Vitrified bond diamond grinding wheel

The vitrified/ceramic bond diamond grinding wheel has high strength, good heat resistance, sharp cutting and high grinding efficiency. And it is not easy to generate heat and blockage during the grinding process. There is small thermal expansion to control the processing accuracy. Compared with the resin bond grinding wheel, it solved the problem of the resin diamond grinding wheel's lower life, low grinding efficiency and the problem of deformation of the grinding tool during the grinding process. Due to the vitrified bond grinding wheels have above advantages, it was immediately widely used in wafers (semiconductor wafers and solar wafers), diamond compacts, diamond polycrystalline, diamond tools, cubic boron nitride, tungsten steel ( Cemented carbide), new engineering structural ceramics, gemstones, crystals, rare earth materials (magnetic materials) and other high-hard and brittle materials, and also have achieved good economic benefits.

Overview of vitrified bond abrasive grinding wheels

It is a kind of abrasive grinding tool with many holes and cutting with abrasive particles after compacting, drying, roasting and finishing with ceramic binder. The sharp corners of the abrasives exposed on the surface are used as cutting edges. It is mainly divided into two categories: ceramic grinding wheels (silicon carbide, corundum etc.) and ceramic superhard abrasive grinding wheels (ceramic bond diamond grinding wheels and ceramic bond CBN grinding wheels).

Advantage of ceramic bond diamond and CBN grinding wheel:

1. High grinding efficiency;

2. High wear resistance of the grinding wheel, lower abrasive consumption, especially when grinding hard and brittle workpieces;

3. The grinding force is small and the grinding temperature is low;

4. The workpiece has high precision, good surface quality and good shape retention.

Therefore, the ceramic bond diamond grinding wheel has more and more advantages in the grinding of some special materials such as diamond, industrial ceramics, diamond compact, diamond polycrystalline, diamond and CBN tools, cemented carbide and other high-hard and brittle materials. It has more and more obvious advantages and a good prospect in the development of diamond abrasive tools. It is considered to be a high-performance abrasive tool with high speed, high efficiency, high precision, low grinding cost, and low environmental pollution. It has more and more wide range of applications and is a hot spot for research and development of grinding tools in various countries around the world.
