Description

Technical Field

[0001] The utility model relates to the technical field of polishing cloth wheels, in particular to a wear-resistant polishing cloth wheel. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media. In order to improve the efficiency of polishing, processing plants use automated equipment instead of manpower to polish workpieces. When polishing small parts with many curved surfaces, it is necessary to use a polishing cloth wheel for polishing, so that the direction of rotation of the polishing wheel faces the operator and has achieved sufficient speed.

[0003] However, in the process of using the polishing cloth wheel, we found that the existing polishing cloth wheel has poor wear resistance and short service life. At the same time, the existing polishing cloth wheel is mostly installed on the corresponding motor shaft in a threaded manner, which is easy to cause radial runout during use and cause damage. Therefore, we propose a wear-resistant polishing cloth wheel. Utility Model Content
