out of the machine tool product exists generally poor quality, variety, less, the high cost and low class long delivery. Thus in the international and domestic market petitiveness, the lack of a direct influence on the product of the enterprise, market, benefits, affect the enterprise survival and development, so must increase the strength of the machine tool improve numerical control rate, here basically introduces the numerical control machine tool spindle transformation, including the transformation of the structure, performance choice for future more deepening of exploration and research. Key word: machine, numerical control, the transformation, the meaning 目錄 一、 數(shù)控化改造的必要性 當(dāng)代人類社會快速發(fā)展,正在進行第三次工業(yè)革命,由于社會生產(chǎn)力的快速發(fā)展,工業(yè)發(fā)達國家的軍、民機械工業(yè),在上世紀 70 年代末、 80 年代初已經(jīng)開始大規(guī)模應(yīng)用數(shù)控機床,其本質(zhì)是,采用信息技術(shù)對傳統(tǒng)產(chǎn)業(yè)(包括軍、民機械工業(yè))進行技術(shù)改造。t manufacture, change different many tools, jigs, and don39。從而在國際、國內(nèi)市場上缺乏競爭力,直接影響一個企業(yè)的產(chǎn)品、市場、效益、影響企業(yè)的生存和發(fā)展,所以必須加大力量提高機床的數(shù)控化率,這里主要介紹數(shù)控機床主軸改造,包括結(jié)構(gòu)的改造,性能的選擇以備將來更深化的探索和研究。所以很多企業(yè)紛紛將現(xiàn)有機床改造成經(jīng)濟型數(shù)控機床,這種做法具有投資少,見效快的特點,事實證明:機床的數(shù)控化 改造可以為企業(yè)帶來可觀的經(jīng)濟效益。因此一些老式的機床將會被淘汰,而購買一些新的數(shù)控設(shè)備價格過于昂貴,所以數(shù)控化的推進勢在必行。 CA6140 車床主軸加工工藝數(shù)控化改造 作者姓名: 指導(dǎo)教師: 學(xué)科專業(yè): 班 級: 摘 要 隨著社會不斷進步的今天,老式車床已經(jīng)達不到目前生產(chǎn)生活的目的,普通機床考齒輪和普通螺絲傳動,由于運動附件存在間隙,加上手工操作的不準確,因此重復(fù)精度較低,普通機床測量時需停車后手動測量,誤差 較大,效率低下,比較適合批量較小,精度要求不高,零活類零件,雖然老式機床投資較低,但對工人的操作技能要求高。同時數(shù)控機床具有高度柔性,加工精度高,加工質(zhì)量穩(wěn)定 、可靠,生產(chǎn)率高,改善勞動條件,利于生產(chǎn)管理的現(xiàn)代化,而且數(shù)控機床上加工零件,主要取決于加工程序,它與普通機床不同,不必制造、更換許多工具、夾具、不需要經(jīng)常雕成機床,所以數(shù)控機床適用于零件必反更換的場合。同時經(jīng)過大量實踐證明普通機床的數(shù)控化改造有一定經(jīng)濟性,實用性和穩(wěn)定性。 目前 機床數(shù)控化在 我國的普及率不帶 3%,用普通機床加工出來的產(chǎn)品普遍存在質(zhì)量差、品種少、檔次低、成本高、供貨期長。 關(guān)鍵字:機床、數(shù)控化、改造、意義 CA6140 lathe spindle numerical control processing technology transformation Along with the social progress today, old lathe have not reach the current production the purpose of life, mon and ordinary screw machine test gear transmission, due to a sports accessories, and existing gap manual inaccurate repeat, so low precision machine tools, ordinary when measuring the need to manually measurement error after parking, bigger, the efficiency is low, the more suitable for small batch, precision demand is not high, a job parts, although the old machine tool investment, but for low labor practices demand is high. At the same time numerical control machine with high flexibility, high machining accuracy, processing quality is stable, reliable and high productivity, improve working conditions
