It is commonly used in portable polishing machines and sanding machines, and is an increasingly popular running light litter box. The grinding quality is stable and does not burn workpieces, especially for sheet metal of small specifications or stainless steel that needs polishing. These new litter box are not only strong but also safe. Since there is no back base disk, it can also be directly used on the machine. It is divided into grid page plate, high-strength plastic cover page plate and steel paper page plate, which are widely used in automobile manufacturing, shipbuilding, mold, instrument, instrument, medical equipment and Other Grinding, polishing, trimming and other technological processes. Rust removal, high efficiency of modification and polishing, and can be consistent with various complex surfaces. It is mainly used for manual machine polishing more flower-shaped grinding pieces. It is heat dispersion good and is not easy to burn out the workpiece, self-generated air-cooling effect (also known as fan effect) prevents thermal deformation and can work continuously; High derusting, modification and polishing efficiency; Stable grinding. It is widely used in grinding, polishing, trimming and other technological processes of stainless steel welding and grinding, automobile manufacturing, heavy machinery vehicles, shipbuilding, abrasive tools, instruments, medical equipment, etc., deburring, derusting, welding seam and corner grinding, etc.
