智能制造的大環境下，數控精密加工機床的使用越來越廣泛，運行維護的工作也很艱巨。
機床是制造企業重要的資產，以其精密貴重占有非常重要的地位，必須確保機床運行的平穩性和可靠性。然而機床電器在實際運行過程中經常會出現一些莫名的故障，除了機床自身的老化或者質量原因，定期檢查供電質量，溫度等的巡檢，根據測試結果就可以有計劃的進行檢修維護。
下面分享幾個常見的注意事項
1、供電質量
從用電角度來說，導致用電設備故障或不能正常工作的電壓、電流或頻率偏差等都是電能質量。另外，有些負載在運行時也會影響電網的質量，注入諧波、導致電網電壓波動，影響臨近的負載運行等。
供電質量有問題，除了會影響用電設備的正常和連續運行，也會影響運行效率。機床對供電質量的要求很高，例如電壓幅值隨著負載變化要保證一定的穩定性，否則就會引起各種誤動作，諧波含量不能太大，否則會過熱，降低設備的絕緣性能，還有三相不平衡等。
下面是一個實際的測試案例：
遇到的問題：
德國進口的打磨齒輪箱不見得機床經常出現故障，變頻器里面的部件損壞，維修費用昂貴，而且造成長時停機，耽誤生產和工期
需求：查找導致故障的原因
用戶反映出現變頻器不見損壞的時候發生在機床空載運行時。一般造成電器損壞需要檢查電壓電流幅值及波形。
