【正文】 curacy and the high efficiency, and obtains the good benefit, the key is decided by its reliable height. 3. function rebine function rebine goal is further enhances the engine bed the production efficiency, uses reduces to few in the nonprocessing noncutting the function rebine, may expand the engine bed the use scope, enhances the efficiency, realizes multipurpose one machine, one machine many energy, namely a numerical control lathe already may realize the turning function, also may realize the milling processing。 Also has the intelligence to diagnose, aspect and so on intelligent monitoring contents, by facilitates the system the diagnosis and the service and so on. The numerical control engine bed the tendency which develops to the flexibility automated system is: From (numerical control single plane, processing center and numerical control pound processing engine bed), line (FMC, FMS, FTL, FML) to surface (construction section workshop independent manufacture island, FA), body (CIMS, distribution work integration manufacture system) the direction develops, on the other hand develops to the attention utility and the efficient direction. The flexible automation technology is the manufacturing industry adapts the dynamic market demand and the product rapid renewal main method, is the various countries39。隨著科學(xué)技術(shù)突飛猛進(jìn)的發(fā)展，機(jī)電產(chǎn)品更新?lián)Q代速度加快，對(duì)零件加工的精度和表面質(zhì)量的要求也愈來(lái)愈高。采用電主軸結(jié)構(gòu)可使主軸轉(zhuǎn)速達(dá)到 10000r/min 以上。 通過(guò)直線電機(jī)和直線滾動(dòng)導(dǎo)軌副的應(yīng)用，可使機(jī)床的快速移動(dòng)速度由目前的 10～20m/mim 提高到 60～ 80m/min，甚至高達(dá) 120m/min。 CAD不僅可以替代人工完成繁瑣的繪圖工作，更重要的是可以進(jìn)行設(shè)計(jì)方案選 擇和大件整機(jī)的靜、動(dòng)態(tài)特性分析、計(jì)算、預(yù)測(cè)及優(yōu)化設(shè)計(jì)，可以對(duì)整機(jī)各工作部件進(jìn)行動(dòng)態(tài)模擬仿真。 功能復(fù)合化的目的是進(jìn)一步提高機(jī)床的生產(chǎn)效率，使用于非加工輔助時(shí)間減至最少。該機(jī)床還配置有強(qiáng)動(dòng)力刀架和副主軸。 網(wǎng)絡(luò)化數(shù)控裝備是近年來(lái)機(jī)床發(fā)展的一個(gè)熱點(diǎn)。其重點(diǎn)是以提高系統(tǒng)的可靠性、實(shí)用化為前提，以易于聯(lián)網(wǎng)和集成為目標(biāo)，注重加強(qiáng)單元技術(shù)的開拓和完善。
