北京机械加工厂认为(wei)传统(tong)的(de)机(ji)械加工(gong)(gong)都是用手(shou)工(gong)(gong)操作(zuo)普通(tong)机(ji)床(chuang)作(zuo)业的(de)，加工(gong)(gong)时用手(shou)摇动(dong)(dong)机(ji)械刀具(ju)切(qie)削金(jin)属，靠眼(yan)睛用卡尺等工(gong)(gong)具(ju)测量产品的(de)精度的(de)。然而现代工(gong)(gong)业早已使用电脑数字(zi)化控制的(de)机(ji)床(chuang)进行作(zuo)业，数控机(ji)床(chuang)可(ke)以按照技术人员(yuan)事先编好的(de)程(cheng)序(xu)自(zi)动(dong)(dong)对任何产品和零部件直接进行加工(gong)(gong)。
现代数控机床(chuang)的(de)(de)发展方向是(shi)高速化、高精度(du)化、高可靠性、多功(gong)能(neng)、复合化、智(zhi)(zhi)能(neng)化和开(kai)(kai)放式结构。主(zhu)要(yao)发展趋势是(shi)研(yan)制(zhi)开(kai)(kai)发软、硬件都具有(you)开(kai)(kai)放式结构的(de)(de)智(zhi)(zhi)能(neng)化全功(gong)能(neng)通用数控装(zhuang)置(zhi)。数控技(ji)(ji)(ji)术(shu)是(shi)机械(xie)加工自动(dong)化的(de)(de)基础(chu)，是(shi)数控机床(chuang)的(de)(de)核心技(ji)(ji)(ji)术(shu)，其水平(ping)(ping)高低关系到国家(jia)战略地(di)位和体现国家(jia)综(zong)合实(shi)力(li)的(de)(de)水平(ping)(ping). 它随着信息技(ji)(ji)(ji)术(shu)、微电子(zi)技(ji)(ji)(ji)术(shu)、自动(dong)化技(ji)(ji)(ji)术(shu)和检测技(ji)(ji)(ji)术(shu)的(de)(de)发展而(er)发展。
CNC(数控(kong)机(ji)床(chuang))是计算机(ji)数字控(kong)制机(ji)床(chuang)(Computer numerical control)的(de)(de)简称，是一种由程序控(kong)制的(de)(de)自(zi)动(dong)(dong)化机(ji)床(chuang)。该控(kong)制系统能(neng)够逻辑地处(chu)理具(ju)有(you)控(kong)制编码(ma)或其他符(fu)号(hao)指(zhi)令规(gui)定的(de)(de)程序，通过(guo)计算机(ji)将(jiang)其译码(ma)，从而使机(ji)床(chuang)执行规(gui)定好了的(de)(de)动(dong)(dong)作，通过(guo)刀具(ju)切削(xue)将(jiang)毛坯料加工成(cheng)半(ban)成(cheng)品成(cheng)品零(ling)件。
CNC加(jia)工(gong)(gong)(gong)(gong)零(ling)件(jian)的(de)特点是：被加(jia)工(gong)(gong)(gong)(gong)零(ling)件(jian)经过一次装夹后，数控系(xi)统能控制机床按(an)不同的(de)工(gong)(gong)(gong)(gong)序(xu)自(zi)动(dong)(dong)选择(ze)和更换刀具(ju)；自(zi)动(dong)(dong)改变机床主(zhu)轴(zhou)转(zhuan)速、进给(ji)量(liang)和刀具(ju)相对工(gong)(gong)(gong)(gong)件(jian)的(de)运动(dong)(dong)轨迹(ji)及其它辅(fu)助功能，连续地(di)对工(gong)(gong)(gong)(gong)件(jian)各加(jia)工(gong)(gong)(gong)(gong)面自(zi)动(dong)(dong)地(di)进行钻孔(kong)(kong)、锪(huo)孔(kong)(kong)、铰孔(kong)(kong)、镗孔(kong)(kong)、攻螺纹(wen)、铣削等多(duo)工(gong)(gong)(gong)(gong)序(xu)加(jia)工(gong)(gong)(gong)(gong)。由于加(jia)工(gong)(gong)(gong)(gong)中(zhong)心能集中(zhong)地(di)、自(zi)动(dong)(dong)地(di)完成多(duo)种工(gong)(gong)(gong)(gong)序(xu)，避免(mian)了(le)人为的(de)操作误(wu)差(cha)、减少了(le)工(gong)(gong)(gong)(gong)件(jian)装夹、测(ce)量(liang)和机床的(de)调整时间(jian)(jian)及工(gong)(gong)(gong)(gong)件(jian)周转(zhuan)、搬(ban)运和存放时间(jian)(jian)，大大提高了(le)加(jia)工(gong)(gong)(gong)(gong)效率(lv)和加(jia)工(gong)(gong)(gong)(gong)精(jing)度(du)，所(suo)以具(ju)有良(liang)好(hao)的(de)经济效益。加(jia)工(gong)(gong)(gong)(gong)中(zhong)心按(an)主(zhu)轴(zhou)在空(kong)间(jian)(jian)的(de)位(wei)置(zhi)可分(fen)为立式(shi)(shi)加(jia)工(gong)(gong)(gong)(gong)中(zhong)心与卧(wo)式(shi)(shi)加(jia)工(gong)(gong)(gong)(gong)中(zhong)心。
