Mechanical parts processing has many advantages. Previously, we have also shared with you the specific advantages of mechanical parts processing. The most obvious one is that it can achieve a high precision that ordinary processing cannot reach. This high precision also depends on precise processing equipment and an accurate control system. A precision mask is used as an intermediate to achieve extremely fine control over the amount of material removed or added from the outer surface. So, what are the characteristics of mechanical parts processing? Now, let me introduce it to you in detail:
1. Precision Part Cutting Processing
It mainly includes precision turning, mirror grinding, and lapping, etc. On a precision lathe, a single-crystal diamond tool that has been finely ground is used for微量车削 (micro turning). The cutting thickness is only about 1 micron. This method is often used to process high-precision parts with a highly smooth surface, such as spherical, aspherical, and planar mirrors made of non-ferrous metal materials.
2. Mechanical Parts Processing
When the processing precision of mechanical parts is aimed at the nanometer level, and even ultimately at the atomic unit level, the ultra-precision part cutting processing method can no longer meet the requirements. It is necessary to resort to the processing methods of special mechanical parts, that is, using chemical energy, electrochemical energy, thermal energy, or electrical energy, etc., to make these energies exceed the bonding energy between atoms, thereby removing the adhesion, bonding, or lattice deformation between some atoms on the surface of the workpiece, so as to achieve the goal of ultra-precision processing. Processing methods belonging to this category include mechanical-chemical polishing, ion sputtering and ion implantation, electron beam exposure, laser beam processing, metal evaporation, and molecular beam epitaxy, etc.
