Precision hardware parts processing refers to the processing of some small diameter hardware parts.

1. Cutting and processing of precision hardware parts

Mainly include precision turning, mirror grinding and grinding. Micro turning is performed on a precision lathe with a finely ground single crystal diamond turning tool. The cutting thickness is only about 1 micron. It is usually used to process high-precision and smooth surface parts, such as spherical mirrors, aspheric mirrors and flat mirrors made of non-ferrous metal materials.

2. Precision hardware parts processing

When the machining accuracy of precision parts is nanometers or even atomic units (atomic lattice distance is 0.1-0.2 nanometers), the processing methods of ultra-precision parts cannot be adapted. It is necessary to use special precision parts processing methods, namely chemical energy, electrochemical energy, thermal energy or electric energy, to make these energy exceed the bonding energy between atoms, so as to eliminate the adhesion, bonding or lattice deformation of certain atoms on the surface of the workpiece, so as to achieve The purpose of ultra-precision machining. Such processes include mechanical chemical polishing, ion sputtering and ion implantation, electron beam exposure, laser beam processing, metal evaporation and molecular beam epitaxy.
