Ultra-precision machining technology is a kind of modern machining technology with extremely high machining accuracy. Details are as follows:
1, its machining accuracy can reach the nanometer level (1 nm = 0.001 micron), the surface roughness can also reach the nanometer level. This technology is widely used in precision instrument manufacturing, electronics, aviation, aerospace and other industrial fields. Ultra-precision machining technology can be broadly divided into two categories, namely, ultra-precision cutting and ultra-precision special machining.
2. Ultra-precision cutting processing includes ultra-precision turning, mirror grinding, lapping, etc., while ultra-precision special processing includes mechanical-chemical polishing, electron-beam exposure, laser-beam processing, ion-sputtering and ion-implantation, metal vapor deposition and molecular beam epitaxy. These technologies and other high-tech to promote each other, *** with the development, especially their integrated development, more and more attention.
