precision processing classification

 precision machining has special requirements for workpiece materials, processing equipment, tools, measurement and environmental conditions. It requires comprehensive application of precision machinery, precision measurement, precision servo system, computer control and other advanced technologies. The precision of ultra-precision machining is more than one order of magnitude higher than that of conventional precision machining. In addition to the need for new machining methods or new machining mechanisms, special materials are available for workpiece materials, processing equipment, tools, measurement and environmental conditions. Claim.
precision special processing is nanometer. When the atomic unit (atomic lattice distance is 0.1~0.2 nm) is the target, the cutting method can not be adapted. It needs special processing method, namely application of chemical energy and electrochemistry. Energy, heat or electrical energy, such that the energy exceeds the bonding energy between the atoms, thereby removing the adhesion, bonding or lattice deformation between some of the atoms on the surface of the workpiece to achieve ultra-precision processing.
Among these processes are mechanochemical polishing, ion sputtering and ion implantation, electron beam exposure, laser beam processing, metal evaporation, and molecular beam epitaxy. These methods are characterized by very fine control of the amount of surface layer material removed or added. However, in order to obtain ultra-precision machining accuracy, it is still necessary to use sophisticated processing equipment and precise control system, and use ultra-precision mask as an intermediary.
 Ultra-precision machining mainly includes ultra-precision turning, mirror grinding and grinding. It is micro-turned on a super-precision lathe with a finely ground single crystal diamond turning tool. The cutting thickness is only about 1.5 microns. It is often used for the processing of spherical, aspherical and planar mirrors of non-ferrous materials with high precision and high surface height. Components.
