Precision machining of a workpiece with a processing machine size or performance of the process of change. Be processed according to the temperature of the workpiece in the state, is divided into cold and hot processing. Generally processed at room temperature and does not cause the workpiece chemical or phase changes, called cold. Generally higher or lower than room temperature processing, the workpiece can cause chemical or phase changes, said thermal processing. Cold processing method according to the difference between the pressure can be divided into cutting and processing. Thermal processing common with heat treatment, forging, casting and welding.

Electronics and optical technology, which greatly promoted the freedom of non-spherical geometry, and other non-traditional application of micro-structure of optical components. The emergence of a number of optical design software, optical designers can easily make the optical system to optimize performance, but will also make the complicated optical components, which requires micro-optics manufacturing technology capable of processing optical components of these complex . Of micro-optics designer and manufacturer, the single crystal diamond ultra-precision machining technology has many advantages, for example, can process real three-dimensional structure; forming precision machined parts Dexia micron; the surface roughness of Ra value 5nm, some materials can even reach 1nm; capable of processing large aspect ratio structures. Thus, in the past ten years, ultra-precision processing technology in micro-optics processing application examples are also gradually increased. Such as single crystal diamond ultra-precision machining technology has been successfully applied to contact lenses, prisms, aspheric lenses, microlens arrays, micro-pyramid structure of the surface, antireflection grating structure of the process. Lathe with a single crystal diamond micro-structure. Although the ultra-precision processing technology for optical components processing certain structures have many advantages, but the ultra-precision processing technology combined with replication molding techniques may be the most efficient processing of micro-optics approach, which uses ultra-precision processing technology to process the mold copied and then use the mold to produce micro-optical components. Lathe with a single crystal diamond optical components mold, you need to pay attention to select the appropriate processing parameters to reduce glitches, reduce mold of error, the other to be able to process a suitable diamond tools. Diamond lathe to make the mold for the overhead projector Fresnel lens has been a great success.
