Tungsten Carbide Cutting Tools Grinding Features

Tungsten carbide cutting tools inherited high hardness, brittleness, thermal conductivity and other characteristics of tungsten carbide materials, making tungsten carbide cutting tools grinding have great difficulty. Tungsten carbide cutting tools grinding features can be concluded in two aspects.

First, tungsten carbide cutting tools grinding features reflects in that tungsten carbide cutting tools grinding process requires a better self-grind resistance and good cooling, so as to reduce the production of grinding cracks.

Second, tungsten carbide cutting tools grinding features reflects in that diamond grinding wheels are widely used in tungsten carbide cutting tools grinding due to high grinding efficiency, small grinding force, easy to passivation and lower local temperature grinding surface contact area ( generally at 400 ℃ for around), etc.. But in the diamond grinding wheel process of tungsten carbide cutting tools, due to large grinding allowance, processing methods, diamond tools and grinding systems feature if choose unproperly, will result in instantaneous temperature of tool grinding surface is too high , resulting in grinding cracks.
