The same abrasive grinding wheel
2016-01-14 by bridge
The grinding wheels is cutting tool grinding, porous object which consists of many small and hard abrasive and binder viscosity into. Abrasive directly undertake the cutting work, must be sharp and has high hardness, resistance and certain toughness. Common Abrasive Alumina corundum and silicon carbide are also called two. Alumina abrasive high hardness, good toughness, suitable for grinding of steel material. Silicon carbide abrasive hardness higher, more sharp, good thermal conductivity, but more brittle, suitable for grinding cast iron and hard alloy.
The same abrasive grinding tool, due to their different thickness after machining, the workpiece surface roughness and machining efficiency is not the same, wear particle coarse for rough grinding, fine grinding grain for grinding, abrasive particle size, the smaller the more coarse.
