Grinding wheel ten principles

 Wheel selection is often based on the three factors for the choice of grinding wheel: 1. Roughness; 2, life requirements; 3, the grinding efficiency requirements. Roughness is determined by the abrasive particle size, can be determined according to the roughness of the abrasive wheel size selection; life requirements and according to the requirements of grinding efficiency grinding wheel hardness can determine the cup grinding wheels  size and organizational good. We summarize a bit, wheel choices about ten principles.
1, the selection of coarse grained, fine grinding select granular.
2, sheet wheel should choose rubber or resin bond.
3, when the grinding and shaping grinding wheel hardness should be higher.
4, wheel fine grain size, the grinding wheel hardness should be lower.
5, form grinding, precision grinding should take the wheel tighter organization.
6, the diamond grinding wheel  workpiece grinding area is large, you should choose loose tissue of the wheel.
7, grinding nonferrous metals and other soft materials should be selected soft and loose wheel, grinding wheel in order to avoid congestion.
8, workpiece material hardness, should choose soft wheels, low hardness of workpiece material should be selected hard wheel.
9, grinding steel and  diamond cbn wheel other ductile material should be selected corundum abrasives; grinding cast iron, tungsten carbide and other brittle materials should be selected silicon carbide abrasive.
10, the grinding contact area should choose soft wheel. Therefore, internal grinding and face grinding wheel hardness than cylindrical grinding wheel hardness is low.
