19、越重要的作用，因為這些行業(yè)所需裝備的數(shù)字化已是現(xiàn)代發(fā)展的大趨勢。當前數(shù)控車床呈現(xiàn)以下發(fā)展趨勢。 1.高速、高精密化     高速、精密是機床發(fā)展永恒的目標。隨著科學技術突飛猛進的發(fā)展，機電產(chǎn)品更新?lián)Q代速度加快，對零件加工的精度和表面質(zhì)量的要求也愈來愈高。為滿足這個復雜多變市場的需求，當前機床正向高速切削、干切削和準干切削方向發(fā)展，加工精度也在不斷地提高。另一方面，電主軸和直線電機的成功應用，陶

20、瓷滾珠軸承、高精度大導程空心內(nèi)冷和滾珠螺母強冷的低溫高速滾珠絲杠副及帶滾珠保持器的直線導軌副等機床功能部件的面市，也為機床向高速、精密發(fā)展創(chuàng)造了條件。 數(shù)控車床采用電主軸，取消了皮帶、帶輪和齒輪等環(huán)節(jié)，大大減少了主傳動的轉(zhuǎn)動慣量，提高了主軸動態(tài)響應速度和工作精度，徹底解決了主軸高速運轉(zhuǎn)時皮帶和帶輪等傳動的振動和噪聲問題。采用電主軸結(jié)構(gòu)可使主軸轉(zhuǎn)速達到10000r/min以上。  直線電機驅(qū)動速度高，加減速特性</p>

21、;<p>　　5.智能化、網(wǎng)絡化、柔性化和集成化 　　21世紀的數(shù)控裝備將是具有一定智能化的系統(tǒng)。智能化的內(nèi)容包括在數(shù)控系統(tǒng)中的各個方面：為追求加工效率和加工質(zhì)量方面的智能化，如加工過程的自適應控制，工藝參數(shù)自動生成；為提高驅(qū)動性能及使用連接方面的智能化，如前饋控制、電機參數(shù)的自適應運算、自動識別負載自動選定模型、自整定等；簡化編程、簡化操作方面的智能化，如智能化的自動編程、智能化的人機界面等；還有智能診斷、智能監(jiān)控等方

22、面的內(nèi)容，以方便系統(tǒng)的診斷及維修等。 　　網(wǎng)絡化數(shù)控裝備是近年來機床發(fā)展的一個熱點。數(shù)控裝備的網(wǎng)絡化將極大地滿足生產(chǎn)線、制造系統(tǒng)、制造企業(yè)對信息集成的需求，也是實現(xiàn)新的制造模式，如敏捷制造、虛擬企業(yè)、全球制造的基礎單元。 　　數(shù)控機床向柔性自動化系統(tǒng)發(fā)展的趨勢是：從點(數(shù)控單機、加工中心和數(shù)控復合加工機床)、線(FMC、FMS、FTL、FML)向面(工段車間獨立制造島、FA)、體(CIMS、分布式網(wǎng)絡集成制造系統(tǒng))的方向發(fā)展，另一方
