Polishing machines, also known as grinders, are often used for mechanical grinding, polishing and waxing. Polishing machine equipment is widely used in machinery manufacturing, military aerospace, ships, electronic parts, instruments, light industry, watch parts, textile equipment parts, auto parts, knitting machine parts, bearing industry, medical equipment, precision parts, powder Metallurgy, 3D printing, metal stamping sheets, handicrafts, tools and other industries.

The working principle of the polishing machine is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and friction with the surface to be polished, the paint surface pollution, oxide layer, and shallow surface can be removed. purpose of scars. The speed of the polishing disc is generally 1500-3000 r/min, mostly stepless speed change, which can be adjusted at any time during construction.

According to the power source, there are two types of polishing machines: pneumatic and electric, and according to the function, there are two types: dual-function industrial sanding/polishing machine and simple polishing machine. There are three kinds of high-speed polishing machines, medium-speed polishing machines and low-speed polishing machines according to the speed classification. The main accessory of the polishing machine is the polishing disc. The polishing disc is installed on the polishing machine and works together with the abrasive or polishing agent to complete the grinding/polishing operation. According to the connection method between the polishing disc and the polishing machine, bolt disc, nut disc and suction cup. Polishing discs can be divided into wool polishing discs, sponge polishing discs and rabbit fur polishing discs according to their materials
