General principle of China high efficient grinding disc selection

For grinding hard materials, China high efficient grinding disc should be used to keep them “self-sharp”, improve the service life of the polishing discs and reduce the grinding heat; when grinding soft materials, hard grinding wheels should be used. Keep the abrasive grain sharp and sharp for a long time, which is good for cutting. Details are as follows:
1. When the grinding toughness is large, the non-ferrous metal workpiece, the high-hardness cutting tool, the grinding thin-walled part and the blocked polishing material should be soft-grinding disc; the mirror-grinding should be super-soft grinding.
2. The workpiece material is the same, longitudinal grinding and plunge grinding, peripheral grinding and end grinding, cylindrical grinding and inner circle, plane grinding, wet grinding in dry grinding, fine grinding in rough grinding, intermittent surface grinding Cutting and continuous surface grinding, etc., the former must use the hard grinding disc than the latter.
3. High-speed, high-precision grinding, steel blank grinding, workpiece deburring, etc., should choose a harder China high efficient grinding disc.
