This paper only analyzes how the raw materials are mainly phenolic resin and glass fiber mesh affect the quality stability of the resin grinding wheel. The most outstanding quality stability of resin grinding wheels is as follows: (1). The change of product strength and cutting performance of resin grinding wheel within a certain period (under normal air temperature and humidity conditions); (2). The change of the strength and cutting performance of each grinding wheel of the resin grinding wheel during the production cycle (such as different seasons in a year). Both of the above cases can be expressed by the measured strength retention rate and the thin flat cutting disc performance reduction rate. The influence of raw materials on the quality stability of resin grinding wheels is mainly reflected in: (1). Liquid phenolic resin. The fluctuation range of solid content, viscosity, gel time and water solubility of liquid phenolic resin has different degrees of influence. Therefore, the grinding wheel manufacturer must combine its own mixing, molding and hardening process characteristics according to its own product performance requirements. , develop the technical indicators and scope of liquid resin suitable for you. In addition, the liquid phenolic resin must be properly stored because the liquid phenolic resin is inherently unstable, and the specifications will change even at room temperature. The grinding wheel manufacturer must store the liquid phenolic resin under low temperature conditions to ensure the stability of the liquid phenolic resin, thereby ensuring the stability of the resin wheel mixture and ensuring the stability of the resin wheel quality. (2). Powder phenolic resin. For powder phenolic resins, flow length (fluidity), particle size (grain size, fineness), urotropine (six times) content and gelation time fluctuations all affect the quality of the grinding wheel. In this regard, the flow of the flow should be considered first. These indicators illustrate the behavior of the resin under certain experimental conditions. They are only the performance of the resin, and the extent of the impact on the performance of the grinding wheel can only be determined by the actual application of each resin wheel factory. The flow of the powder resin is the most important performance index affecting the structure of the binder. The particle size (grain size, fineness) affects the amount of the wetting agent, and the content of the volatiles (free phenol, water) is also important. In the actual grinding wheel production process, it is necessary to ensure the stability of the performance of each batch of powder resin, so as to ensure the quality of the grinding wheel. (3). Stability of the technical indicators of the mesh The mesh was originally applied to the resin wheel and the most important role was to increase the strength of the wheel. As the performance of the resin grinding wheel continues to increase, the role of the mesh in the resin grinding wheel is very important. Mainly manifested in: fluctuations in the strength of the grinding wheel, deformation of the slice (mainly double-wire grinding wheel), delamination of the grinding plate, and so on. The thickness of the mesh has an influence on the strength and viscosity of the cutting disc for stainless steel and the cutting and grinding performance of the resin grinding wheel. In theory, under the condition that the grinding wheel production process is stable and allowed, the mesh with the higher amount of glue, the grinding wheel The higher the strength, the better the bonding performance and the more stable the cutting.

There are many quality problems in the production process of resin grinding wheels. Since the manufacture of 12 inches cut off wheel is a multi-disciplinary synthesis of composite materials, the causes are complicated and numerous. Raw material problem Resin grinding wheel is a complex system composed of a variety of main and auxiliary raw materials. As long as the material is abrasive and bonding agent, the auxiliary material includes filler, reinforcing material, coloring agent and the like. 1. Problems that should be concerned about abrasives At present, the quality of abrasives on the market is uneven, mainly as follows: (1). The chemical composition of the abrasive is often qualified, but the physical properties are poor; mainly due to the gap between the bulk density of the abrasive and foreign countries. (2). The particle size composition of the abrasive is chaotic, which is quite different from the standard specification; it is mainly manifested in the difference between the basic particle content of the same grain size abrasive and foreign countries. 2. In terms of binder, mainly phenolic resin: (1). Resin quality stability problems, especially the level of free phenol in the resin. Excessive free phenol content will accelerate the cracking of the resin after heating and hardening of the resin wheel, affecting the strength of the grinding wheel; (2). Mixing uniformity of resin powder and urotropine, urotropine as a hardener of resin, insufficient addition of urotropine, incomplete hardening of resin, affecting the strength and hardness of the grinding wheel; Excess urotropine does not combine with the resin, and decomposes and volatilizes during the hardening process, which increases the pores of the grinding wheel and reduces its strength and hardness. (3). The binder particle size is too thick or too fine: It is generally believed that the particle size of the binder is fine, which is advantageous for uniform distribution of the binder. If the particle size is too coarse, the molding material is not easily mixed uniformly, which affects the hardness and strength of the standard cut off wheel for metal. Even for the coarse-grained resin sheet cutting wheel and the shaped grinding wheel, the size of the binder (resin powder) selected should be finer than 320#. However, if the particle size of the phenolic resin powder is too fine, the mixing is difficult, and the uniformity of the mixture is difficult to be achieved, thereby affecting the cutting performance of the resin grinding wheel.

