Description

TECHNICAL FIELD

[0001] The application relates to the technical field of polishing grinding devices, in particular to a membrane wall tube screen automatic polishing machine. BACKGROUND

[0002] The polishing machine is also called a grinding machine and is often used for mechanical grinding, polishing and waxing. The working principle is that a motor drives a sponge or wool polishing disc installed on the polishing machine to rotate at a high speed. Through the joint action of the polishing disc and polishing agent and the friction with the surface to be polished, the polishing disc can remove paint surface pollution, oxidation layer and shallow marks. The rotating speed of the polishing disc is generally 1500-3000 r / min, and is mostly stepless speed regulation. During construction, the speed can be adjusted at any time according to the needs.
