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.

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 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.

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 saw blade grinding requires excellent technical

There are many small factories saw blade grinding , hand workshops on the market now ; grinding only the serrated blade rake angle , a simple rough treatment, after treatment has changed the original blade angle , the blade angle , side angle , and tooth room is simply not deal with the conditions , do not be detected , correction of its processed products after grinding .

 Grinding time is longer , etc., make a note to tell you about our grinding process testing process , and related technical standards.

B. Then the angle with the dial gauge testing, including tooth rake angle ; hind ; side angle detection ( see no cracks , chipping , etc. ) , and then put on the projector to enlarge 50-100 times to determine the original angle serrated blade wear ; If the tooth chipping small , we can improve the grinding appropriate amount to reduce production costs.

 C. If you have alloy teeth need to be replaced , use of automatic welding machine for gear tooth exchange operations. D. Next, correction for blade stress , this step is critical blade grinding step ; requires highly experienced technicians to the completion of the diamond blade during high speed operation , the external force, the stress in the blade has been changed , it will appear saws Road bigger ; surface roughness phenomena ; we stress adjustment requires two more times ; If you can correct cutting discs  the standard range , then into the next process , on the contrary , we will contact the customer to solicit customer feedback, customer requirements as grinding, we are precision grinding, however , after the completion of the package , we will blade , diamond saw blade attached deviation specific data. We first used Japanese imports 200 grinding diamond wheel for coarse grinding particle size , particle size and then use the 600 wheel for precision grinding.

  E. Next check the vibration rate , after passing by the B -step process , final inspection, shipment region after placing fully qualified , work orders by businesses to complete the polishing process .

 Under such strict procedures , our sanding discs  products will ultimately into the hands of customers , in this sense , our products are definitely stand the test of time.

Field of use of diamond tools

Diamond is the hardest, so in stone, building materials processing, diamond cutting tool is a good tool. Diamond tools such as diamond saw blades and wear-resistant materials in non-ferrous metal processing applications, has excellent adaptability. Use the following detailed description of the field of diamond tools.
When using diamond tools, users  concrete diamond blades have two options: one is polycrystalline diamond (PCD), the other is a relatively new chemical vapor deposition (CVD) diamond.
Early use of proven performance
Polycrystalline diamond has a natural diamond hardness, strength and abrasion resistance, but does not damage the sensitivity of natural diamond. It is at high temperature, the polymerization of the synthetic diamond particles. In the process, while the polycrystalline particles is integrally formed is bonded to a cemented carbide substrate on to improve the mechanical strength and impact resistance.
PCD is applicable to high-speed cutting of aluminum, is particularly suitable is required to achieve good surface roughness of the main case, it is in the processing of high wear resistance, and exhibits excellent performance. Typically, PCD recommended for cutting high silicon aluminum alloy, but also for brass, copper, bronze, and carbide processing. Processes used include turning, boring, profiling, grooving, milling and hole processing.
As the chemical reaction between the diamond and iron, in general, does not apply to the processing of ferrous metals PCD material. However, it can deal with the processing of bi-metal material, comprising a combination of aluminum and iron included. For example: a car parts suppliers in the processing of aluminum and cast iron cylinder bi-metal body with a diameter of 305mm wafer type face milling cutter, corner radius 2.36mm, with repair knife, cutting 304.8m/min, feed 0.10 mm / tooth, depth of cut 5mm, processing up to the 5000 cylinder block, indexable inserts only need one.
By the mass production industry, primarily grinding cup wheels  in the automotive industry increasing push aluminum processing speeds. Meanwhile, car manufacturers in order to reduce weight and reduce costs, is on the use of metal matrix composites evaluated, and such materials must be processed by PCD. He said: "Such material can not be processed using carbide tools."
Polycrystalline product manager, said that although the PCD development achievements have been giving a very deep impression,
PCD tools in terms of scope and production efficiency, have brought many benefits to the process. Although the diamond is the hardest available materials, the material characteristics and toughness problems still further. One factor to improve the toughness of PCD is plus cobalt is not directed it into a random arrangement between the diamond grains. Further, the cemented carbide substrate of the diamond abrasive layer can also act as a mechanical support, thereby increasing the impact resistance, and ease of manufacture of brazed tool.
Another benefit of the PCD, the existing series of various grades have been able to meet any need to use non-ferrous metal processing. In general, the fine particles are less wear diamond for materials processing require very high surface roughness of the occasion; diamond  sand paper particles in general as generic brands machining; coarse diamond for roughing the special anti-wear material, but the surface roughness of less demanding place.
Bright future
At present, many production sites do not take full advantage of the diamond. The reason is that a lot of speed and torque tools are not sufficient to ensure the efficient functioning of the tool.
In addition to mechanical problems, there is a difficult problem is to convince people to produce the factory, do not just stare at diamond (PCD or CVD diamond) set the initial price, but to see it brings cost savings and improved performance benefits. You can make a diamond tool than conventional operation (depending on machine performance may be) at a higher speed, thereby enhancing the volume of output. Meanwhile, fewer tool changes. Assume diamond carbide than 50 times to 100 times higher life, you do not often stop it.

