding teeth grinding effects on the structure of the alloy saw blade grinding machine structure and assembly that is good or bad, the market about two types of models: one is floating in  GUSHI core bits for concrete Germany Palmer type, class models with vertical grinding, the advantages of using hydraulic stepless all sports, all the feed system using V-rail and ball screw work, grinding or arm using the jog feed retraction rewind, adjust the center fuel tank clip, flexible support sheet Reliable, accurate positioning of teeth dial, automatic blade positioning center firmly centered, arbitrary angle adjustment, cooling rinse reasonable man-machine interface, high precision grinding, plain grinding machine design is reasonable; II, which is currently horizontal, such as Taiwan and Japan Machine type, mechanical transmission gears and mechanical gap exists dovetail slide accuracy, low clip smooth performance with film center adjustment difficult, pulling teeth institution or poor reliability, flat sides and around the corner is not a central grinding, producing large deviations , difficult to control the angle of mechanical wear disaster ensure accuracy.
 3, welding factor when welding alloys for moderate large deviations affect the precision grinding, grinding pressure while causing great pressure on the small side, rear corner also produce the above factors, the welding angle difference, inevitable human factors, all of When the grinding wheel, and other factors have an unavoidable impact. 4, wheel width on the quality and size, the choice of wheel running-gold films, pay attention to wheel size, granularity is too coarse grinding wheel produced traces wheel grinding selected fine grain size is less easy to plug, easy to burn knife. Wheel diameter and thickness is based alloy wheel width width or the length of each side of the tooth and non-alloy case may be, is not a front or corner after corner as wheel size available, can be any different tooth grinding, must be GUSHI carbide tipped saw blade  targeted to choose a suitable size wheel.
  5, grinding feed rate, alloy saw blade grinding entirely good or bad decision grinding feed rate, generally alloy saw blade feed rate 6 mm / s can not overspeed value, which should be in the 20 teeth per minute , exceeding speed is too large, will have serious knife harmartoma or burn alloy wheel produces concave surface affect the precision grinding waste into the grinding wheel 20 teeth per minute.
 6, grinding feed rate, the choice of wheel size on the amount of feed has a very important significance, suggested the use of general grinding wheel 180 # 240 # 240 # to choose the most, 280 #, 280 # to opt out 320 #, or to adjust feed rate. 7, grinding centers, all of the saw blade grinding and the substrate as the center, rather than the blade center, surface grinding center to get it out, horn, front corner with a processing center can not be sharpened a blade, grinding three blade center processes can not be ignored. Still careful observation side angle grinding alloy thickness, thickness change with different grinding center, regardless of how the alloy thickness, side grinding wheel centerline when welding position should be maintained in a straight line, otherwise the impact of cutting angle difference.
 8, dial tooth institutions can not be ignored, no matter how the structure and grinding, teeth dial coordinate system involves sharpening the accuracy of design quality, acupressure dial tooth tooth surface in a reasonable position in the transfer machines, but do not move but GUSHI abrasive grinding wheels  also its The key, when back teeth, jaw set aside should be flexible and reliable.
 9, Clips institutions: institutions clip stable and reliable labor solid, quality is the main part of the Brothers, the Brothers clip any organization can not have the slightest loosening, whether serious side grinding teeth bias control.
 10, grinding stroke, regardless of any part of the saw blade grinding, grinding, grinding stroke is very important, beyond the general requirements for wheel quit working 1 mm or 1 mm is appropriate, otherwise the impact on other teeth.
11 program options: Brothers General equipment coarse and fine grinding choice of three different programs, depending on the product requirements of the selection process when the final recommendations of the use of grinding mill rake angle.
 12, coolant grinding teeth grinding fluid that is good or bad decision given, when a large amount of cobalt tungsten grinding wheel diamond powder, not timely wheel washing and cleaning of the tool surface pores, resulting in surface grinding tool can not grind finish, there is not enough to cool it will burn alloys.

