Indicators will be secure in the GUSHI concrete diamond blades transition layer is equal to the substrate adjacent to the Department of the diamond layer

Indicators will be secure in the transition layer is equal to the substrate adjacent to the Department of the diamond layer . Our base for the abrasive layer convergence , and in the use with flange firmlyabrasive grinding wheels held on the grinding machine spindle. Suri outside environment as more rounded shape . There is not a diamond wheel diamond production from. It may be divided into three layers , i.e. task layer , substrate buffer layer . As long as the task layer is called the diamond layer , the abrasive agent and filler compact form seems like a diamond determines its inability to do4 inch saw blades tough . The buffer layer and the substrate are non-diamond layer . Even as a diamond wheel roots sand arrived with its most empty thinking is to see the consistent use of abrasive materials . Its primary organs are made of metal powder, resin powder , ceramic and metal plating as liaison agent. How the diamond wheel three disjointed comprehensive alone. If the corporate team as it tastes good Qianan three choices of diamond grinding wheel diamond place.

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.

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.

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!

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.

On the next to improve the quality of high-quality concrete diamond blades technical solutions

Aligned with the status quo, the end of Britain repeatedly theory, a set of production efficiency, quality diamond saw blade skills programs available.
1, the choice of the production function stable, coarse particles, heat stable and good (ti and tfi straight near to) the high-strength diamond. What is essentially a diamond diamond carcass must process conditions under fixed on the operating base, mainly by diamond grinding agent, not the same as cutting role to process the stone. Thus, the original data (diamond) quality, particle size and concentration on the diamond thing has a decisive role.
 2, although charcoal powder into a strong element of progress diamond control force. In the processing of diamond saw blades, diamond blade carcass if there is a good operating force, diamond blade is a distinguished, not prematurely fall, when cut sharp, high power. Usually top end of the outer plating layer of diamond strong carbon compound, the constituent metal elements, such as plating, titanium, chromium, nickel, tungsten, etc., in order to progress with the matrix powder of diamond bonded and sintered at high temperature to avoid favor diamond After oxidation and graphitization; other top end of the carcass can also be powder, carbon powder of a few strong increase of elements, such as: molybdenum, chromium, tungsten powder. Because this type of powder gold, moisture resistance and better affinity diamond, diamond sintering metal carcass appearance constitute carbide alloys, diamond and matrix metal in favor of chemical bonding and Metallurgy contact, and greatly improved the carcass diamond manipulation force.
  3, to improve the diamond particle size ratio. Traditional ratio, the sharp tip to more, spend more coarse diamond, and vice versa with a fine diamond. Of course yes, but it has been less than optimal operating power. Because the hardness and elastic modulus of diamond art high temperature GUSHI abrasive grinding wheels  sintering is difficult when the onset of plastic deformation. Selected ratio, before sintering progress bulk density of the diamond particles on the progress of the tool wear ratio is advantageous. Britain at the end repeated test results usually head coarse, coarse, fine diamond particles composed of three kinds, the optimal granularity share 1:0.0227:0.071. 4, the choice of ultra-fine powder and pre-alloyed powders. Ultrafine powder sintering temperature dropped in favor of progressive matrix hardness. The pre-alloy powder, the top end of the three-dimensional mixing, greatly reducing the touching moments powder and air, to avoid premature loss of the low melting point metal segregation and contribute to the progress of the strength of sintered products, increase the operating force of the diamond.
 5, increasing the excess of rare earth  GUSHI concrete ring saw elements (such as lanthanum, cerium, etc.) in a matrix powder. Contact agent can significantly decrease the wear features progressive diamond saw blade to cut the power.
  6, a selection of cold thermal sintering process, maintain vacuum sintering atmosphere. Top end of the cold tip after sintering is reflected in a very sharp cutting process, many progressive power production while maintaining a vacuum sintering atmosphere to avoid oxidation of the powder, activated sintering, both the head progress function and prolong the graphite mold The number of longevity, but also to decrease production costs.
  7, the correct welding technology, nowadays Diamond Park saw both use high-frequency welding machines to weld, the  GUSHI colde saw blade welding head is easy to show the second "burn" and head off appearance. Not only unsafe, and the impact of production, and therefore should be used in high-strength, permeability good silver solder pieces for welding production.