etermine the characteristics of the grinding wheel grinding process system can make even micro cutting

 Grinder with grinding wheel as the cutting tool on the workpiece machining methods. This method features:
 (1) Since the abrasive grinding wheel itself wet polishing pad  has a high hardness and heat resistance, high hardness can be processed so grinding materials such as hardened steel, carbide, etc..
 (2) determine the characteristics of the grinding wheel grinding process system can make even micro cutting, the general ap = 0.001 ~ 0.005mm; grinding speed is high, generally up to v = 30 ~ 50m / s; grinder stiffness; adopts hydraulic transmission Therefore grinding energy and affordable access to high precision (it6 ~ it5) small surface roughness (ra = 0.8 ~ 0.2μm). Grinding parts finishing the main methods.(3) As intense friction, leaving the grinding zone temperature is high. This can cause deformation of the workpiece to produce stress, and even cause surface burns. Therefore, a lot of grinding coolant must be injected to reduce the grinding temperature. Coolant may also function as a lubricant chip (4) grinding large radial force. This will cause the machine - grinding wheel - workpiece system flexibility retreat, so that the actual depth of cut less than the nominal depth of cut. Therefore, the grinding will be completed when the light is not to be  diamomd core drill bits infeed grinding to remove the error.(5) After blunt abrasive, grinding force also increased, resulting in grain crushing or off, exposing sharp edges again, this feature is called "self-sharpening." Self-sharpening grinding a certain period of time to make normal, but after more than a certain work should be carried out manually trimmed to avoid grinding force increases caused by vibration, noise and damage the workpiece surface quality.Wheel speed working conditions, in order to ensure safety, should be checked before installation, there should be no cracks and other defects; wheel work to make a smooth, dynamic balance test should be carried out before use.Grinding work after a certain time, its surface will be void debris clogging the abrasive concrete saw blades  acute angle will blunt the original geometry is distorted. Therefore, to restore the cutting ability of the dressing to be correct geometry. Wheel dresser diamond pen required.Structure and surface grinder grinding motionMany different types of grinding machines, mainly surface grinder, cylindrical grinder, internal grinder, universal cylindrical grinding machine (also can grind the hole), gear grinding, thread grinding machine, rail grinding, centerless grinding (grinding cylindrical) tool grinder (grinding tool ), etc.

Aluminium and aluminum grinding wheel grinding program which

1, the hardness is low intensity : The maximum hardness of aluminum HB110 ~ 120, the maximum tensile strength is generally 20 ~ 30kg/cm2. Low hardness , scratch resistance of a material to plastic deformation or poor , the grinding surface is easily scratched and bumps .
2 , the plastic ductility large , the grinding process produces plastic adhesion , blocking wheel surface ; while a low melting point alloy (660 ~ 780 ℃), the temperature in the grinding zone , the  marble polishing pads surface of the metal melt , adhesive wheel surface , resulting in the increase of the melt adhesion of the blocking wheel .
3, the linear expansion coefficient: the grinding action of heat , the aluminum alloy is easy to cause deformation of the workpiece , thus affecting the precision grinding of the workpiece surface .
4 , the grinding efficiency is low : in order to overcome the alloy produced in grinding the workpiece thermal deformation , reducing the grinding wheel surface adhesion blocking , to ensure the surface quality , to increase the number of dressing , ordinary steel is about 3 times , thus reducing the grinding productivity.
Second, the choice of grinding wheel aluminum : Aluminum grinding process the biggest problem is the " stick" , " block "
A, aluminum ultra- fine grinding , mirror grinding : Use the "PVA" wheel, equivalent to Japan 's "UB" wheel . Can achieve the effect of the mirror . The grinding wheel is also  fibre discs similar in structure and ceramics ( see below ) .
B, aluminum and semi- coarse grinding :
1 , abrasives : The brittle and sharp black silicon carbide .
2 , binding agents : Use with high strength ceramic binder , and oil, acid, alkali, corrosion resistance .
3 , particle size : to meet the requirements of the case using the coarse number. Coarse : selection of 36 to 46 # ; grinding : the use of 60-80 ; coarse grit No. relatively small number of participating grinding , grinding, less heat , reducing the deformation of the workpiece and the grinding wheel clogged ;
4 , hardness: should opt for a  granite core bits lower hardness, the grinding wheel to maintain a good self-sharpening . Generally used in H ~ J hardness .
5, the organization : an organization should adopt a more accommodating loose debris , so that the cooling fluid into the grinding zone , enhancing the cooling effect, reducing the grinding zone temperature . Should be used in large pores wheel loose organization , with good grinding effect .

