Milling inserts have the highest precision among carbide indexable inserts, and the peripheral grinding machine are used for peripheral grinding of such inserts. Resin diamond wheel can be used for  peripheral grinding . At present, as for the peripheral grinding machines, the grinding wheel frame not only performs high-speed rotation but also axial swing, so that the grinding wheel is generally not trimmed during the whole grinding process to avoid huge waste. However, when the new grinding wheel is mounted on the flange, there is a coaxiality error between the grinding wheel and the flange. Therefore, when new resin diamond wheel is used for the first time, the grinding wheel should be trimmed so that the grinding wheel, the flange and the main shaft could rotate on the same axis. In this way, the wheel could have the correct geometry. Since the grinding wheel is expensive and generally not trimmed, the grinding wheel should be ensured uniform wear throughout the whole use process

CBN is a new type of superhard material with ultra-high pressure and high temperature technology after synthetic diamond using . CBN and its products are mainly suitable for precision grinding of tool steel, alloy steel, heat-resistant steel, stainless steel and other materials. Although the cost is slightly higher than that of general abrasive grinding wheel products, thermal stability and chemical inertness are superior to general abrasive wheels, diamond wheels, etc. Vitrified bond CBN grinding wheels are common used wheels during grinding process. Grinding performance of grinding wheels is different with diamond, CBN, silicon carbide and corundum abrasive. Diamond is the hardest abrasive, but it’s not ideal used for steel material with large grinding toughness due to poor thermal stability. Silicon carbide wears rapidly due to its low hardness and chemical activity to iron group metals. Corundum is a conventional abrasive used for grinding steel material, but the hardness is rel

High-speed and ultra-high-speed grinding technology research should be conducted with super-hard material CBN as a tool, modern ultra-high-speed cutting technology and modern high-flexibility and high-automation equipment to accelerate the practical process. The core key technologies for achieving high-speed and ultra-high-speed grinding to be gradually improved include high-speed and ultra-high-speed grinding mechanism research, high-power and high-speed motion unit equipment manufacturing technology, high-flexible and high-automation system, grinding center, research and development about super-hard abrasive micro-powder high-speed grinding wheel preparation technology and super-hard abrasive wheel dressing technology. Vitrified bond CBN grinding wheel is one of the most common wheels. The main research work about high-speed and ultra-high-speed grinding mechanism is to develop high-speed, ultra-high-speed grinding computer animation, vision and predictive simulation software with

Improving the quality of processing and the efficiency of grinding processing has always been an important goal in the field of grinding. The high-speed, ultra-high-speed precision grinding process is an advanced, high-quality and low-intensity developed manufacturing process technology in recent years. High-speed, ultra-high-speed grinding technology means that high-precision, high-automatic, high-flexibility manufacturing equipment can be reliably achieved with the super-hard abrasive grinding wheels to greatly improve the grinding speed to improve the material removal rate, processing precision and processing quality. CBN is cubic boron nitride with a microhardness of 800-900 MPa, which is slightly lower than diamond. However, its heat resistance (1400℃) is almost double that of diamond (800℃). Due to the poor thermal stability of diamond grinding tools, it should be used with speed limit, and the thermal stability of CBN abrasive grains is good, so CBN grinding wheels can be used

Cermet is an important tool material that includes non-metallic refractory composites (ceramics) and metal bond with lower melting point. Diamond wheels grind cermet. They can be economically ground with  diamond wheels , so the range of applications continues to expand. In Europe and the United States, all carbonitride-containing materials are generally considered to be cermets. In Japan, cermets refer only to those materials that contain titanium carbide. As a tool, it must have toughness and wear resistance at high temperatures. Early cermets were very hard but quite fragile, and modern cermets enhanced toughness and reduced hardness. The hardness mainly depends on the titanium nitride and titanium carbide content. The properties of these composites with the binder phase affect their grindability. The temperature of grinding cermet is higher than that of grinding tungsten carbide, and the grinding force is larger, especially the normal grinding force. Diamond wheels grind cerme

Straight-line beveling grinding of glass and mirrors is widely used in the architectural and glass furniture industries. The completion of the straight line bevel grinding production process for glass and mirrors is inseparable from the diamond grinding wheel. Studying and analyzing various elements of the diamond grinding wheel for beveling glass grinding the beveled glass are significant for saving energy and improving efficiency in deep processing of glass. The process of beveling glass grinding with diamond wheels is very complicated. During the grinding of the glass by the diamond wheel, the diamond abrasive grains are irregularly distributed on the surface of the grinding wheel. The manufacturing precision of the diamond grinding wheel itself also affects the end face runout and radial runout during beveling glass grinding process, which will affect the surface roughness of the glass. High-strength diamonds are indeed effective in increasing the sharpness of diamond wheels. In

