Definition of precision machining and ultra-precision machining(图1)

Precision machining refers to a machining process that achieves a high degree of machining accuracy and surface quality during a certain period of development. At present, precision machining refers to a machining technology with a machining accuracy of 1 ~ 0.1μm and a surface roughness of Ra0.1 ~ 0.01μm.

Ultra-precision machining refers to a machining process that achieves the highest degree of machining accuracy and surface quality in a certain period of development. Obviously, in different development periods, precision and ultra-precision machining have different standards.

At present, ultra-precision machining refers to the processing technology that the dimensional accuracy of the processed parts is greater than 0.1 μm, the surface roughness Ra is less than 0.025 μm, the resolution and repeatability of the machine tool positioning accuracy is greater than 0.01 μm, also known as sub-micron processing technology, and Development of nano-scale processing technology.