For special non-standard tool drilling

Currently, a variety of large composite fastener holes required in the processing more, the machine becomes more and more of a challenge and complexity of a large number of deep hole machining. These are two completely different application areas, but the common denominator is carbide tipped saw blade  processed in order to obtain satisfactory results and competitive processing performance, you must use the customization tool.
Non-standard tool is ideal for cutting the parts completely or partially cutting tool is based on the concept has been proven standards such as the existing blade clamping device, shank and interfaces; it might be equipped with multiple criteria a dedicated blade holder, can be used as two or more standard tool usage; also be a special cemented carbide material and / or channel made of indexable inserts, the use of maximum efficiency, and to provide a longer, more stable tool life. Associated with non-standard tool also includes incomplete standards, as an alternative to standard tool with a very small deviation characteristics.
When you need to process more complex parts, the part of the various features require specialized non-standard tool solutions. This also applies to the processing of simple parts, because the non-standard solutions can eliminate production bottlenecks encountered. The non-standard tools as the best solution for many occasions, including most  cutting blades of the machining range, materials and type of industry, which is the most representative of most of the non-standard tool modular tooling solutions. These solutions are usually based on criteria such as blades, knife cards, tool interfaces, flute, anti-vibration system or tool holder clamping device based on various combinations. With unique properties accounted for purely non-standard tool nearly a quarter of the total number of non-standard tools, and similar to the standard tool for non-standard tools accounted for three quarters.
Processing areas of processing and deep parts made of composite material is that the main processing of the use of non-standard tool places, such composite materials are mainly carbon fiber ring saw blades  reinforced plastic (CFRP), and by stacking the metal support of the composite material of the material.
Deep processing is widely used in a variety of industries, most notably in the energy industry and the aviation industry. Some deep parts are usually difficult to process or that seem difficult to begin processing, but the use of non-standard custom tooling solutions can, through an efficient and secure way to easily solve this problem.

Inner circle grinding mechanical transmission

 Inner circle grinding is generally divided into four types: wind-driven inner circle grinding, high-speed electric aerostatic bearing inner circle grinding, mechanical drive and electric grinding inner circle inner circle grinding.Wind-driven inner circle grinding: spindle with  concrete saw blades  a turbine driven by compressed air turbine rotates the spindle speed, spindle speed reaches 10000R/MIN. Moreover, small vibration, pressure can be adjusted stepless. And with regulators, filters and other accessories.Aerostatic bearing speed electric grinding inner circle: The aerostatic bearing (supply pressure is 40 ~ 65MPa), grinding system rigidity, both electric grinding characteristics, speed up 180000R/MIN, suitable for grinding a ~ 10MM hole.Inner circle grinding mechanical transmission: mainly by the spindle, bearings, sleeve body shell, flat supporting pulleys and other components. Then, after replacement of the long axis, is used to grind different bore diameter and  granite polishing pads length, for comparison, the use of low speed, the speed is generally lower than 2000R/MIN.Electric grinding inner circle: A three-phase asynchronous motor direct drive, and another by a high-frequency electric motor driven spindle speed of up to 50000 ~ 90000R/MIN. Output power is larger, instantaneous overload, speed characteristics hard, little vibration.enerally the heat generated by the grinding process will burn the workpiece, so you need to use coolant to promptly take the heat, this is called wet. However, grinding tools is a special application, as part of more complex shape, machining accuracy is relatively high, most of the processes set by manually, there is no way to use wet methods. In theory, the hardness of steel molds are high, and SG monocrystalline corundum grinding wheel is the best option.

