The process of grinding wheel dressing is a kind of grinding between two abrasive products. Not only the thickness of grinding wheel will be decreased, dressing wheel's thickness will also drop, which is the result of combined action. Therefore, it can determine the compensation method for wheel dressing after multiple test. Because the ...

A grinding wheel is used for various types of abrasive cutting (grinding) and abrasive machine operations. In other words, a grinding wheel is used to polish a surface or cut a material. A grinding wheel is generally made from a matrix of coarse particles that are bonded and pressed together in order to form a circular, solid shape.