The main factors which affect the efficiency of the blade

First, the cutting parameters ( 1 ) Blade speed: in practical work , saw the line speed is equipment conditions , and restrictions were sawing blade quality stone before nature. From the best blade life and cutting efficiency , the linear velocity of the blade should be selected according to the different nature of the stone . When cutting granite , the blade may be within the selected line speed 25m ~ 35m / s range. For high quartz content and difficult cutting granite , remove the saw blade line speed limit is concrete diamond blades  appropriate. In the production of granite tiles, using a diamond saw blade smaller diameter , the line speed up to 35m / s.
( 2 ) cutting depth : the depth is involved in diamond cutting wear , effectively sawing , saw the forces and the nature of the important parameters are affected by sawing stone . In general , when a high line speed diamond saw blade should be selected for cutting of small depth , from the current technology , the cutting depth of the diamond can choose between 1mm ~ 10mm . Usually large diameter saw blade when cutting granite blocks , cutting depth can be controlled within 1mm ~ 2mm between the feed rate should be reduced at the same time . When a large diamond saw blade line speed , you should select a large depth of cut. But in performance and tool strength saw the extent permitted , should try to take a greater concentration of cutting cutting to improve cutting efficiency. When the surface of the processing requirements of a small depth of cut should be used .
( 3 ) Feed speed : Feed speed Jibei stone cutting feed rate . Its size affect the rate of cutting , the blade and the cutting force by the heat dissipation area . Its value should be based on the nature of the stone sawing selected . In general, the sawing softer stone, such as marble, may be appropriate to increase the feed rate, if the feed rate is too low , more conducive to improving cutting rates. Sawing fine structure , relatively homogeneous granite , may be appropriate to increase the feed rate, if the feed rate is too low , diamond blade easily be polished . But while sawing UNEVEN coarse structure of granite , feed rate should be reduced , otherwise it will cause the blade vibration resulting in reduced fragmentation of diamond cutting rates. Granite cutting feed rate is generally within the range of the selected 9m ~ 12m/min .
 Second, other factors a ) diamond size : diamond particle size in the common range of 30 /35 to 60/ 80. The more hard rock , should be selected with a finer granularity. Because under the same pressure conditions , the more detailed the more diamond sharp cut in favor of  tile cutting blades hard rock . Further , the general requirements of a large-diameter blade cutting efficiency high , the particle size should be selected with a coarser , such as 30 /40 , 40/ 50 ; lower small-diameter blade cutting efficiency requires a smooth cross-section of rock cutting , should to a smaller particle size , such as 50 /60 , 60/ 80.
( 2 ) Segment concentration: the so-called diamond concentration , refers to the density distribution in the working layer of diamond carcass ( ie, the weight of the diamond contained within the unit area ) . "Norms " provides the carcass per cubic centimeter work containing 4.4 kt diamond , its concentration was 100%, with 3.3 karats of diamonds , its concentration was 75%. Represents the volume concentration of the volume occupied by the number of diamond agglomerates , and that, where a concentration of 1 /4 volume of the total volume of diamond is 100 %. Increasing the concentration of diamond is expected to prolong the life of the blade , i.e., reduced because of the increased average concentration of each piece of diamond cutting forces suffered . However, increasing the depth of the blade will increase the cost , so  cutting discs there is a concentration of the most economical and the concentration increases with the shear rate increases VS .
( 3 ) the hardness of head binders : In general , the higher the hardness of the binder , the stronger its wear resistance . Thus, when a large rock cutting abrasive , hardness should be high binding agent ; when cutting soft rock material , the hardness of the binding agent should be low ; when sawing hard and abrasive rock large , the hardness of the binding agent should be moderate .
( 4 ) force effects, temperature effects and grinding damage : Stone cutting blade in the process , will be alternating load centrifugal force , cutting power, cutting fever. As the force and temperature effects caused by diamond saw blade worn donate damage .

During operation of the concrete coring machine

 During operation concrete coring machine , mainly preparation, installation , drilling, drill , final hole five steps.
Preparation 1 , the use of pre-
( 1 ) adding 93 # unleaded gasoline and high oil, how much oil can be added to prevail based on the dipstick mark.
( 2 ) in the column filled with oil and turn the handle and feed the output shaft , check the feed and rotary is flexible and reliable.
( 3 ) ready for water.
( 4) Check all parts of the screw is loose.
2, the installation
Drill holes later on , the three  concrete saw blades walking round lifting , so the base fell to the ground. Hit the hole and concrete strength is not high , then you can rely on its own weight rig rig fixed , if playing a larger aperture , the rig can not hold their own weight when the rig can place heavy objects ( such as sand bags on the chassis, iron , concrete blocks , etc. ) fixed or play two bolts plus bar ( such as channel , etc. ) to secure the rig , rig securely fixed to not shake , otherwise not normal drilling operations .
3 , opening
After doing these jobs , job openings can , put on the drill , the starting gasoline engine (see gasoline user manual ) of the inlet pipe into the bucket, the bucket to mention higher pump position, and  grinding cup wheels then pinching the water suction gas -hsiang pumps, water pumps , Sheung Shui, the bucket on the ground level . Throttle to maximum and began to jiggle the handle into the drill slowly touch the ground. Opening Tip: after the first water drilling, feed slowly, WOB small. Prohibited anhydrous job , it would burn the drill and seal .
4 , drill
When 2-3 mm deep hole drilling , the drilling can be turned into a normal , appropriate at this time to increase the  feed pressure , normal drilling tips : feed pressure should be moderate , to maintain uniformity , crude steel to encounter to reduce the intake pressure . To do listen second look , whether listening to the sound of the machine  diamond cutting tools properly, to see whether the return orifice ( risk ) of water.
5 , final hole
After reaching a depth taken , you can stop drilling . Stop drilling requirements are: first turn off the water after the machine when if deep , can not immediately provide drilling and without water , while punching with water for some time, aimed at the hole in the rock powder rinse to prevent rock powder precipitation resulted in burying cause coring difficulties.

