In grinding, polishing processing nanometer era

As IT related products, automobile, home electrical appliances industry products development, high grinding and polishing processing of increasing importance. For production and technical personnel, high precision and efficiency of automation forever theme. Grinding and polishing technology research achievements of industrial products, promotes the update is developing forward down-to-earth.

(1) grinding, polishing technology increasing importance

Now, almost all the family has spread to personal computer (PC) game (HDD) equipped with past ultra-precision machine monocrystalline diamond cutting tools. In recent years, the disk surface density of annual growth rate was 100% record, every square inch of 1G recording densities. This technique by aluminum base plate after grinding plate, again without electrolysis NIP film by grinding machining make its surface smoothness and implemented. And high-performance processing technology progress, but also makes the base plate material from aluminium alloy replacement for rigid than higher aluminium silicate glass, crystal glass, therefore, grinding, polishing processing importance.

(2) precision

Linear motor started development, because it can realize the processing and attention. But in recent years, the use of linear motor eye has gradually turning precision. And he said, many excellent properties linear motor, high precision of circular interpolation precision particularly impressive. Its reason non-contact drive system is not traditional servo motor rotate with gear reducer, ball screw, etc. Various mechanical coupling caused by error, and the factors of linear motor must adopt sealed control
