Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding disc technology, and more specifically, to a combination grinding disc with elastic stretching. Background Technology
[0002] A grinding disc is a tool used for surface treatment operations such as grinding and polishing. It is mainly used to remove a large amount of excess material from the surface of a workpiece. Its abrasive particles are relatively large, resulting in a high surface roughness after grinding. Grinding discs can quickly remove gating marks and oxide scale from the surface of castings, preparing them for subsequent finishing.
[0003] A search revealed that Chinese patent CN212683551U discloses a grinding disc. Addressing the current problems of high rigidity in grinding discs, which easily lead to brittle fracture during grinding with the housing, and the difficulty in evenly coating the adhesive onto the film surface, resulting in uneven stress on the grinding disc and uneven surface roughness, the patent utilizes a flexible layer capable of elastic deformation. During grinding, the abrasive layer presses against the surface of the housing, and the elastic deformation of the flexible layer absorbs the impact force from the housing on the grinding disc, providing excellent buffering and preventing brittle fracture of the grinding disc.
[0004] During prolonged use, the surface of the grinding disc may become damaged. Since the grinding disc is a single unit, it can only be replaced as a whole. It is inconvenient to disassemble and replace only the damaged parts, resulting in excessively high replacement costs. Utility Model Content