Some applications use glass blades

 It should be noted that the pre-alloy powder has been laser welded diamond saw with wood powder material of the buffer layer growth of the target object of [17,23], because: the pre-atomized powder alloy powder manufacturing process used to ensure Average ingredients conducive compressive and flexural strength improved sintering products; may reduce the brick saws  sintering temperature and shorter sintering time, especially the fate of more obvious when using ultrafine or nano pre-alloy powder; favor of pre-alloyed elements diversification and reduce the amount of cobalt. Built with reinforced concrete for large-building, with a diamond wire saw cutting orderly enumeration is very convenient, and did not happen very big noise and dust.
  2 welding process laser welding diamond saw blade woodworking are differences thick welding dissimilar materials, the impact of the tile cutter  identity of many of its welding quality, collecting the preparation before welding, laser beam quality, laser power, welding speed, focal position of the laser beam offset , the angle of incidence of the laser beam, care of the gas flow, and now in this regard should be said that the fighting strength mature.
 But the transition layer can not contain low melting point metals such as tin and other elements, these elements easily because of evaporation and vaporization stomata occur, but can intervene from a small amount of solid solution strengthening, adding to abrasion and cut and weld concrete polishing pads  porosity dip  r mn elements. Thus, in the process of these spaces can easily be metal shavings clogging the worst is leading to "burn" the work and become waste. , In the beginning of cutting and curb cutting, do not feed too fast to avoid broken teeth and damaged.

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 .

In the selection of carbide saw blades which should be noted when

Contains tooth carbide saw blades, angle, number of teeth, blade thickness, blade diameter, carbide, etc. Most types of parameters that determine the processing capacity of the saw blade and cutting. When you select the correct selection of the blade to blade parameters based on  GUSHI diamond discs need. Tooth, tooth commonly have flat teeth, Dou tooth, trapezoidal tooth, inverted trapezoidal tooth (Figure 1). Flat teeth the most widely used, mainly for ordinary wood sawing, this tooth is relatively simple, rough kerf, slotting process operating level during tooth formation can bottom. Dou teeth sawing kerf quality is better for cutting all kinds of wood-based panels, plywood. Trapezoidal tooth suitable sawing plywood, fire board, obtain higher cutting quality. Inverted trapezoidal tooth saw blade used in the bottom slot. Zigzag zigzag angle is in the cutting position. Serrated cutting angle affects the performance results. Greatest impact is on the cutting rake angle γ, the angle α, wedge angle β. Rake angle γ is serrated cutting edge angle, the greater the cutting rake angle more brisk, rake angle generally between 10-15 °. After the angle is the angle between the machined surface of the sawtooth between its role is to prevent the serrations machined friction surface, the smaller the angle the greater the friction, the more smooth the processing products. After the general value of carbide saw blade angle 15 °. Wedge angle is derived from the anterior GUSHI abrasive flap wheels  horn and posterior horn out. But the wedge angle is not too small, it plays a role in keeping the teeth, according to strength, heat resistance, durability degrees. The rake angle γ, the angle α, the wedge angle β of the three equals 90 °. Jagged teeth, teeth more generally, the more the cutting edge per unit time, the better the cutting performance, but required more and more carbide cutting teeth number, the price of the blade is high, but too dense serrated , the chip between the teeth becomes smaller, the heat is easy to cause the blade; sawtooth excessive addition, when the feed amount of mismatch, then cut per tooth is small, the friction will increase with the workpiece edge, the life impact of the blade . Typically tooth pitch 15-25mm, should be selected based on a reasonable number of teeth sawing material. The thickness of GUSHI sds hammer drill bits  the blade from the saw blade in theory, we hope the thinner the better, is actually a kerf consumption. Materials and manufacturing processes carbide saw blade sawing board determines the thickness of the blade. To consider when selecting blade thickness from work and the stability of the blade sawing materials. Diameter and thickness of the blade used for cutting and sawing equipment related artifacts. Blade diameter is small, the cutting speed is relatively low; blade diameter saw blade and cutting equipment requirements will be higher, while cutting efficiency is high.

