西門子840d（數(shù)控系統(tǒng)）NCK沒電維修開拓創新，專業(yè)技術(shù)，專業(yè)維修必然趨勢，全套測試平臺促進善治，當(dāng)天送機(jī)當(dāng)天修復(fù)。

西門子840d（數(shù)控系統(tǒng)）NCK沒電維修多樣性，NCU/CCU數(shù)控單元常見故障：7段碼指示燈無顯示發揮效力，數(shù)碼管數(shù)字一直跳換閃爍維修，H1明顯、H2全亮服務水平，7段碼顯示8，7段碼數(shù)字翻轉(zhuǎn)數(shù)據(jù)不能總清技術創新，電池處理方法、風(fēng)扇故障，數(shù)據(jù)不能保持持續向好，接口故障習慣，數(shù)碼管數(shù)字不停閃維修充足，NCU報警，CCU不正常等等故障維修的積極性。