In daily use, the maintenance of super thin 115 cutting disc can greatly improve their service life. Let me introduce how to do it. 1. If there is viscous material such as glaze or paint on the cutting piece, remove it with a grinding wheel or sandpaper. 2. Do not use the cutting piece for grinding or bending. The normal function of the cutting piece is used for straight cutting. 3. Cutting sheets for rapid cutting of granite, marble, concrete, cement materials, ceramics, bricks and other inorganic non-metallic hard and brittle materials, can also be used for cutting such as asphalt, cinder blocks, soft cement, sand joints, etc. Soft material. Do not cut the metal, as it will make the saw blade dull and shorten the life. 4. If the cutting piece is used for a period of time, the surface is smooth, the diamond blade is small, and the cutting piece is not sharp. The correct way: re-blade with a grinding wheel or refractory brick to facilitate the removal of the metal carcass wrapped part so that the diamond is normally out of the blade, and the sharpness of the cutting piece is improved. It is not possible to use the saw blade that has been polished continuously, and it is not possible to use the overheated cutting piece continuously.

Some common sense before choosing and using diamond cutting blades Before choosing and using China cutting disc for metal, users must understand the following common sense about low price disc for metal : 1. The difference between CVD diamond coating and amorphous diamond coating Amorphous diamond (also known as diamond-like carbon) coating is a carbon film deposited by PVD process. It has a part of diamond SP3 bond and a part of carbon SP2 bond; its film hardness is very high, but lower than the hardness of diamond film; its thickness is also thinner than the diamond film we usually deposit. When processing graphite, the life of amorphous diamond coated tools is 2 to 3 times that of uncoated cemented carbide tools. In contrast, CVD diamond is a pure diamond coating deposited by CVD process. The tool life of processing graphite is 12 to 20 times that of cemented carbide tools, which can reduce the number of tool changes and improve the reliability and accuracy of processing. consistency. 2, can not use hard diamond tools to process hardened steel Diamond is composed of carbon atoms. When some materials are heated, they absorb carbon atoms from the diamond and form carbides in the workpiece. Iron is one of these materials. When machining iron-based materials with diamond tools, the heat generated by the friction causes the carbon atoms in the diamond to diffuse into the iron, causing the diamond coating to fail prematurely due to chemical wear.

How to use the thin flat cutting disc correctly 1. The correct choice of cutting machine should pay special attention to the power, speed, rigidity and precision of the cutting machine. ¢150 below the diamond saw blade should be used 1 ~ 1.5KW, speed 7255 ~ 14500r. pm adjustable speed cutting machine, ¢ 150 ~ 230 saw blade should use 1.5 ~ 3KW, speed 4000 ~ 11000r. pm adjustable speed cutting machine; The diameter stone saw blade should be 15HP (electric) or more, the line speed is 20~60m/s, and the speed cutting machine should be used. The medium diameter engineering saw blade should be 30HP (electric) or 55HP (gasoline or diesel power) or above, and the line speed is 35~. 70m/s adjustable speed cutting machine; the power of large-diameter saw blade cutting machine is related to the diameter and number of saw blades. For example, the domestic general ¢1600 single-piece sawing machine has a power of 37~45KW and a speed of 270~360r.pm. 2. The correct installation of the diamond circular saw blade and the installation accuracy are closely related to the cutting efficiency, cutting quality and service life of the saw blade. After installation, ensure that the saw blade runs smoothly during the cutting process without vibration (except for the quality of the saw blade itself and the rigidity of the cutting machine). When installing the saw blade, first make sure that the direction of the cutting edge indicated on the saw blade is the same as the direction of rotation of the cutting machine spindle; to clean the surface where the saw blade mounting hole, the cutting machine spindle and the flange are in contact with each other, it is necessary to ensure that they are cleaned. The contact between the flat and good; the diameter of the flange should be reasonably selected according to the diameter of the saw blade. If the cutting disc for stainless steel is too small, the end face of the saw blade will be large when the flange is too large. If the flange is too large, the weight of the spindle will increase, which will increase the runout and reduce the processing depth of the material. After installation, the blade and flange must have the specified value to reach the specified value.

