[0002] An abrasive brush is a tool used for surface treatment, usually composed of bristles, brush plates or abrasives. The background technology involves multiple fields such as material science, mechanical engineering, and manufacturing processes. The bristles of an abrasive brush are usually made of various materials, including metal wire, nylon, abrasives, etc. The choice of material depends on factors such as the object of grinding, the requirements of surface treatment, and the use environment. The process of manufacturing an abrasive brush includes material processing, molding, fixing, heat treatment, and other links. Excellent manufacturing technology can ensure that the abrasive brush has consistent quality and performance, and improve its service life and stability. Publication number: CN213828504U discloses an abrasive brush, including: a clamping handle, a placement hole and a fixing hole are provided on the clamping handle, the placement hole is arranged on the side wall of the clamping handle, and the fixing hole is arranged at the end of the clamping handle; an abrasive wire, the abrasive wire is arranged in the placement hole; a fixing member, the fixing member is connected in the fixing hole, and the bottom of the fixing member abuts against the abrasive wire. The technical solution of the utility model comprises a clamping handle, a grinding wire and a fixing part to form a special grinding brush for deburring the inner cavity side wall groove of the workpiece, thereby improving work efficiency. However, for the above-mentioned equipment, after the equipment is used for a long time, the grinding brush may be worn, resulting in a decrease in grinding efficiency.
