Precision production equipment書坐 used

Traditional machining m睡就ethods (general machining) ar兒湖e the same as precision and ultr大到a precision machining 照子methods. With the adoption分一 of new technology, ne飛南w technology, new equipmen內男t and new testing technology a年離nd instruments, the machining accurac舊微y is constantly improving.

The continuous improv民間ement of machining accuracy reflects得動 the development trend of the l費唱evel of material segmentation from t湖開he macro into the micro wor著南ld. As time goes on, the machining農他 accuracy which is considered dif喝知ficult to achieve wil師但l become relatively eas計議y. Therefore, ordinary processing, prec東這ision machining and ultra preci笑女sion machining are only a relative co房上ncept, and the boundaries be我醫tween them vary with time. Th舞水e typical example of pr白關ecision cutting and ultra precisio有頻n machining is diamo紅影nd cutting.

Diamond cutting is taken as an example門畫. The radius of the knife edge has been業關 developing in a smaller directi小湖on. Because its size directly a場道ffects the roughness of t妹學he machined surface, it is di西雨rectly related to the refl現行ectivity of the optical木紅 mirror, and the requirement for the 少一reflectivity of the equipment離火 is getting higher and higher. If the 一城reflectivity of the laser gyroscope ref我吃lector has been raised 對我to 99.99%, this will inevitably r科船equire diamond tools to be sharper.金什 In order to carry out the紅舞 thinning test, the target is 科鄉to achieve chip thickness of nm, and t區但he radius of the tool edge s喝子hould approach 2.4nm. In order to achie員國ve this height, the diamond grin業開der has changed the 金飛traditional structure. The spindle bear外土ing adopts the air beari說山ng as the support, the end face of th劇藍e grinding disc can be c區懂orrected by the machine it了匠self, so that the end face of the gri場不nding disc is controlled by 0坐化.5μ m below.

In terms of cutting tools, diam明村ond grinding wheel is u和南sed to control the a內他mount of feed and feed on the back愛亮. In ultra precision grindi女不ng machine, ductile grindi體飛ng can be carried out哥她, namely nano grinding.睡訊 Optical surfaces can be obtaine民又d even on the surface of glass. 2 笑匠the development trend of preci靜又sion processing and ultra precision pr火購ocessing is from the viewp醫姐oint of long-term developme樂音nt. Manufacturing technology is the ma家東in direction and strategic decision西相 of developing national economy in all近件 countries. It is one of the impo窗村rtant means of national economic d日新evelopment. At the same time, it is路物 a country's independen他聽t, prosperous and sustained econ校事omic development. A long - te票國rm plan to keep the lea爸訊d in technology. The de化相velopment of science an務近d technology has also put 都通forward higher requirements for preci高綠sion machining and ultra precision mach地花ining technology. From 謝鐵large to celestial telescope le林了ns, small to large scale int白聽egrated circuit line width μ m requi鐵腦rements for micro and micromec數個hanical micro and nano size 好街parts, regardless of size, the木現 maximum size accuracy is close to路學 nanometer; the shape of parts女話 is increasingly complex, various asphe男民ric is the current very typical ge金算ometric shape. Micromechanical t通文echnology brings a new trend 藍器for ultra precision manufacturi喝很ng technology. Its micro degree makes 術場the traditional manufac服秒turing technology face a new 拍知challenge, promotes the improvement o拿少f the technical performance of年就 various products.

With the pursuit of high q高鄉uality, miniaturization,什街 high reliability and h農志igh performance, the ultra pr都厭ecision machining technology has been 一飛developed rapidly, and it has be事綠come an important part of 火土modern manufacturing ind要務ustry.
