Study on Ferrite Ceramics Ground by Resin Bond Diamond Wheel

图片
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 technolog...

Diamond Grinding Wheel and Glass Grinding Technology

图片
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

图片
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...