Electroplated diamond cutting discs role

Resin bond diamond wheel is mainly used for parallel carbide measuring tools, cutting tools , molds and other surface grinding , cylindrical grinding , bore grinding, grinding and also used as a cut man bronze molding bonded diamond grinding wheel is mainly used for hard brittle non-metallic materials , such as glass , ceramics, ferrites , precious stones and other cylindrical and planar processing , but also for the electrolytic grinding carbide products .

When using resin knife, spindle speed should be within 16000-40000r/min , the Heat do not exceed the specified  concrete grinding wheel maximum speed , otherwise the blade will automatically body . To choose high-power spindle speed spindle speed in determining when another speeding , they should also consider the material hardness , soft material dicing cut high spindle speed gestures hard materials, low -cut plan than the spindle speed , and cut into thick material planning .

during the grinding the grinding characteristics of

1 deformation complex grinding process to produce chips stacked like squeeze crack.(2) the grinding process, the grinding wheel adhesion severe adhesion loss can lead to wheel abrasive material diamond core drills  crushing and shedding.3 grinding force, grinding temperature is high, the normal force per unit width reaches 13N/mm about tangential grinding force per unit width reaches 9N/mm so. Grinding temperature reaches 650 degrees.4 high chemical activity, if titanium silicon carbide grinding wheel when the grinding action of heat, the silicon and oxygen in the air react to produce silicon oxide, the release  concrete pads of heat, so that the surface layer by layer abrasive erosion, wheel causes oxidation wear, and that react with the titanium carbide, titanium carbide, resulting in the spread of wheel wear.he main difference is the type of binding agent: resin bonded diamond grinding wheel mainly phenolic resin and a small amount of metal powder as a binder, and  tct blades electroplated diamond grinding wheel is a method by electrodeposition of nickel-cobalt alloy is deposited on the metal substrate surface and fixed to a diamond abrasive wheel production process.grinding force, grinding temperature is high, the normal force per unit width reaches 13N/mm about tangential grinding force per unit width reaches 9N/mm so. Grinding temperature reaches 650 degrees.

ost-effective way to improve the grinding wheel

the best way to improve the cost of: grinding the core of the sheet is not part of the cutting action in a poor quality and low price instead of a secondary abrasive, abrasive cutting quality full performance, lower manufacturing costs.Sheet wheel performance depends largely on the merits of using abrasive quality, good quality abrasives, grinding wheels, high grade, and in the more expensive price. As the domestic high-grade bauxite  green concrete blades resource depletion, a variety of raw materials and coal prices in mid-rise, coupled with energy saving the environment forced shut down, corundum prices are rising fast, from time to time will be in short supply. How rational use abrasives, improve market competitiveness, is the most important enterprises grinding technology considerations.Best approach is to not participate in the core sheet wheel portion of the cutting action of poor quality with low prices instead of secondary abrasive, abrasive cutting quality full performance, lower manufacturing costs. This approach resin bolts and large diameter cylindrical grinding wheel resin grinding wheel has been widely used. For thin grinding wheel, since the intermediate screening, the  polishing pads for granite bottom and the top to separate the feed, if the external and the core are stepwise feeding, in the process to implement quite difficult, is still only vision in the future, if successful, cost reduction, profit improvement , on sheet wheel manufacturing is undoubtedly a far-reaching "technological revolution."Compare prices now wear suitable strategy for various consumer groups, in accordance with abrasive made of different grades of abrasive products, the best abrasive used in most need sheet wheel, avoiding production of low-grade abrasive grinding wheels with high-grade, as far as possible best use, cost-effective in improving the premise, a great effort for each grade of the product have done "extreme."High-grade sheet wheel stable, targeted, reproducible production has generally adopted a sand, special cup grinding wheels  products and even to use zirconium corundum, calcined alumina abrasive and post-processing. The market is dominated by imported products, most cost-effective production of high sheet is not high, not discrimination, targeted not strong, still need further research and development efforts.If you use an ordinary sheet wheel sand, cost is very low, almost no profit, now commonly used two sand instead. The so-called two sand, refers to those standards is not abrasive, aluminum oxide content of about 80% of corundum, good quality two sands, also known as a second, different origin, different batches of two sand quality fluctuation range large. Sand production sheet wheel with two main problems is the wheel performance is unstable, different batches of the same recipe abrasives, grinding wheels produced poor reproducibility, good times and bad