Ceramic materials are widely used in tools, automotive, aerospace, electronics, communications (fiber), medical and other industries. The market demand for ceramic materials is continuing to rise. The only obstacle is the processing cost. Sometimes processing costs account for 80%-90% of the total manufacturing costs. In order to obtain good surface roughness, ideal non-destructive surfaces and sub-surface layers, the machining of ceramic workpieces requires careful design and implementation of the grinding process to increase production efficiency, surface layer accuracy, finish and surface quality. Double face grinding is one of the most effective methods for finishing flat end faces. The main purpose is to achieve high removal rates and avoid surfaces or tissue damage to meet fine quality requirements. However, high drive power, large noise, and rapid passivation of the grinding wheel and clogging of the air holes inhibit the application of the double face grinding. Unlike conven

Ceramic materials have many excellent properties such as high hardness, high wear resistance, corrosion resistance, heat resistance, heat insulation, low density and low expansion coefficient, and strong chemical inertness. They are widely used in precision bearings. Automotive components, biomimetic compatible implants, sealing components, refractory materials, cutting tools and electronics. However, due to the low plasticity of the ceramic material, if the processing method is improper, it is easy to cause brittle failure and microcracks, making the processing of the ceramic material very difficult. Therefore, researchers at home and abroad have studied the processing mechanism and processing technology of ceramic hard and brittle materials. It is believed that although the resin bond diamond wheel has higher price and lower grinding efficiency, the application of superabrasive abrasive for direct contact removal processing as the representative grinding technology is still one of t

High surface quality and low surface damage are necessary for processing of various hard and brittle materials such as stone, glass, ceramics, semiconductor materials and optical crystals, etc. Therefore, various high-performance precision diamond grinding wheel is required for precision grinding. However, when the particle size of the diamond is reduced to a certain extent, the manufacture of the precision diamond grinding wheel has great difficulties, including the dispersion of the diamond, the selection of the bond, and the structural design of the grinding wheel, which are different from the ordinary grinding wheel. Similarly, the dressing of precision diamond grinding wheels and the grinding mechanism of different hard and brittle materials have also received extensive attention. The abrasives used in precision diamond grinding wheel are all ultra-fine diamond powder. Due to the action of static electricity, agglomeration occurs in the manufacturing process of the grinding w

The excellent grinding performance of vitrified bond CBN grinding wheel is related to many grinding factors, such as grinding wheel characteristic parameters, grinding parameters, grinding fluid and the dressing method of grinding wheel. Among them, the grinding wheel dressing method plays a key role. If the grinding wheel is not well dressed, the ground metal will be bonded to the surface of the grinding wheel, resulting in large grinding force, high grinding temperature and increasing wear of the grinding wheel. The vitrified CBN grinding wheels should be trimmed at high speed with cup shaped diamond wheels. Generally, single-grain diamond or diamond pen trimming is used, and silicon carbide grinding wheel is also used to trim vitrified bond CBN grinding wheel. Although it is easier to implement a  ceramic CBN grinding wheel  with single diamond, there are many problems. Due to the high hardness of the grinding wheel itself, the single diamond is easily passivated compared with

In the process of glass grinding, in order to get a good edging quality, we must choose a good diamond grinding wheel for glass grinding. Then we should choose appropriate grinding speed according to the edge grinding requirements. So we could get the desired effect under the action of a certain pressure of coolant. The diamond grinding wheel consists of four parts depending on its diamond bond specification including mesh, diamond type, diamond content and binder. Each part is a specific effect exhibited by grinding wheel in a particular application. The mesh size is related to the size of the diamond. The mesh number is defined as the number of meshes per square inch of mesh. The mesh size is always between the two mesh ranges. Adhesive materials are a key part of the overall performance of diamonds. It is a metal matrix in which diamond is dispersed. At present, the diamond grinding wheel matrix include copper matrix, aluminum matrix and steel matrix. The steel matrix grindin

Polycrystalline diamond (PCD) is a polycrystalline crystal obtained by mixing diamond micronized powder of micron size with a small amount of metal powder (such as cobalt) and sintering at high temperature (1400 ℃) and high pressure (6000 MPa). Compared with other tool materials, PCD has the characteristics of extremely high hardness and wear resistance, high thermal conductivity, low thermal expansion coefficient, low friction coefficient, fast heat dissipation, low cutting temperature, low thermal deformation, and reduced surface roughness. However, PCD has a strong affinity with iron elements, so it is not suitable for processing ferrous metals. The common sharpening processes for PCD cutter include diamond grinding wheel mechanical sharpening, electric discharge sharpening, electrolytic sharpening, etc. Among them, the diamond grinding wheel mechanical sharpening is the most mature technology and it is the most widely used at present. This method has low sharpening efficiency an

The vitrified bond diamond grinding wheel is a grinding tool which is made by mixing ceramic or glass as bond with diamond abrasive. The diamond abrasive and ceramic or glass are firmly bonded through molding process and heat treatment process. A variety of new materials continue to emerge with the development of science and technology. In a sense, the level of mechanical processing restricts the full use of new materials. Machining is evolving in the direction of high efficiency, high precision, low loss, and automation. Ceramic bond diamond grinding tools are the product of this development. The application range is more and more extensive, and the number of applications is increasing year by year in the world. Diamond grinding tools are mainly used for cutting, grinding or polishing of cemented carbide, ceramic and refractory materials, glass, graphite, gemstones, non-ferrous materials and non-metallic materials, etc. The use of  ceramic bond diamond grinding wheels  in sharp
