Metal bonded diamond grinding wheel machining ceramics, rough surface

Copper bonded diamond grinding wheel for ceramic tile trim, have a longer life, less prone to crimping ceramic defects, but trimmed smoothness over resin bond diamond wheel differential. Metal bonded synthetic diamond powder  wheel machining ceramics, rough surface, chipping, chipping serious, product processing quality is not high. Resin bonded diamond tools typically phenolic resin and polyimide as a binding agent, has a good cutting tools characteristics of smoothness, but the common drawback is poor in heat resistance is not durable in the preparation and use of the process on the environment and operate personnel hazards; polyimide heat resistance than phenolic resin, but its price is higher, the high cost of preparing diamond tools, and more for large feed coarse carbide and other materials.