Trimming cutter grinding wheel surface generally

removed from blunt or abrasive ceramic particles in an effort to reduce the grinding temperature and improving the  Plate Compactor surface roughness and improve the grinding wheel small tolerance machined workpiece capacity. Trimming tool is also used for finishing grinding wheel. In the past, most of the trimming and finishing operations are fixed into the rotating grinding wheel dressing tool, this tool is often trimmed with made of single-crystal diamond or PCD.Today, many high productivity CNC grinding operation using rotating or sharp dresser dressing roller. When  floor polisher pads the wheel side of the workpiece, its other side on the same time are continuously refreshed. CNC rotary trimmer can accommodate more than 100 same diamond, these small diamond pieces mounted on the outside diameter of the dresser, in the grinding wheel to generate a unique shape.Laser cutting, independent CVD diamond dressing tools give users and  14 inch saw blade producers many unique advantages. CVD diamond structure can be designed and manufactured to have a higher fracture toughness and strength, so as to optimize tool life and dimensional stability trimming purposes.Because CVD diamond is cut into thin slices, which can minimize or eliminate the problems associated with single-crystal diamond, such as natural diamond shape constraints and the inherent variability and so on. Finally, CVD diamond material can be manufactured into high aspect ratio (eg: 8mm × 1mm × 1mm), CVD diamond dressing tools mounted on a cost-effective, extend life and improve the efficiency dressing.

great potential diamond coated tools

 Diamond from carbon atoms, in a unique arrangement of the crystal orientation, so as to possess unique physical  hss drill bits properties. 9,000 to 10,000 Vickers hardness, the hardness is almost non-crystalline diamond crystals DLC coating (DLC) twice.Non-crystalline diamond or DLC coating said, is the physical vapor deposition (PVD) process of coating a carbon thin film. These films are coated with chemical vapor deposition process over the thin diamond film.They do not have crystal structure, life is generally CVD diamond coated tools 10-15%The tool coated with a metal sintered polycrystalline diamond (PCD) forming a diamond tip is different crystal CVD diamond coatings can make the entire surface of the tool (including those with complex geometry concrete vibrator  of the tool included) protected by the superhard material. Such unique geometry can be coated with the chemical vapor deposition of diamond-coated tools with polycrystalline diamond tools more significant than the advantages, making the latter's grinding cost is very high.With metal - nitride PVD coatings, such as titanium aluminum nitride (TiAlN), the micro-hardness of diamond crystals only 1/3.CVD diamond coated drill bits with polycrystalline diamond tip drill bit has the following benefits compared to the carbon fiber drilling application has been fully demonstrated, and the hole diamond wire saw  costs reduced by 70% or more. Chemical vapor deposition of multilayer diamond drill burrs and delamination occurs before the composite material can be processed through holes 300 and PCD tip drill but can only process 150 through hole.Crystal diamond on a hot filament chemical vapor deposition process to form, this process time of 20-40 hours. The temperature employed in the process of 1,500 ° F (815.5 ℃) can be prevented unless something other than carbide coated, and the precise pretreatment process requires the use of a cemented carbide 6% level to achieve the best adhesion.Without pretreatment, diamond and carburized almost no chemical bond between the cemented carbide. However, roughly diamond carbide can be embedded in the surface of cemented carbide and diamond by the action of the mechanical interlocking adhered to the surface.

