(1) The processing method of grinding a very thin layer of metal from the surface of a workpiece using grinding tools and abrasives is called grinding.

(2) Grinding is a method of precision machining of workpieces. The main function of grinding is to achieve high dimensional accuracy, shape accuracy, and minimal surface roughness of the workpiece.

Grinding treatment is a very important sub process in surface treatment technology. It has a wide range of applications in the industry.

Grinding treatment refers to the precision machining (such as cutting) of the machined surface by coating or pressing abrasive particles onto the grinding tool, and by relative motion between the grinding tool and the workpiece under a certain pressure. Grinding can be used to process various metal and non-metal materials. The available machining surface shapes include flat, inner and outer cylindrical and conical surfaces, convex concave spherical surfaces, threads, tooth surfaces, and other contours. The processing accuracy can reach IT5-01, and the surface roughness can reach Ra0.63-0.01 μ m.

Grinding, using coarse-grained grinding wheels to quickly process expanding surfaces or outer circles until the desired size is obtained.

Grinding, refining and resting the product to achieve the desired surface finish of the workpiece.

In a word, it's the difference between rough grinding and fine grinding.
