摘要
經(jīng)調(diào)研發(fā)現(xiàn)，我國(guó)大多數(shù)企業(yè)擁有數(shù)量眾多和較長(zhǎng)使用壽命的普通機(jī)床，其加工精度較低，不能批量生產(chǎn)，自動(dòng)化程度不高，適應(yīng)性差，但考慮投資成本，產(chǎn)業(yè)的連續(xù)性，又不能馬上被淘汰。
購(gòu)買新的數(shù)控機(jī)床是提高產(chǎn)品質(zhì)量效率的重要途徑，但成本高，許多企業(yè)在短期內(nèi)無法實(shí)現(xiàn)，這嚴(yán)重阻礙企業(yè)設(shè)備更新的步伐。為此把普通車床數(shù)控化改造，不失為一條投資少，提高產(chǎn)品質(zhì)量和生產(chǎn)效率的的捷徑，提升企業(yè)競(jìng)爭(zhēng)力，在我國(guó)成為制造強(qiáng)國(guó)的進(jìn)程中占有一席之地。
本文以普通車床CA6132數(shù)控化改造為例，從普通車床改造的經(jīng)濟(jì)性評(píng)價(jià)入手，對(duì)數(shù)控技術(shù)在普通車床CA6132數(shù)控化改造應(yīng)用作了深入研究和探索，形成相應(yīng)的技術(shù)方案及要點(diǎn)。主要內(nèi)容：
對(duì)普通車床數(shù)控化改造經(jīng)濟(jì)性評(píng)價(jià)詳細(xì)論證，確定普通車床數(shù)控化改造方案；對(duì)進(jìn)給系統(tǒng)的滾珠絲杠型號(hào)選擇與裝配設(shè)計(jì)，支承方式的設(shè)計(jì)與軸承型號(hào)的選擇，步進(jìn)電機(jī)的選擇等進(jìn)行詳細(xì)研究; 對(duì)常用進(jìn)口數(shù)控裝置系統(tǒng)和國(guó)產(chǎn)數(shù)控裝置系統(tǒng)進(jìn)行仔細(xì)比較，根據(jù)所改造的性能和精度指標(biāo)來選擇數(shù)控裝置系統(tǒng)和自動(dòng)刀架型號(hào)； 給出普通車床數(shù)控化改造的安裝及調(diào)試方法。

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
