Stress Disk Polishing (SLP) is a computer-controlled polishing technology. It is based on the basic application of the mathematical mechanics of shell elastic deformation. Using a large size abrasive stress disc with controllable elastic deformation, active deformation technology is used. for polishing. This polishing method is mainly used in the fields of optical engineering and materials and devices, including optical design and processing, optical polishing, etc. The strain disk polisher is a scientific instrument specially used for this technology, which plays an important role in the engineering and technology fields related to information and systems science. This polishing technology has a place in the polishing of ultra-precision optical components due to its precision and controllability. It is closely related to small grinding head polishing (CCOS), liquid jet polishing (FJP), ion beam polishing (IBF) and air polishing. Bonnet polishing and magnetorheological polishing (MRF) together constitute the CNC polishing method currently widely used in the polishing of ultra-precision optical components
1. Principle
Stress disk polishing technology is a surface treatment method that uses abrasives composed of chemical liquids and hard particles to treat the surface under the action of high-speed rotation of the stress disk. During the machining process, due to the high-speed rotation of the stress plate, friction will occur between the grinding material and the surface, causing defects and irregularities on the surface to be rejected or filled. At the same time, the presence of chemical liquid can also remove impurities such as oxides and metal ions on the surface, thereby making the surface smoother and finer.
2. Features
(1) Effectiveness
Strain disc polishing technology can effectively process the surface in a short time and process the surface of different materials. In addition to being used for metallic materials, this technology can also be used for processing non-metallic materials such as semiconductors, glass and quartz.
(2) High precision
Strain disc polishing technology can effectively improve surface roughness and finish, and can achieve large-area flatness at the submicron level.
(3) Environmental protection
Compared with traditional mechanical processing and electrochemical grinding technologies, strain disc polishing technology produces relatively less liquid waste, and the discharged waste liquid is more environmentally friendly after pretreatment, in line with national environmental protection requirements. the environment.
3. Request
