Release time:
2023-11-14
In the category of high-precision trainers, according to the different levels of accuracy, divided into three grades: Precision of 3~0.3 μm, roughness of 0.3~0-03 μm called precision machining; Precision of 0.3~0.03 μm, roughness of 0.03~0.005 μm called ultra-precision machining, or sub-micron processing; The accuracy is 0.03 μm(30 nm), and the roughness is better than 0.005 μm or more, which is called nano (nm) processing. The most widely used ultra-precision machining processes are turning, grinding, grinding, throwing and so on.