Wear alloy saw major factor

A phase change alloy blades wear friction in certain high-speed cutting process, substrate or material at temperatures above the phase transition temperature , makes the alloy saw blade with accelerated wear , and thus lose cutting ability . Such as high speed steels 500-600 °, ordinary  masonry drill bits steel 100 °, alloy steels 300-350 °, 65 manganese steel 200 ° temperature inside will result in the matrix phase transitions.
2 , the alloy microstructure in the welding temperature or other factors in the destruction of high -density ultra- fine particles in the welding alloy cold and hot temperatures , or high temperature , resulting in thicker alloy crystal , alloy cracking, deformation of the matrix alloy strength reduction and abrasion resistance .
3 , tool wear, cutting angle design and material discrepancies due to different hardness and various types of plastic stone drill bits materials not targeted under the appropriate choice of alloy , and no matter according to the hardness of the cutting dry cutting angle of each side effect which reduces tool life .
4 , the oxidation of the alloy blade wear oxidation wear at 800 ° C or higher friction temperature, oxygen in the air and alloys of cobalt , tungsten carbide, titanium, tool wear due to oxidation occurs .
5, the impact of technology and precision grinding wear, alloy circular saw blades are precision cutting tools, any main and sub- edge blade with tape, face cutting straight face , or radial cutting rather than a cutting line, each one formed alloy cutting point or depth , and many other factors that reduce their effectiveness .
6 , diffusion wear diffusion is cutting discs a chemical wear, diffusion wear is at a high cutting tool and the workpiece between the mutual diffusion of alloying elements , the tool material physical and mechanical properties of reduced lead increased tool wear . Carbide, titanium carbide increased in the tantalum carbide or other additives can be added to improve the matrix alloy and the temperature of diffusion and thus improve tool wear resistance and heat resistance.
7 , adhesive wear in the cutting of plastic material , the cutting and the rake face after the cutting work viscosity, the tool surface or partially lower strength adhesive particles or the workpiece to be cut so that the tool with grinding brush wear.
8 , improper maintenance or improper operation caused by wear and tear , each cutting equipment, cutting feed rate is not the same , while the alloy saw blade is designed according to different cutting material various angles , with inappropriate will reduce its effectiveness.

Large saw blade stone mining application

At present, China mining have the following main ways: blasting, flame cutting method, expansive law. Its mining methods sds drill bit   ordinary deposit with low labor productivity, finished product rate, serious waste of resources, poor security shortcomings. In recent years, some companies use diamond wire saws, chain saws, etc. diamond mining, has yielded good results, but the equipment into large, higher mining costs, is still not large-scale use. How to improve the quality and efficiency of stone mining to minimize environmental damage, reduce labor intensity, and has become an urgent need to mine stone blocks to solve the problem.Second, cutting principlesFor the  masonry drill bits above, our scientific and technological personnel to sheet cutting mechanism cleverly used in mining, and achieved good results. The basic principle is: the table and laying mines track, driven by the host very large diamond saw blades (Ф2000 ~ 3500mm) high-speed rotation, rail-cutting. Because the way into a small, high efficiency, safety, environmental protection, energy and mining low cost, widely favored by the mining companies.Third, the technical requirements
In addition to asking Saw this mining method to have a good accuracy, the large diamond saw blade specifications, quality and cutting blades  other key to this technology. As we all know, the decision by the mesh size of the mining blocks blade specification decisions. Currently, the market requires sheet width up to 1.5m or so. Therefore, a matching diamond saw blade specifications must reach Ф3500 over the same time, field work environments such as mining operations and flatness, cooling conveyor and other relatively sheet cutting, conditions even worse. Therefore, the blade base body made more stringent manufacturing requirements.

refurbished marble polishing process according polished stone texture

Stone after long years of use as well as its natural weathering, coupled with artificial improper care can easily lead to its natural color and brightness disappears, it makes your head can wet tile saw  not bear to see; redecoration costs are too high, too long. Marble renovation process is in a very short period of time the use of chemical and physical role in the original basis through the machine grinding, polishing, restoring it to its original brightness, natural color, brightness hundred percent, both economic and time-saving, life of more than five years.
Process
Tools: Stone refurbished machine, terrazzo machine, washing machine, marble polishing machine, vacuum suction machine, diamond disc 6 groups, red mat, white mat, special scouring pad
Using Pharmacy: stone abrasives , stone lightening agent, stone protective agent
According to the different levels of  cutting wheels damage to marble, with refurbished machines with different diamond discs for grinding, must comply with the texture of stone lines operate until the stone surface is smooth and uniform color; polished with an abrasive pad with penetration and dried up; using credit agent be polished with mat until dry, and finally sprayed protective agent polished until the brightness recovery ever. The renovated stone surface of different materials according to their own maximum brightness of up to 120 degrees.
Marble is the main mineral component is a variety of calcite, dolomite or serpentine. Marble durability and relatively low luminosity than granite. Therefore, the possibility of refurbishment, renovation of difficulty, cost is relatively low. The key is to improve the tile cutting blades  renovation of flatness, brightness, hardness and anti-seepage treatment. Machines, abrasives, operation, these three should combine organic, will damage the stone surface using mild, moderate, deep renovation.
