How to choose a grinding wheel for abrasives? abrasive manufacturer The general principles for selecting the hardness of the grinding wheel are:
1 When processing soft metals, in order to prevent the abrasive from falling off prematurely, a hard grinding wheel is used.
2 When processing hard metals, in order to make the dull abrasive grains fall off in time, so as to expose new abrasive grains with sharp edges and corners, use a soft grinding wheel.
The former is because when grinding soft materials, the working abrasive of the grinding wheel wears very slowly and does not need to be detached too early; the latter is because when grinding hard materials, the working abrasive of the grinding wheel wears faster and requires faster renew.
When fine grinding, in order to ensure the grinding accuracy and roughness, a slightly harder grinding wheel should be selected. When the thermal conductivity of the workpiece material is poor, and burns and cracks are easy to occur, the selected grinding wheel should be softer.
