Description

Burnishing device is used in processing of metal framework of massage armchair

Technical Field

The invention relates to the technical field of metal polishing, in particular to a polishing device for processing a metal framework of a massage armchair.

Background

Polishing refers to a process of reducing the roughness of a workpiece surface by mechanical, chemical, or electrochemical actions to obtain a bright, flat surface. The method is to carry out modification processing on the surface of a workpiece by using a polishing tool and abrasive particles or other polishing media. Polishing does not improve the dimensional accuracy or geometric accuracy of the workpiece, but aims to obtain a smooth surface or a mirror surface gloss, and sometimes also serves to eliminate gloss (matting). Polishing wheels are commonly used as polishing tools. The polishing wheel is generally made of a laminate of a plurality of layers of canvas, felt or leather, both sides of which are clamped by metal disks, and the rim of which is coated with a polishing agent formed by uniformly mixing micro-powder abrasive and grease, etc.