How to identify and saw the matrix do good piece burr cut big reason

Saw the matrix to identify how to do: Use a permanent marker to make the hole in the middle of the blade near the logo, after the device has a flange on the blocked will not be erased; using laser GUSHI core bits for concrete  marking, such as fast peerless blade; most good is pneumatic marking. Hot rolled plate (plate oil must deformation) material production, saw tooth after punching hole and made a good fly how to remove the burr hole around the edges and tooth equipment and the way equipment with the center point of grinding (also called the hole grinder) it? Using simple equipment on bench below to make a base fixed. Tooth points glitches, buy a serrated grinding machine or by hand with a look. Why aluminum blade cut piece burr is always king, get a new blade also has a glitch, there is some kerf side has no burr burr side?
  There are two effects:
  Material: Soft hardness usually aluminum sawing down after glitches obvious, so you aluminum materials and state is not too soft
 Sawing question: blade and cutting speed, cutting equipment usually used between 5000-6000 rpm, the problem is generally GISHI concrete diamond blades  estimated that the blade is a 9-inch alloy saw Bosch ,60-70 yuan a piece, very durable Gold Fields is also available. Of course, if the condition can also buy Bosch circular saws, one to be in the vicinity of 1,000 yuan, 2100kw Bosch's encroachment up pretty good, at least much better than Rui Qi. Of course, you can also choose metal band sawing machine sawing advantage of small incision, less waste, while the cut is not as smooth, the disadvantage is the high price band, a small range of processing.

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 .

Diamond grinding machine defect inspection

To our knowledge diamond grinder before installation must undergo a rigorous inspection , cracks and other defects in the diamond grinding machine is definitely not allowed to install and use . Please read on.
( 1 ) diamond grinding machine tag checks. Diamond grinder no markings or unclear, unable to verify , confirm the characteristics of a diamond diamond grinding machine grinding machine , regardless of whether there is defective , are not available ; ( 2 ) diamond grinding machine defect inspection . Its inspection methods are visual and carbide saw blades  sound checks : ① direct visual inspection with the naked eye or with other appliances inspect the diamond surface grinder for cracks or damage and other defects ;
② sound check , also known as percussion test , mainly for internal defects in diamond grinders , inspection method is to use small wooden hammer percussion diamond grinder . Normal diamond grinders crisp sound, sound dull , hoarse , indicating that there are problems ; ( 3 ) the strength of diamond rotary grinder test. The same number of diamond grinding machine models should be turning intensity random testing without strength test batch of diamond grinding machine installation is prohibited .
How to make a diamond diamond grinding wheel wear slower in our daily lives has become so widespread , that how can you slow diamond grinding wheel wear often , you know? If you do not know to  metal grinding wheel give with Xiaobian look at it .
Select the diamond grinding wheel hardness general principle is : the processing of soft metal , in order not to make premature loss of abrasive , then use a hard wheel. Wear resistance and long life . Diamond grinding wheel ratio up to 3500-5500 , a hundred times higher than normal corundum grinding wheel , 3-5 times higher than ordinary diamond wheel . When processing hard metal , in order to make timely blunt grit off, thereby exposing new abrasive grains with sharp edges ( ie, self-sharpening ) , use a soft wheel. Or because the soft material in the grinding wheel abrasive wear is slow work , without departing too early ; latter is because the grinding of hard materials , abrasive wear of the grinding wheel work faster, require faster updated. High  tile cutting blades efficiency, good overall economic efficiency . Grinding sharp, small grinding force , diamond grinding wheel dressing cycle length , less the amount of dressing , long replacement time ; long life cycle, grinding ratio , getting a better economy, use good shape retention , without regular replace the wheel and wheel dressing , saving time and improving working conditions conducive to machining operations .

