Precision production那黑 equipment used

Traditional machining me生習thods (general machining) are的話 the same as precisio子黑n and ultra precision 海嗎machining methods. With th會舞e adoption of new te數站chnology, new technolo動器gy, new equipment and new 現音testing technology a商個nd instruments, the machi司少ning accuracy is constantly 如鐵improving.

The continuous improvement of machini花舊ng accuracy reflects 見工the development trend of the 白光level of material segmentation f子公rom the macro into th生科e micro world. As time goes on, the mac國北hining accuracy which is considered dif家相ficult to achieve will b煙雨ecome relatively easy. There男村fore, ordinary processing, precision畫是 machining and ultra precision ma是我chining are only a rel對門ative concept, and the boun問日daries between them vary w商女ith time. The typical example o樂有f precision cutting and 體熱ultra precision machining is dia水開mond cutting.

Diamond cutting is taken as 空報an example. The radius of the kn亮媽ife edge has been developing in 信東a smaller direction. Because its外熱 size directly affects the roughness o間美f the machined surface, it is directly 慢員related to the reflectivity of t明理he optical mirror, and the requi鐵好rement for the reflectivity of th理爸e equipment is getting 笑明higher and higher. If th少紅e reflectivity of the las城舊er gyroscope reflector 校不has been raised to 99.99%, this will快西 inevitably require diamond t關新ools to be sharper. In街錢 order to carry out the thinning t術的est, the target is to achieve 湖影chip thickness of nm, and the radius 光睡of the tool edge should 北爸approach 2.4nm. In order to ach你吧ieve this height, the diamo熱道nd grinder has changed the tradit件河ional structure. The spindle bearing 風術adopts the air bearing購但 as the support, the end f訊們ace of the grinding disc can be美答 corrected by the machine itsel年動f, so that the end face of the g件件rinding disc is controlled by 0.森信5μ m below.

In terms of cutting tools, diamond gri下筆nding wheel is used to co一舞ntrol the amount of fe視跳ed and feed on the back. In 暗會ultra precision grinding machine, du嗎嗎ctile grinding can be carrie唱現d out, namely nano grinding. O來風ptical surfaces can be obtained e朋雜ven on the surface of glass. 2 the deve坐醫lopment trend of precision process海習ing and ultra precisi微亮on processing is from the viewp低銀oint of long-term devel男關opment. Manufacturing 資學technology is the main di雜錯rection and strategic decision of dev就司eloping national econ文花omy in all countries. It is低裡 one of the important means of玩購 national economic development. At th鐵醫e same time, it is a c人來ountry's independ事很ent, prosperous and su文件stained economic development我農. A long - term plan to keep 區離the lead in technology. The deve少師lopment of science and 醫生technology has also put forward high就那er requirements for precision 黃商machining and ultra precision machining照快 technology. From large to 外小celestial telescope lens, small 暗可to large scale integrated circu線紅it line width μ m requi很身rements for micro and micromechan間作ical micro and nano size 城拍parts, regardless of size, the maximum 的地size accuracy is close to na紅煙nometer; the shape of parts is incr鐵工easingly complex, vari輛街ous aspheric is the curren也校t very typical geomet長北ric shape. Micromechanica飛錢l technology brings a new trend for ult章行ra precision manufacturing techn報日ology. Its micro degree makes the tradi雪不tional manufacturing technolo我光gy face a new challenge, promotes the 暗新improvement of the technical perfo唱路rmance of various pr低話oducts. The development process pres農姐ents a spiral circula都冷r development, and cont老快ributes directly to 做銀the progress of scie鐘費nce and technology and human civil光喝ization. With the pursuit of high q關音uality, miniaturization, high reliab開他ility and high performance, the ultra森厭 precision machining術銀 technology has been develop線車ed rapidly, and it has become an i議空mportant part of modern manufa裡議cturing industry.
