Diamond Grinding Wheel Used for Double Face Grinding of Alumina Ceramic

图片
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 f...

Application of Vitrified Bond Diamond Grinding Wheel for PCD Tools Sharpening

图片
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 ...
