The flatness of the grinding disc is the benchmark for grinding and the guarantee of obtaining a precise workpiece plane. During the grinding process, the flatness of the grinding disc will decrease. The main reason is that the internal and external linear speeds of the grinding disc are different and the wear is inconsistent. The grinding disc needs regular trimming. There are two dressing methods: 1. Use a reference plane electroplated diamond dressing wheel to trim the surface. Since the electroplated diamond dressing wheel basically does not wear, a higher flatness can be obtained. 2. After trimming through the trimming mechanism, better flatness can also be obtained. The principle of trimming is consistent with that of a lathe. The grinding disc rotates, and a knife that can move forward and backward is driven by the tool bar to grind and obtain a flat surface.

The main types of grinders include disc grinders, shaft grinders and various special grinders. The grinding machine control system uses PLC as the control core, and the text display is the control method of the human-machine dialogue interface. The human-machine dialogue interface can communicate with people about equipment maintenance, operation, faults and other information; the operation interface is intuitive and convenient, program controlled, and simple to operate. Comprehensive safety considerations are taken into consideration, and misuse due to abnormal conditions will be invalid. Real-time monitoring, fault and error alarms, and easy maintenance. Grinding is a finishing process (such as cutting) that uses abrasive particles coated or pressed on the grinding tool to perform relative movement between the grinding tool and the workpiece under a certain pressure. processing). Grinding can be used to process various metal and non-metal materials. The surface shapes processed include planes, inner and outer cylindrical and conical surfaces, convex and concave spherical surfaces, threads, tooth surfaces and other profiles. The processing accuracy can reach IT5~01, and the surface roughness can reach Ra0.63~0.01 micron, which is fine

According to the number of grinding discs, it can be divided into: single-sided grinding machine and double-sided grinding machine.

According to the size of the grinding disc, it can be divided into: 380 grinding machine, 460 grinding machine, 610 grinding machine, 910 grinding machine, etc.