Diamond diamond material. With the rapid development of automotive, aerospace and aerospace technologies, the requirements for material properties and processing technology are increasing. New materials such as carbon fiber reinforced plastics, particle reinforced metal matrix composites (PRMMC) and ceramic materials are widely used. These materials have high strength, good wear resistance and low coefficient of thermal expansion, which determines the tool life is very short when machining them. The development of new wear-resistant and standard cut off wheel for metal is a subject of research in many universities, research institutes and enterprises. Diamond combines many excellent properties such as mechanics, optics, thermals, acoustics and optics. It has extremely high hardness, low friction coefficient, high thermal conductivity, low thermal expansion coefficient and low chemical inertness. It is an ideal material for manufacturing tools. 12 inches cut off wheel is a cutting tool widely used in the processing of some hard and brittle materials such as concrete, refractory materials, stone, ceramics. The diamond grinding wheel is mainly composed of two parts; the base body and the cutter head. The main supporting part of the bonding head is the base body, and the cutting head is the part that cuts during use. The cutting head will be continuously consumed during use, and the base body will not, the reason why the cutting head can The effect of cutting is because it contains diamond, which is the hardest material at present, and it rubs and cuts the object to be processed in the cutter head. The diamond particles are wrapped in metal inside the cutter head.

Grinding wheel refers to an abrasive tool made of abrasive and bonding agent, commonly known as “industrial grain”. The main components are abrasives and binders. Grinding wheels can be divided into: 1. Fine grinding rubber grinding wheel for fine grinding and medium grinding; Second, the high performance cutting disc is used for centerless grinding, and the guide wheel drives the workpiece so that the external dimensions and shape of the workpiece are not deviated; Third, the cutting wheel, used for cutting machine slotting, referred to as cutting piece, super-cut cutting wheel is generally within 5mm; Fourth, the polishing wheel is mainly used for polishing and polishing. Grinding wheel introduction: A fixed abrasive having a round hole in the center made of an abrasive, a binder, an adhesive or the like. Grinding wheel is the most widely used abrasive tool. The grinding wheel rotates at high speed. It can grind, semi-finish, finely grind and superfine the outer, inner, flat and other surfaces of metal and non-metal workpieces. Grind and cut the cut. Grinding wheel classification: According to different abrasives, the grinding wheel has ordinary abrasive grinding wheel (corundum grinding wheel and silicon carbide grinding wheel), natural abrasive grinding wheel and super-hard abrasive grinding wheel (diamond and cubic boron nitride CBN, etc.); According to the shape, it can be divided into flat grinding wheel and special-shaped grinding wheel (beveled grinding wheel, cylindrical grinding wheel, dish-shaped grinding wheel, bowl-shaped grinding wheel, cup-shaped grinding wheel, etc.); according to different bonding agents, it can be divided into ceramic bonding material grinding wheel and resin bonding material grinding wheel.

