摘要
　　  當今世界數(shù)控技術及裝備發(fā)展的趨勢及我國數(shù)控裝備技術發(fā)展和產(chǎn)業(yè)化的現(xiàn)狀，在此基礎上討論了在我國加入WTO和對外開放進一步深化的新環(huán)境下，發(fā)展我國數(shù)控技術及裝備、提高我國制造業(yè)信息化水平和國際競爭能力的重要性，并從戰(zhàn)略和策略兩個層面提出了發(fā)展我國數(shù)控技術及裝備的幾點看法。     裝備工業(yè)的技術水平和現(xiàn)代化程度決定著整個國民經(jīng)濟的水平和現(xiàn)代化程度，數(shù)控技術及裝備是發(fā)展新興高新技術產(chǎn)業(yè)和尖端工業(yè)（如信息技術及其產(chǎn)業(yè)、生物技術及其產(chǎn)業(yè)、航空、航天等國防工業(yè)產(chǎn)業(yè)）的使能技術和最基本的裝備。馬克思曾經(jīng)說過“各種經(jīng)濟時代的區(qū)別，不在于生產(chǎn)什么，而在于怎樣生產(chǎn)，用什么勞動資料生產(chǎn)”。制造技術和裝備就是人類生產(chǎn)活動的最基本的生產(chǎn)資料，而數(shù)控技術又是當今先進制造技術和裝備最核心的技術。當今世界各國制造業(yè)廣泛采用數(shù)控技術，以提高制造能力和水平，提高對動態(tài)多變市場的適應能力和競爭能力。此外世界上各工業(yè)發(fā)達國家還將數(shù)控技術及數(shù)控裝備列為國家的戰(zhàn)略物資，不僅采取重大措施來發(fā)展自己的數(shù)控技術及其產(chǎn)業(yè)，而且在“高精尖”數(shù)控關鍵技術和裝備方面對我國實行封鎖和限制政策?？傊?，大力發(fā)展以數(shù)控技術為核心的先進制造技術已成為世界各發(fā)達國家加速經(jīng)濟發(fā)展、提高綜合國力和國家地位的重要途徑。     數(shù)控技術是用數(shù)字信息對機械運動和工作過程進行控制的技術，數(shù)控裝備是以數(shù)控技術為代表的新技術對傳統(tǒng)制造產(chǎn)業(yè)和新興制造業(yè)的滲透形成的機電一體化產(chǎn)品，即所謂的數(shù)字化裝備，其技術范圍覆蓋很多領域：(1)機械制造技術；(2)信息處理、加工、傳輸技術；(3)自動控制技術；(4)伺服驅(qū)動技術；(5)傳感器技術；(6)軟件技術等。

      The transformation and design of the economic CNC lathe                                                                                                                                                                                    ABSTRACT
　　　The survey found that most enterprises of china still have large amounts general-purpose machine tools which have longevity of service, low precision, can not adapt to mass production , low automatization and adaptability ,but can not be washed out because of its low cost and continuity of enterprise's production
　　　Purchasing new numerically controlled machines is an important way to improve production precision and efficiency, but it may not come true to many enterprises because it cost much. Enterprise's equipment updating step are counteracted severly. So General lathe's numerically controlled reforming is a quick way that costs less, improve production precision and efficiency, and it can improve enterprises' competitive power. So it can takes its place in our way to a powerful manufacturing country.           
　　　The economical efficiency of the reform and the application of NC technology in General purpose lathe CA6132's numerically controlled reforming is researched in this paper according to our practice of CA6132's numerically controlled reforming. And the reforming scheme and main points are formed. The main contents is: 
　　　    The economical efficiency of the reform is eva luated in detail and the rerorming scheme is maked according to misty optimum's synthesize adjudicate principle.The ball screw's type, assembling, supporting, bearing type, and stepping motor of feeding system is designed.he import and domestic NC systems were compared carefully, brought up a choose method and selected the NC system and automatic tool rest according to the function. Methods of installing and testing of general purpose lathe's numerically controlled reforming were put forward.                                                                   KEY WORDS: General purpose lathe; NC reform ; Servo system ; CNC system
