Sharpening Handbook

Grinding introduces cracks in carbide, and can make it more brittle. It is best to use low grit grinding up to the final angle, and then switch to a high grit grinding for finishing the grinding. Shaping the tool - a process for gross removal of metal to change the shape of the cutting edge. This is something not done often, so it is listed 3 rd. Some other useful information can be

Beveling of Silicon Carbide Wafer by Plasma Chemical

Beveling is essential for preventing the chipping of the edge of a wafer during surface polishing and other processes. Plasma chemical vaporization machining (PCVM) is an atmospheric-pressure plasma etching process. It has a high removal rate equivalent to those of conventional machining methods such as grinding and lapping, which are used for high-hardness materials

As the SiC market moves from 150

Metallographic Abrasive Grinding

Silicon Carbide SiC is a manufactured abrasive produced by a high temperature reaction between silica and carbon. It has a hexagonal-rhombohedral crystal structure and has a hardness of approximately 2500 HV. It is an ideal abrasive for cutting and grinding because of its hardness and sharp edges. It is also somewhat brittle, and therefore it

6 Problems That Can't be Ignored in Tool Grinding | MachineMfg

However, carbide tools are high in hardness and brittle, sensitive to collisions, and easy to break the cutting edge. Therefore, during the grinding process, care must be taken in the handling and placement of carbide tools to prevent collisions between the tools or the falling of the tools. Because the precision of high-speed steel tools is relatively low, their grinding requirements
