【正文】 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(jí)： 摘 要 隨著社會(huì)不斷進(jìn)步的今天，老式車床已經(jīng)達(dá)不到目前生產(chǎn)生活的目的，普通機(jī)床考齒輪和普通螺絲傳動(dòng)，由于運(yùn)動(dòng)附件存在間隙，加上手工操作的不準(zhǔn)確，因此重復(fù)精度較低，普通機(jī)床測(cè)量時(shí)需停車后手動(dòng)測(cè)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(jī)床投資較低，但對(duì)工人的操作技能要求高。同時(shí)數(shù)控機(jī)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(dòng)條件，利于生產(chǎn)管理的現(xiàn)代化，而且數(shù)控機(jī)床上加工零件，主要取決于加工程序，它與普通機(jī)床不同，不必制造、更換許多工具、夾具、不需要經(jīng)常雕成機(jī)床，所以數(shù)控機(jī)床適用于零件必反更換的場(chǎng)合。因此一些老式的機(jī)床將會(huì)被淘汰，而購(gòu)買一些新的數(shù)控設(shè)備價(jià)格過于昂貴，所以數(shù)控化的推進(jìn)勢(shì)在必行。同時(shí)經(jīng)過大量實(shí)踐證明普通機(jī)床的數(shù)控化改造有一定經(jīng)濟(jì)性，實(shí)用性和穩(wěn)定性。所以很多企業(yè)紛紛將現(xiàn)有機(jī)床改造成經(jīng)濟(jì)型數(shù)控機(jī)床，這種做法具有投資少，見效快的特點(diǎn)，事實(shí)證明：機(jī)床的數(shù)控化 改造可以為企業(yè)帶來可觀的經(jīng)濟(jì)效益。 目前 機(jī)床數(shù)控化在 我國(guó)的普及率不帶 3%，用普通機(jī)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(zhǎng)。從而在國(guó)際、國(guó)內(nèi)市場(chǎng)上缺乏競(jìng)爭(zhēng)力，直接影響一個(gè)企業(yè)的產(chǎn)品、市場(chǎng)、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(jī)床的數(shù)控化率，這里主要介紹數(shù)控機(jī)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。 關(guān)鍵字：機(jī)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, beneficial to the production management modernization, and CNC machine processing parts, depending on the processing procedure, it and mon machine, don39。t manufacture, change different many tools, jigs, and don39。t need often carved into machine, numerical control machine tool used in part so will the change of the occasion. So some oldfashioned machine will be eliminated, and buy some new numerical control equipment price too expensive, so the advancement of numerical control is imperative. Meanwhile, after a lot of practice mon numerical control machine tool that transformation has certain practical economy, and stability. So many businesses will existing machine tools into economical nc machine tools, this kind of practice of less investment, the characteristics of quick results, the fact proved: the numerical control machine tool for enterprise to bring the transformation can be considerable economic benefit. At present numerical control machine tool in our country the prevalence rate of 3%,
