Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a grinder which is easy to assemble. Background Art

[0002] A grinder is a machine that uses a grinding tool coated with or embedded with abrasives to grind the surface of a workpiece. It is mainly used to grind high-precision planes, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in the workpiece, and is used for single-sided grinding or polishing of materials. A surface grinder is a precision grinding and polishing equipment. The material to be ground is placed on a flat grinding disc, which rotates counterclockwise. The correction wheel drives the workpiece to rotate, and gravity or other means are used to apply pressure to the workpiece. The workpiece and the grinding disc rotate relative to each other to achieve the purpose of grinding and polishing.

[0003] During the grinding process of the surface grinders currently on the market, the flatness of the grinding disc will decrease. In order to ensure the fineness of the workpiece surface, the grinding disc needs to be trimmed regularly. The grinding discs on the market require special tools to be disassembled and assembled, which causes users to waste a lot of time when using them. Utility Model Content
