But  the mill should be lower face painting and coating ability to wait underlying paint layer after complete dry mill, otherwise it is easy to paint  stone drill bits white, absorbent substrates without some initiative mill, in order to protect the disc with sandpaper quality of work, before grinding to polishing tools should be tested.
 Sandpaper in subsistence use of all sizes are too hearty, whether it is plastic industry, metal industry, construction industry or the automotive industry are operating very widespread. Request for the operation of various industries in each sandpaper does not vary, some  characteristics comply with grinding tools, and some sandpaper to comply with  tile cutting blades the shape, material characteristics, such as differences optional sandpaper.

 Sand may be divided into two types of discs, and the non-porous perforated disc sandpaper sandpaper disc, a perforated disc sand to facilitate the discharge of waste in the grinding object debris carbide drill bits  from the hole, advance grinding efficiency. If the disc sand sticking to the speed change master disc, the special operating machinery or hand, using sandpaper polished, mostly for hard and brittle paint kind of grinding, end compared with convenient operation, but disc sand in operation The process will produce a lot of dust, affecting the health scene, which is dominated disc sand to prevent a fragmentation weaknesses problems.