In the daily cutting process, the loss value of the 12 inches cut off wheel is an important problem for the enterprise to overcome. How to maximize the use of the grinding wheel in the operation process is the basic operation method: 1) The finer the grain size of the grinding wheel, the smaller the roughness value 2) Abrasives should be selected that have affinity with the workpiece material 3) The hardness of the abrasive tool, when the workpiece material is soft and sticky, a harder abrasive tool should be used; when it is hard or brittle, a softer abrasive tool should be selected. 4) Using a grinding wheel with a larger diameter of the grinding wheel, increasing the width of the grinding wheel can reduce the surface roughness 5) Using a diamond pen with good wear resistance, suitable cutting edge shape and installation angle, when the dressing amount is appropriate (the longitudinal feed amount should be smaller), the abrasive cutting edge can obtain good contour and reduce the surface. Roughness. Analysis of the characteristics of grinding wheel abrasive The grinding work of the abrasive is carried out under the conditions of high speed rotation, high temperature, high pressure and grinding fluid. Therefore, the abrasive needs to have: high hardness, suitable toughness, self-sharpness and chemical stability. Abrasive hardness: refers to the degree of resistance of the abrasive when it is pierced. Toughness: The ability of an abrasive to withstand pressure without breaking or cracking. Grinding wheel abrasive properties: It must have a very hard mineral crystal structure to be able to crack without excessive pressure during grinding. When subjected to an external force during processing, it can have good toughness, is not easily deformed, and is not easily worn. It must have heat resistance, local high temperature generated during the grinding process, it is not easy to melt the particles, and there may be burned parts. At the same time, the grinding wheel abrasives also need to have chemical stability, because the standard cut off wheel for metal grinds a wide variety of workpieces, steel, ceramics, gemstones, cloth, causing chemical instability, which is quite destructive to the workpiece.

Abrasives are one of the important parameter properties for measuring the characteristics of resin EN12413 cutting discs. By analyzing the characteristics of various abrasives, we can find the most suitable abrasive for workpiece grinding, and then select the grinding wheel that is most suitable for workpiece grinding. Abrasives are divided into natural abrasives and artificial abrasives. Natural abrasives have a variety of corundum abrasives and diamonds; natural corundum has more impurities, internal distribution is uneven, the price is high, and it is less used to directly make grinding wheels. The abrasives currently used to make grinding wheels are mainly artificial abrasives. There are corundum abrasives, silicon carbide abrasives, and superhard abrasives. Analysis of several commonly used artificial corundum abrasives: The main component of the corundum abrasive is aluminum oxide (AL2O3); it is obtained by high-temperature melting from bauxite. Suitable for grinding materials with high tensile strength. According to the content of aluminum oxide, internal crystal structure and other impurities, corundum is divided into brown corundum, white corundum, chrome corundum, etc.: 1. Brown corundum (A) Also known as alumina (ALO), the color is tan. Brown corundum ceramic wheels are often blue and light blue. Brown corundum has high hardness and toughness and can withstand large grinding pressure. It is suitable for grinding carbon steel, alloy, high-hard bronze and other metals. Brown corundum abrasives are cheap and widely used. 2, white corundum (WA) White corundum containing alumina is extremely high purity, white color, also known as white alumina, white corundum grinding wheel is harder than brown corundum, sharp grain. When grinding, the abrasive grains are not easy to be blunt, and the blunt abrasive grains are also easy to fall off to reveal new abrasive grains inside, which has quite good self-sharpness. The 6 inch es cutting disc has good machinability, and the heat generated during grinding is lower than that of brown corundum. It is mostly used for hardened steel, high speed steel and easily deformable workpieces. 3, chrome corundum (PA) chrome corundum because it contains a small amount of chromium oxide, it is red rose, pink. Its hardness is comparable to that of white corundum, and its toughness is higher than that of white corundum. When grinding high-vanadium and high-speed steel, the grinding wheel is more durable than the white corundum grinding wheel, and the working efficiency is higher. The same type of chrome corundum grinding has higher thickness than white corundum, suitable for forming grinding, instrument parts and each High-gloss surface finish. 4, microcrystalline corundum (MA) color is light brown. The content of aluminum oxide is 94% to 96%, and the 10% fine corundum crystal has high toughness and self-sharpness. Suitable for precision grinding of stainless steel and bearing steel. 5, single crystal corundum (SA) single crystal corundum is a single crystal smelted by a special method. It does not mechanically pulverize like other abrasives, so there is no damage and residual stress inside the abrasive grains, hardness and toughness are higher than white corundum. High durability during grinding. It is suitable for grinding tough stainless steel, high vanadium high speed steel and other difficult materials. It is also used in ultra-precision grinding.

