如(ru)何提(ti)高車床加工精度？

數(shu)控機(ji)床是(shi)集機(ji)械(xie)，液壓，電氣為(wei)一體(ti)的機(ji)床，其中無(wu)論(lun)哪一部分發生故障都(dou)有可能會造成機(ji)床加工精度的降低，廣東普通車床加工，從而使得(de)產品質量(liang)下(xia)降。作為(wei)一個從事數(shu)控加工行業的人，只知道如(ru)何去(qu)用當(dang)然不夠，應該(gai)(gai)了解到(dao)如(ru)何去(qu)維護，更加應該(gai)(gai)知道如(ru)何提高。

造(zao)成機(ji)床加工精度異常(chang)的原(yuan)因(yin)通常(chang)為以下(xia)幾種：①進給單(dan)位被改(gai)動或(huo)變化(hua)；②各個(ge)軸的零(ling)點(dian)偏置異常(chang)；③軸向(xiang)的反向(xiang)間隙異常(chang)；④電機(ji)運行狀態異常(chang)；⑤機(ji)械故障(zhang)，如(ru)絲杠，軸承，軸聯器等部(bu)件。

數(shu)控(kong)車(che)床零件加工有哪些步(bu)驟？

數控車床是數字程序控制車床的簡稱，它集通用性好的型車床、加工精度高的精密型車床和加工的型普通車床的特點于一身，是使用量大、覆蓋面廣的一種機床。自動化數控車床是一種利用數控技術，按照事先編好的程序實現動作的機床。它由程序載體、輸人裝置、CNC單元、伺服系統、位置反饋系統和機床機械部件構成。
