Grains used for grinding and polishing tools can be broadly divided into 1 general grain and 2 extra-abrasive grain.The materials used can be categorized 1 as alumina and silicon carbide, and 2 as diamond and cubic boron nitride, with further sub-categories according to differences in.
The elastic abrasive can have well-profiled contact with a curved surface workpiece on account of its polymer elastic abrasive binder structure with greater flexibility, which is different from a rigid fixed abrasive grinding wheel where fretting of adjacent abrasives may happen on partial surface.It is beneficial to improve the quality of.
Abrasive grains for both bonded and coated abrasive products are made by graded crushing and close sizing of either natural or synthetic abrasives.Raw abrasive materials first are crushed by primary crushers and are then reduced by jaw crushers to manageable size, approximately 19 millimeters mm 0.