How to achieve the best performance multi-chip saw blade alloy

In order to play a round alloy saw its best performance , must strictly observe the following points: ( 1 ) wire tapping machine should have a good performance, no vibration. ( 2 ) the size of France blue plate diameter should be consistent about French blue plate surface in contact with the saw blade saw blade diameter of 1/ 3 ( 3 ) should be perpendicular to diamond bandsaw blades  the centerline of the hole . ( 4 ) at both ends of the gasket surface should be parallel and perpendicular to the centerline of the hole .
( 5 ) Saw spindle runout straightness and definitely not super bad, spindle diameter does not exceed the tolerance H7 (6) multi-chip saw blade clean before installing the first , if the blade body sticky with resin , thinner wiping required go, and saw the body is coated with a protective layer , it can be wiped off with hot water , avoid using corrosive solvents. ( 7 ) If the blade has insensitive , should immediately grinding , taking care to keep the original serrated cutting angle . ( 8 ) when grinding not only to choose a suitable diamond grinding wheel, but also the use of coolant. ( 9 ) blade reamer recommends no more than 20 mm of the original hole , otherwise it will lead to loss of photos , then the effect will be affected by the cutting blade . ( 10 ) Each installation must ensure law and blue plate washer clean and smooth. ( 11 ) when the repair after grinding angle and saw the body must be careful not to manual operation, will result in jagged fragments and saw the body imbalances. ( 12 ) Gangsaw installation, careful iron rack and need feeding chamber was the same level. ( 13 ) before cutting blade to check whether the tightening has been installed , to prevent slipping on the  masonry drill bits shaft displacement and the blade . 1 blade If not used immediately , it should be flat or use the hole to hang it up, can not be stacked on other items or foot flat blade cutter , and pay attention to moisture, anti- corrosion. (2) When the blade is no longer sharp cutting surface roughness , it must promptly re- grinding. Grinding can not change the original angle , and destruction balancing . 3 inner diameter of the blade correction , the positioning hole machining , etc., must be performed by the manufacturer . If the process is bad, will affect the product effect, and potentially dangerous , reaming should not be over the original aperture 20mm, so as not to affect the stress balance. Choose alloy wheels 4 .
1 ) resin bonded diamond grinding wheel bond strength is weak, and therefore capable of self-sharpening grinding is good, clogging, high grinding efficiency, low grinding force , grinding temperature is low , the disadvantage is poor wear resistance, abrasive wear and tear , it is not suitable for heavy duty grinding.
2 ) vitrified diamond grinding wheel wear resistance and superior binding capacity of the resin binder, cutting sharp, high-alloy blade grinding efficiency , easy fever and congestion, less thermal expansion , easy to control the accuracy and disadvantages coarse grinding surface , higher cost .
3 ) high metal -bonded diamond grinding wheel bond strength , wear resistance, low wear, long life, low grinding costs , can withstand a greater load, but sharp poor, easy to plug .
4 ) There grit size wheel jam circular blades  and cutting the amount of a certain influence , coarse sand and fine sand compared , large depth of cut increases abrasive wear of the cutting edge , and vice versa wheel easy to plug .
5 ) Wheel hardness greater impact on clogging , high hardness, high thermal conductivity wheel is not conducive to the surface of the heat , but help to improve the machining accuracy and durability.
6 ) Wheel concentration choice is an important feature, its grinding efficiency and processing costs have a significant impact , affecting the efficiency of the concentration is too low , whereas abrasive easy to fall off , but the best combination of agent concentration range

Matters related to the use of the saw blade

Precautions blade using:
 1 Keep alloy saw hanging vertically on the drying rack, be sure to avoid damp places, do not alloy blade flat on the floor or shelf, flat lead alloy blade deformation.
2 When using, do not exceed the  abrasive flap wheels specified maximum speed. After the speed of calculation is attached for reference.

ultra-high speed grinding occupy undisputed dominance

1, the plating process is simple, easy to manufacture, less investment;
2, easy to use, no dressing;3, single-layer structure determines it can reach very high operating speed, the stone drill bits  current foreign countries have been as high as 250 ~ 300m / s; 4, although only a single layer of diamond, but there is still sufficient lifetime; 5, for high precision roller wheels, electroplated unique manufacturing method.Because of these advantages, electroplated grinding wheel speed, ultra-high speed grinding occupy undisputed dominance. Electroplated diamond grinding wheel defects exist: the coating and the substrate and the metal surface stone polishing pads  is not kept firmly binding the abrasive chemical metallurgical bonding, actually only be mechanically entrapped abrasive coating metal inlay, thus gripping force is small, efficient grinding diamond particles heavier load and easyOff (or plating flaking) and lead to an overall failure; gripping force to increase the coating thickness must be increased, and the results highly abrasive bare chip space is reduced, wheel prone to clogging, the cooling effect is poor, prone to burn the workpiece surface. CurrentlyDomestic  concrete saws electroplated grinding wheel manufacturing has not been achieved by optimized processing conditions required to design the best grinding wheel topography, single electroplated diamond grinding these inherent drawbacks will be significantly limited its efficient grinding applications.