The free sample cutting disc is a cutting device that many users now choose when they are cutting equipment. What problems should be paid attention to after the purchase and its specific use and precautions? Let me introduce you today. 1. If the blockage is found to be swaying during cutting, the cutting should be stopped immediately. After the block material is fixed firmly, it can continue to work. During the cutting, it is not allowed to move the block material arbitrarily. 2. When cutting, it is found that the saw blade has obvious deceleration or even the phenomenon of clamping. It may be caused by the belt slipping, loosening of the compression nut or too much depth of the knife, too fast cutting speed, etc., and should be adjusted in time. 3.The line speed should be compatible with the hardness and wear resistance of the processed stone, it is recommended to select the following line speed to cut different types of stone. Tip: Increase the cutting efficiency when the line speed is not high, which will reduce the life of the saw blade. 4.The use of diamond saw blade technology, feed speed, mainly depends on the performance of the material, for each material when the depth of cut is a certain range of feed speed, if the speed is too high, it will accelerate the wear of diamond Even falling off, causing the saw blade to consume too fast, if the speed is too low, it will make the saw blade self-sharp process not work properly, thus "blunt, slip" loss of cutting ability. Under normal circumstances, the feed speed should be slow when cutting in, and should be uniform when sawing. For common typical materials, when the depth of cut is 20mm, the following feed speed table is recommended for your reference. When the thickness changes, the cutting speed can be Converted by the cutting area (cm2/min).

The cutting piece is selected too hard, the blunt abrasive grains are not easy to fall off, the high performance cutting disc is easy to block, the grinding heat is increased, the workpiece is easy to burn, the grinding efficiency is low, and the surface quality of the workpiece is affected; the cutting piece is selected too soft, and the grinding grain is still sharp. When it falls off, it increases the loss of the cutting piece, and it is easy to lose the correct geometry and affect the accuracy of the workpiece. Therefore, the selection of the hardness of the cutting piece should be appropriate, and should be comprehensively considered according to the contact area of ​​the cutting piece and the workpiece, the shape of the workpiece, the way of grinding, the cooling method, the type of bonding agent of the cutting piece and the like. 1. When grinding soft materials, choose a harder cutting piece. When grinding hard materials, choose a soft cutting piece. 2. When grinding soft and tough non-ferrous metals, the hardness should be selected to be softer; 3. Grinding materials with poor thermal conductivity should be selected as softer cutting blades; 4. When the end face grinding is more than the circumferential grinding, the hardness of the cutting piece should be selected softer; 5. Under the same grinding conditions, the hardness of the cutting piece with the resin bond is 1~2 lower than that of the ceramic bond cutting piece; 6. When the cutting speed of the cutting piece is high, the hardness of the cutting piece can be softly 1~2 small; Cutting piece balance Due to various reasons in the manufacture and installation of the dicing sheet, the center of gravity of the dicing sheet often does not fit with its center of rotation, which causes the grinding wheel to vibrate at high speeds, which affects the processing, and causes the rupture of the dicing sheet when it is severe. The machine tool is damaged, so the cutting piece must be statically balanced after it has been mounted on the flange. After the cutting piece is mounted on the flange, the flange is placed on the mandrel and placed on the gimbal rail. If it is unbalanced, the heavier part of the cutting piece will always turn to the bottom, move the balance block position inside the ring tip of the flange, balance the center of the cutting piece, and repeat until the cutting piece is free on the guide rail. The position can be still, and the cutting piece reaches a static balance. When installing a new cutting piece, the thin abrasive cutting disc for metal is statically balanced twice. After a static balance, install the grinder and trim the shape of the cutting piece with a diamond pen, then remove the cutting piece and perform a static balance before installation.
