西門子數控機床231131/F31125故障修理檢測，西門子伺服電機維修，西門子數控系統維修，使用前都應該測量數控機床繞組和繞組對地絕緣電阻。對繞線式轉子電動機，除榆查定子絕緣外，同時還應檢查轉子繞組及滑環對地和滑環之間的絕緣電阻，一般三相380V電動機的絕緣電阻應大于0.5MΩ，這個才是比較正常的。
② 一定要看數控機床銘牌上面所表示電壓、頻率、接法與電路電壓等是否相符，接法是否正確。
③ 檢查數控機床內有無雜物。用干燥的壓縮空氣吹凈內部，也可使用吹風機或手風箱等來吹，但不能碰擊的是電動機的繞組。
④ 檢查數控機床的轉軸是否能自由旋轉。對于滑動軸承，轉子的軸向串動量每邊約2-3mm。
⑤ 檢查數控機床軸承是否有油。一般高速電動機應采用高速機油、低速電動機應采用機械油。滾珠軸承常用的潤滑脂為復合鈣基、鈣鈉基脂及鋰基潤滑脂。
⑥ 檢查數控機床接地裝置是否可靠。
⑦ 對新安裝的電動機，應檢查地腳和軸承螺母是否擰緊，以及機械方面是否牢固。檢查電動機機座與電源線鋼管接地情況。
⑧ 經過上述準(zhun)備(bei)工作和檢查(cha)后方，沒有(you)(you)問題(ti)了，就可以啟動數控機床了。電(dian)動機啟動后應空(kong)轉(zhuan)一(yi)段時(shi)間，在(zai)這(zhe)段時(shi)間內(nei)應注意軸承溫(wen)升，不(bu)能超過有(you)(you)關的規(gui)定，而且應該注意是否有(you)(you)不(bu)正常噪聲、振動、局(ju)部發熱(re)等(deng)現(xian)象，如有(you)(you)不(bu)正常現(xian)象需消除后才(cai)能投入正常運行。
