Corundum abrasive life, we all hear the two techniques of grinding and polishing, but we don't know the difference. Now, let's talk about the difference between grinding and polishing with the manufacturer of Corundum Abrasive .
Grinding uses abrasive particles coated or pressed into the lap to perform finishing operations (such as cutting) on the machined surface by relative movement of the lap and the workpiece under a certain pressure.
Grinding can be used to process a variety of metal and non-metallic materials, the surface shape of the processing is flat, inner and outer cylindrical and conical surfaces, convex, concave spherical, thread, tooth surface and other profiles.
The processing precision can reach IT5~01, and the surface roughness can reach Ra0.63~0.01 microns.
Polishing is the processing method that uses mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright, flat surface.
The main difference between the two is that the surface finish achieved by polishing is higher than that of grinding, and chemical or electrochemical methods can be used, while the grinding is basically only mechanical, and the abrasive grain size used is thicker than that used for polishing. That is, the size is large. Manufacturers Share The Difference Between Grinding And Polishing
