Grinding tools are widely used in the machinery industry, construction industry and other industries, abrasive tools generally have self-sharpness
Abrasives tools are tools used for grinding and polishing. Most Abrasives tools use artificial abrasive, and of course natural abrasive extracted directly from mineral rocks.
That is, due to grinding, part of the grinding tool broken or binder fracture, abrasive part off, will expose new sharp abrasive, so that the abrasive continues to maintain sharp cutting performance.