Diamond powder and reducing segregation and aggregation

 Pelleting process in ancient Chinese medicine processing to get the application and development. Now widely used in the pharmaceutical industry, the preparation of powder metallurgy materials and alloys, metallurgy, ceramics and fertilizer industries. In recent years, the production of diamond tools in order to improve production efficiency ferrules and quality, so that it can automate production, and the development and application of the pelleting process.
Pelleting process in powder metallurgy and diamond tool industry was application and development, mainly due to it has the following advantages:
1. Improved flowability and improved. After granulation powder having a particle diameter of a large particle size than the original powder, each particle is surrounded by the number of particles may be exposed to reduced, so the adhesion, cohesion and mutual friction greatly reduced, thereby to improve and increase the particulate material mobility.
2. Diamond powder and reducing segregation and aggregation, more uniform distribution, improving the performance of products. Granulation process prior to powder, diamond mixed with a binder, and then add solvent mixing and granulation wetting again, every single diamond powder wrapped in quilts are then cold pressing and sintering, thus preventing polishing pads for granite  segregation and diamond powder aggregation, thereby increasing the sintering properties of products, uniformity and stability of the product.
3. Improve the accuracy of the product size and weight, since the mixed powder to improve flowability, the powder products more uniform loading of the cold, cold products, improve the accuracy of the geometric dimensions and weight. This repression shaped products, sandwiches, laser welding blade tips and the transition head better.
4. Reducing the loss of cold mold. Since the metal grinding wheel  powder fluidity, diamond powder parcels were distributed more evenly, so the cold mold loss reduction, die life by 50 or more.
5. Improve the efficiency of the process cold and economy, in order to achieve the cold automated production to create the conditions. As the improvement of powder flowability, die life, so that ordinary cold press automatic weighing more efficient, making the volume of the adoption of automatic cold press possible. A foreign company 32VPM volumetric cold press, according to the head design, the operating parameters entered into the computer, basically metal grinding wheel  do not care personnel, automatic production. Granulation and displacement using cold press, the head is reduced to suppress the time from 32S 10S; die life by a 12,000 increase to 25,000; cold reduced costs from $ 0.35 to $ 0.11.
6. Reduce body powder pollution hazards to workers. After pelleting process used to reduce fine particles easily broken, easy storage and transportation, so that dust emissions and pollution greatly reduced.

the depth is involved in diamond cutting wear

( 1 ) diamond saw blade speed: in practical work , diamond saw blade line speed is equipment conditions , and is limited to the quality of the blade sawing 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 diamond bandsaw blades  is appropriate. In the production of granite tiles, use a smaller diameter diamond saw blades , wire speed can reach 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  turbo diamond blade 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 ) diamond saw blade feed rate : Feed rate Jibei sawing stone 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 cutting discs  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 .

Determination of diamond grinding wheel diamond content Tablets

How to determine the content of the diamond film diamond wheel, we must first understand what it is per cubic centimeter (cm3) containing the number of carats (ct) diamonds to be calculated. Details as follows:
  1. 1.1ct/cm3 = 25%, 2.2ct/cm3 = 50%, 3.3ct/cm3 = 75%, 4.4ct/cm3 = 100%, 5.5ct/cm3 = 125%.
  2. Ct diamond carat refers to  polishing pads for granite the weight not volume, 1ct = 0.2g.
  3 This method is the total content of the resin bond diamond wheel method. Ceramic metal-binding method and binding method, combined with the exception electroforming method.
  4 low levels were used to reduce abrasive grinding Omo impedance, high levels were used for forming an acute  grinding wheels angle grinding in order. Circular or other special shapes.
5 to diamond resin grinding wheel specification illustrate SDC150P100B that SDC diamond abrasives - 150 grit thickness - P end-stage combined hardness - content 100% (per cubic centimeter containing 4.4 kt diamond abrasive) -. B Resin France this content method of accounting in the resin bond diamond wheel method. ceramic metal-binding method and binding method, combined with the exception electroforming method.
Wheel during high speed rotation, if flying or fragmentation can cause casualties, mainly due to low quality  abrasive tools or wheel mounted card irregularities. Second, in the process of grinding wheel will produce a lot of powder layer, the operator needs to wear a mask, or prolonged inhalation of this powder layer will lead to respiratory diseases, lung diseases.
