Parti di fresatura CNC ad altissima precisione

In the early 1960s, due to the gyroscopes used in aerospace, the drums and disks used in computers, and the polygonal prism parts used in optical scanning. Large-diameter non-circular curved mirror parts for high-power laser nuclear fusion devices, as well as stereoscopic mirrors for various complex shapes of infrared light, eccetera. All kinds of mirrors and multi-faceted prism parts require extremely high precision, and they are processed by grinding, macinazione, polishing and other methods. Not only the processing cost is high, but it is also difficult to meet the requirements of accuracy and surface roughness. A tal fine, the research and development of the use of high-precision, high-rigidity machine tools and diamond tools for cutting and milling processing methods.

Il taglio ultrapreciso è iniziato con la tecnologia SPDT, che è supportato da mandrini con cuscinetti ad aria, slitte pneumatiche, elevata rigidità, strumenti di alta precisione, controllo del feedback, e controllo della temperatura ambientale per ottenere rugosità superficiale a livello nanometrico. Vengono utilizzate soprattutto le frese diamantate, che trovano largo impiego nella lavorazione di elementi ottici piatti e asferici in rame, plexiglas, prodotti in plastica (come le lenti in plastica della fotocamera, lenti per lenti a contatto, eccetera.), ceramiche e materiali compositi.

Ultra-precision cutting and milling technology is an advanced manufacturing technology developed to meet the needs of modern high-tech. Precision CNC machining is an indispensable key technology in the development of high-tech cutting-edge products, an important symbol of a country’s manufacturing level, and one of the indispensable key technologies for equipment modernization. Precision parts have very broad application prospects in military and civilian industries.
