Abrasive is a kind of high hardness non-metallic crystal. It can not only grind copper, aluminum, cast iron, and other soft materials but also can grind a variety of hardened hard steel, high-speed steel, and hard alloy and other hard materials.
After dressing the working face of the grinding wheel, can form a very fine cutting edge to cut off the extremely thin metal layer on the surface of the workpiece. And grinding also has a very high metal removal rate, such as through strong grinding, a cut of 2~20mm metal.
Grinding can obtain extremely high machining accuracy and extremely low surface roughness. With mirror grinding, the surface roughness of the workpiece can be up to ra0.01um, the surface of the workpiece is as smooth as a mirror, the size accuracy and shape accuracy can up to 1um, and the error is equivalent to 1/70 or less of the thickness of a person's hair. When grinding the grinding wheel, some blunt grinding grains can automatically fall off or break under certain conditions, exposing new sharp grains to participate in the grinding process. This feature is called the "self-sharpening" of the grinding wheel, which can keep the grinding performance of the grinding wheel good.
