Precision machining technology木答 has developed rapidly舊金 in terms of improving accuracy an能木d productivity. In terms of i讀近ncreasing productivity, increasing the商鐵 degree of automation is the dir少為ection that countries可視 are committed to developme我銀nt. Precision parts processing has d不外eveloped rapidly from 通說CNC to CIMS in recent years,海空 and has been applied within a cert化媽ain range. From improv微知ing precision, from precision machining河文 to ultra-precision machi都舞ning, this is also the direction of de那下velopment of major develope章暗d countries in the world花都.
(1) Technical a文歌nd technological advantage家身s of precision machining
Com新照pared with the roomle制要ss process, the advantages of pre好拿cision machining and c線雨utting work are firstly that it has a雨有 high material removal rate的大 and good economy. For exampl知化e, compared with laser p水些lasma processing tec國些hnology, this is because of thi聽說s. At present, only a large supply of 什來this technology can ac照站hieve a high material removal rate.要店 On the other hand, there 媽近are still questions about wheth弟子er the processed workpiece can m筆能eet the requirements懂大 of size and shape accuracy.鄉水 Chipless pressure machining is mainly白動 used for mass production, and often 著通requires subsequent cutting to obtain t友年he final qualified shap新對e of the workpiece. Therefore購中, the main advantage可黑 of machining is to 音民enable the workpiece 靜農to achieve higher accur去歌acy. Precision machining is widely美請 used, especially with the d美學evelopment trend of small些雜 batch production, the s答員hape and dimensional accuracy o少錢f workpieces are becomi商火ng higher and higher, w音小hich has opened up a new and坐我 more extensive field f師雜or precision machining. The use of l都書athes naturally requires va化舊rious turning processes, but 舞離it should also be no關金ted that the machining processes 習冷such as drilling, milling, grinding, an飛話d gear cutting can all be done o年和n one lathe (process 得我integration). This is the trend now北體 developed. The machining metho通妹d of the compound machi物雪ne tool of the turnin拍書g and milling machining center. Do兒校ngguan precision machining
(2) Precision machini業動ng methods
According to志門 the mechanism and characteristics of科南 the machining method, 媽媽precision machining can be divided int術喝o four categories: tool cutting, abrasi員開ve machining, special machining an書但d compound machining.
