Diamond tool ultra precision machining technology is an ultra-precision machining technology an important part of many national defense products parts (such as gyroscopes, a variety of flat and curved mirrors and lenses, precision instruments and high-power laser systems more kinds of parts, etc.) require the use of ultra-precision diamond-cutting to processing.

     Single crystal diamond tool ultra precision cutting in the ultra-precision machine tools, can be processed to a high mirror finish. Ultra-precision cutting cutting thickness can be extremely small, the minimum thickness can be cut to 1nm. Single crystal diamond ultra-precision cutting tool used requires extremely sharpened edge, edge radius at 0.5 ~ 0.01μm. Because very small edge radius, the cutting edge of the last measurement is extremely difficult, it is now available atomic force microscope (AFM) measurements easily.