diamond truing tool used for attention

1 using the new dresser, before finishing the last feeding should exit. Many crisp diamond dressing tools, at the beginning of his contacts with the wheel, are easily damaged.
(2) in an inclined angle of 10 ~ 15 ° diamond dressing tool head mounted to point to the direction of rotation of the wheel.
3 securely installed or clamping dresser dressing tool, not the tool head hanging too long.
4 Where possible, try to use  carbide tipped saw blade coolant. Throughout the finishing time, with coolant pouring dressing tool and the wheel contact point.
5 In the dressing beginning from the highest point of repair from the grinding wheel, usually the middle wheel.
6 Note that except for a slight amount of repair. In addition to the maximum depth of repair, except for tinkering: 0.001 to 0.002 inches. Except for finishing: 0.0005 to 0.001 inches.
7 Press the relevant manuals choose the right lateral quickness. The slower moving laterally (in the allowable range), the lower surface roughness obtained wheel.
8 must be within the specified time interval for dressing the grinding wheel to prevent the wheel blunt, the grinding force increases.
9 at predetermined intervals, the toolholder the dressing tool rotating 1/8 turn, to ensure that the dressing tool is always sharp.
10 When the diamond dresser or tool head blunt or obvious change in peacetime, should be timely adjusted and replaced.
11 According to the diameter of  metal grinding wheel the wheel, the amount of a reasonable choice of diamond CARAT (pure diamond content), the larger wheel diameter, the larger the value of the selected CARAT diamond.
Incorrect:
1 diamond dressing tools in place to clamp head, be careful not to bump into the wheel surface.
2 can not be a single point diamond dressing tool head vertically aligned wheel center to be inclined generally 10 ~ 15 °.
3 heat dressing tools can not be "quenched" (refers to sudden cold). In the dry dressing must be kept trimmed twice the interval sufficient to heat the dressing tool cooling.
4 wheel surface can not be assumed to concrete cutting  have ideal flat. When trimming the beginning to find the highest point of the wheel position for trimming.
5, if possible, in addition to the amount of each wheel of the repair, the radius of the wheel can not be more than 0.001 inches. In addition to the amount of the repair is too large diamond dressing tool head can cause premature wear and often broken.

A detailed description of the blade cutting parameters

Diamond saw blade cutting parameters
( 1 ) diamond blade speed : in practical work , diamond saw blade speed by equipment conditions , saw the quality and the nature of the restrictions before sawing stone . From the optimum blade life and cutting efficiency , it should be selected depending on the nature  granite blade  of the stone saw blade speed . Sawing granite , the blade speed at 25m ~ 35m / s within the selected range . For high quartz content and difficult cutting granite , remove the blade speed limit is appropriate. In the production of granite tiles , the use of smaller diameter diamond saw blade , wire speed can reach 35m / s.
( 2 ) Cutting Depth : diamond cutting depth is related to wear , effective cutting , saw cutting force conditions and the nature of the important parameters of stone . Generally speaking, when the line speed diamond saw blade is high, should be selected for cutting of small depth , from the current technology , the cutting depth of the diamond can choose between 1mm ~ 10mm . Usually with a large diameter saw blade cutting granite  fibre discs blocks , the cutting depth can be controlled within 1mm ~ 2mm between the feed rate should be reduced at the same time . When the line speed diamond saw blade is large , a large cutting depth should be selected . But in performance and tool strength saw the extent permitted , should try to take a greater depth of cut for cutting to improve cutting efficiency . When the machined surface when requested , should be used small depth of cut . ( 3 ) diamond saw blade feed rate : Feed speed incurs sawing stone feed rate . Its size sawing Plate Compactor  rate impact , the force and the cutting blade heat dissipation area . Its value should be based on the nature of the selected cutting stone . Generally speaking , sawing softer stone, such as marble, may be appropriate to increase the feed speed , if the feed rate is too low, more conducive to high cutting rates . Sawing fine structure , relatively homogeneous granite, may be appropriate to increase the feed speed , feed rate is too low if the diamond blade easily be polished . But sawing UNEVEN coarse granite structure , should reduce feed speed , otherwise it will cause the blade vibration and reduce fragmentation leading diamond cutting rates . Granite cutting feed rate is generally 9m ~ 12m/min within the selected range .
