The purpose of ultra-precision in order to process the ultra-smooth plane
Environmental ultra-precision need constant temperature vibration, anti-electromagnetic interference and other conditions
Ultra-precision tools on the use of natural single crystal diamond, ordinary high-speed steel or carbide
Ultra-precision machine tools to use ultra-high precision machine tools, micro-feed agencies, pneumatic and hydrostatic guide and other devices
Technology, ultra-precision mainly for follow-up processing, finishing.
