The spatial positioning of the composite is the spatial position where the composite is placed on the drill bit. The spatial positioning of the composite chip is the key point of the design of the composite chip bit, which has a great influence on the drilling performance of the bit.

Vitrified diamond grinding wheels are mainly used in the grinding and processing of PCD tools, CBN tools, carbide, cermets, ferrites, cast iron, gemstones, traditional ceramics and new engineering ceramic materials, and can also be used for chromium-quenched steel bearing rollers, Precision grinding of crankshafts of automobiles and tractors, gear necks of hydraulic pumps, etc.

Before grinding, should check the grinding wheel. If the grinding wheel is beating, the cylindrical surface is irregular, and the fillet corner is too large, it needs to be dressed. Generally can use grinding wheel dresser(diamond dresser, dentate dresser) to dress the cylindrical surface of grinding wheel; also can use used grinding wheel with relatively large hardness for dressing. If the grinding wheel profile is not smooth, you can replace the grinding wheel.

Ceramic vacuum chuck is a kind of uniform solid or vacuum body made of nano powder. A large number of connected or closed ceramic materials are produced in the material by sintering at high temperatures.

Cutting tools have sharp cutting edges. Handling them with bare hands may cause injuries

One of the most significant benefits of using indexable tools is that cutting edges can be updated don’t need remove the tool from the production site.

Mirror grinding is a grinding that the surface roughness of the workpiece is Ra< 0.01μm, and the light is like a mirror after grinding, so it can be clearly photographed. The flatness of the grinding surface is not greater than 3μm /1000mm. The surface machining of high precision and high added value parts requires mirror grinding.
