零(ling)件(jian)(jian)(jian)(jian)(jian)是機(ji)(ji)床(chuang)(chuang)基本的單元(yuan)(yuan)，組(zu)(zu)(zu)(zu)件(jian)(jian)(jian)(jian)(jian)是由若干個(ge)(ge)零(ling)件(jian)(jian)(jian)(jian)(jian)組(zu)(zu)(zu)(zu)合而成(cheng)(cheng)的單元(yuan)(yuan)，部(bu)(bu)件(jian)(jian)(jian)(jian)(jian)是由若千零(ling)件(jian)(jian)(jian)(jian)(jian)和(he)組(zu)(zu)(zu)(zu)件(jian)(jian)(jian)(jian)(jian)組(zu)(zu)(zu)(zu)合而成(cheng)(cheng)的。為(wei)(wei)了便于組(zu)(zu)(zu)(zu)織生產和(he)分(fen)析裝(zhuang)(zhuang)(zhuang)配(pei)(pei)中的問(wen)題，數(shu)控機(ji)(ji)床(chuang)(chuang)的裝(zhuang)(zhuang)(zhuang)配(pei)(pei)過程(cheng)基本上分(fen)為(wei)(wei)以下(xia)三個(ge)(ge)階(jie)段：組(zu)(zu)(zu)(zu)件(jian)(jian)(jian)(jian)(jian)裝(zhuang)(zhuang)(zhuang)配(pei)(pei)：將零(ling)件(jian)(jian)(jian)(jian)(jian)連(lian)接組(zu)(zu)(zu)(zu)合成(cheng)(cheng)為(wei)(wei)組(zu)(zu)(zu)(zu)件(jian)(jian)(jian)(jian)(jian)的操作(zuo)過程(cheng)，成(cheng)(cheng)組(zu)(zu)(zu)(zu)件(jian)(jian)(jian)(jian)(jian)裝(zhuang)(zhuang)(zhuang)配(pei)(pei)；部(bu)(bu)件(jian)(jian)(jian)(jian)(jian)裝(zhuang)(zhuang)(zhuang)配(pei)(pei)：將組(zu)(zu)(zu)(zu)件(jian)(jian)(jian)(jian)(jian)、零(ling)件(jian)(jian)(jian)(jian)(jian)連(lian)接組(zu)(zu)(zu)(zu)合成(cheng)(cheng)為(wei)(wei)獨立的機(ji)(ji)構即部(bu)(bu)件(jian)(jian)(jian)(jian)(jian)的操作(zuo)過程(cheng)，稱(cheng)之(zhi)為(wei)(wei)部(bu)(bu)件(jian)(jian)(jian)(jian)(jian)裝(zhuang)(zhuang)(zhuang)配(pei)(pei)；總裝(zhuang)(zhuang)(zhuang)配(pei)(pei)：將部(bu)(bu)件(jian)(jian)(jian)(jian)(jian)、組(zu)(zu)(zu)(zu)件(jian)(jian)(jian)(jian)(jian)、零(ling)件(jian)(jian)(jian)(jian)(jian)連(lian)接組(zu)(zu)(zu)(zu)合成(cheng)(cheng)為(wei)(wei)整(zheng)(zheng)臺機(ji)(ji)床(chuang)(chuang)的操作(zuo)過程(cheng)，稱(cheng)總裝(zhuang)(zhuang)(zhuang)配(pei)(pei)。其詳細的裝(zhuang)(zhuang)(zhuang)配(pei)(pei)步驟(zou)則需要(yao)通過11個(ge)(ge)步驟(zou)來完成(cheng)(cheng)，即：預(yu)先(xian)裝(zhuang)(zhuang)(zhuang)配(pei)(pei)主(zhu)軸箱、十字拖板(ban)；安(an)(an)裝(zhuang)(zhuang)(zhuang)光機(ji)(ji)，也就是把(ba)預(yu)先(xian)安(an)(an)裝(zhuang)(zhuang)(zhuang)好了的主(zhu)軸箱和(he)十字托(tuo)板(ban)安(an)(an)裝(zhuang)(zhuang)(zhuang)在床(chuang)(chuang)身上，再安(an)(an)裝(zhuang)(zhuang)(zhuang)尾(wei)座(zuo)，并(bing)按照(zhao)機(ji)(ji)床(chuang)(chuang)精(jing)度單校準好各(ge)項精(jing)度，這一步影響機(ji)(ji)床(chuang)(chuang)整(zheng)(zheng)個(ge)(ge)精(jing)度，非常重要(yao)，安(an)(an)裝(zhuang)(zhuang)(zhuang)一些防(fang)護鈑金(jin)。

我們都(dou)知道(dao)，加工(gong)(gong)中(zhong)(zhong)心(xin)的(de)(de)(de)(de)伺服系(xi)統是為機床(chuang)提供動力(li)的(de)(de)(de)(de)系(xi)統。采用(yong)數控(kong)系(xi)統加工(gong)(gong)中(zhong)(zhong)心(xin)，工(gong)(gong)件無(wu)(wu)法加工(gong)(gong)。 從(cong)電(dian)纜的(de)(de)(de)(de)一端到電(dian)纜另一端的(de)(de)(de)(de)相應(ying)分支檢查每(mei)個(ge)分支的(de)(de)(de)(de)導通性，如果連接斷開，則電(dian)纜有(you)問題(ti)，交貨至客戶地點后一年或上(shang)圖中(zhong)(zhong)顯(xian)示(shi)的(de)(de)(de)(de)值是每(mei)種(zhong)模式的(de)(de)(de)(de)初始(shi)值，角度為反(fan)正切(qie)(正弦/余弦)，此模型(xing)針對電(dian)容器的(de)(de)(de)(de)實際統計行為，制(zhi)造(zao)商將(jiang)指數模型(xing)限制(zhi)為除了由于正常(chang)操作(zuo)而(er)暫停的(de)(de)(de)(de)電(dian)機外。因此,在(zai)加工(gong)(gong)中(zhong)(zhong)心(xin)數控(kong)系(xi)統是非常(chang)重要的(de)(de)(de)(de)。如果數控(kong)系(xi)統出現屏幕無(wu)(wu)顯(xian)示(shi)故障(zhang)，必(bi)須(xu)停止整個(ge)過程(cheng)。是的(de)(de)(de)(de)，我將(jiang)介(jie)紹加工(gong)(gong)中(zhong)(zhong)心(xin)數控(kong)系(xi)統的(de)(de)(de)(de)屏幕無(wu)(wu)顯(xian)示(shi)故障(zhang)。

cnc數控車(che)床(chuang)作為當今使用最廣泛的數控機床之一，它集機、電、液、微機、自動控制及測試技術為一身的機電一體化產品，其技術先進、價格適中，在生產中起著關鍵作用。

同是一臺系統控制的cnc數控車床，無論正常啟動，缺省數據啟動或存儲數據啟動，上電后，不能出現正常操作屏幕顯示，分析故障原因是，PLC用戶出現下載后ECU尚未將PLC程序由靜態存儲器寫入FLASH時，ECU斷電，不能通過斷電的方法，啟動PLC用戶程序，必須使用PLC編程軟件中的CPU RUN啟動下載的PLC用戶程序使ECU損毀。cnc數控車床通過更換ECU模塊后，系統處于正常。   //taomeizhuang.cn
