As we all know, grinding is the smoothing and precision machining of the surface of the part. The abrasive particles coated or pressed on the grinding tool are used to complete the processing through the relative movement of the grinding tool and the workpiece under a certain pressure. Some people think that grinding and polishing are the same, but grinding and polishing are two different processing methods. Compared with polishing, the surface finish achieved by grinding is lower. Let’s first introduce the classification of grinding. This article introduces the characteristics of grinding. For more knowledge, please pay more attention to our website dynamics.

1. According to the use conditions of abrasives, grinding can be divided into three categories, namely dry grinding, wet grinding and semi-dry grinding. Dry grinding can achieve high machining accuracy and low surface roughness, but the grinding efficiency is low, and it is generally used for fine grinding. The metal removal rate of wet grinding is high, which is more than 5 times higher than that of dry grinding, but the geometry and dimensional accuracy of the machined surface are not as good as those of dry grinding, and are mostly used for rough grinding and semi-rough grinding. And semi-dry grinding can be used for coarse and fine grinding.

2. According to the shape of the machined surface, grinding can be divided into plane grinding, outer grinding, inner hole grinding, spherical grinding, thread grinding, forming surface grinding, meshing surface contour grinding, etc.

3. According to different operation methods, grinding can be divided into manual grinding and mechanical grinding.
