[0002] Grinding is a type of surface modification technology. It generally refers to a processing method that uses rough abrasive objects (such as sandpaper containing higher hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness.

[0003] For example, the patent document with application number 202320230876.X discloses a flexible grinding and polishing belt wheel, wherein a connection assembly is provided in the middle of the elastic support body, and a plurality of abrasive belt sheets are provided on the elastic support body, and the plurality of abrasive belt sheets are arranged in an array with equal spacing, and adjacent abrasive belt sheets are arranged in a staggered stack, wherein the portion of two adjacent abrasive belt sheets in contact with the circumferential surface of the support body below the stacking area is the supporting working surface, and the abrasive belt portion of the abrasive belt sheet above the stacking area is the grinding working surface, and the size of the connection between the abrasive belt sheet and the circumferential surface of the support body is H. This utility model is a flexible grinding and polishing belt wheel: good grinding effect.
