PCB manufacturing process of grinding method using abrasive brush roller used in the PCB manufacturing process of the brush roller can be divided into two categories according to function, bur automatic grinding machine, namely grinding brush roller and cleaning brush roller, drilling Tsui automatic grinding machine, by the use of the material is divided into nylon pin brush roller, brush roller and ceramic non-woven brush roll three lights, supply automatic grinding machine, they have their own characteristics in use. Nylon pin brush roller by nylon filaments containing abrasive brush needle is divided into different silicon carbide (sic) abrasive type, alumina (ao) class and pure nylon abrasive, non-woven brush roll according to the different non-woven abrasive is divided into silicon carbide , alumina and pure non-woven class. Advanced processing and manufacturing and photonics industry is China's characteristic and dominant industries, grinding machines, but also the development of China's key industries, the development of grinding technology in these two industries have an important role. The project developed nanoscale efficient grinding technology has obvious advantages in the processing efficiency, processing costs, processing quality and accuracy, with good prospects.
