How to Use Diamond Wheels to Grind Cermet?

图片
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 whee...

Analysis about Diamond Wheel for Glass Beveling Grinding

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...

Grinding Mechanism Research about Precision Diamond Grinding Wheel

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 p...

Diamond Grinding Wheel and Glass Grinding Technology

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...

How to Choose Diamond Grinding Wheel for PCD Tools

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...
