At present, the commonly used optical parts processing technologies mainly include: CNC single-point diamond machining technology, CNC grinding and polishing technology, optical lens molding technology,optical plastic molding technology, magnetorheological polishing technology, electroforming technology and traditional grinding and polishing technology.
1. CNC single-point diamond machining technology
CNC single-point diamond machining technology is a processing technology for aspherical optical parts. It uses a natural single crystal diamond tool on an ultra-precision CNC lathe to process aspherical optical parts by single-point turning of the diamond tool under the precise control conditions of a specific processing environment. This technology is mainly used for optical parts of small and medium size infrared crystals and metal materials.
At present, the materials that can be directly processed to meet the optical surface quality requirements by diamond turning technology are mainly chromatic metals, germanium, plastics and infrared optical crystals. However, the processing of glass cannot meet the requirements of optical surface quality, and it is necessary to continue grinding and polishing correction. Another main use of CNC single-point diamond machining technology is to process various precision molds required for compression molding.
2. CNC grinding and polishing technology
CNC grinding and polishing technology is an optical part manufacturing technology that uses CNC precision machine tools to grind the surface of the workpiece into the required shape, and then polish it with a flexible polishing die to make the workpiece meet the technical requirements. The principle of this technology is closest to the classical optical processing technology, mainly through the digital precision control of the machine tool to achieve the precision processing of optical parts.
The main processing material of CNC grinding and polishing technology is glass, which makes up for the deficiency that CNC single-point diamond processing technology cannot directly process finished optical glass parts. This technology is mainly used to process spherical and aspherical optical parts. It is the main technology to replace the traditional classical method of optical glass processing. It has the advantages of high precision and high processing efficiency.
3. Optical lens molding technology
The optical lens molding technology is to put the softened glass into a high-precision mold, and directly press and mold the optical parts that meet the requirements of use under the conditions of heat, pressure and oxygen. It can be said that the popular application of optical lens molding technology is a major revolution in optical glass parts processing technology. This technology has epoch-making significance for the cost reduction and production increase of aspheric glass parts.
At present, optical lens molding technology has been used to mass-produce precise spherical and aspherical lenses. It can not only manufacture commonly used medium diameter lenses, but also extend to 100 micron microlens arrays and 50 mm larger diameter lenses. It can not only manufacture spherical and aspherical optical parts in military and civilian optical instruments, but also aspherical lenses for optical fiber couplers for optical communication.
