電網(wǎng)電壓過高或者過低，系統(tǒng)就會產(chǎn)生電壓過高報警或者過低報警；切削量過大時，就會產(chǎn)生過載報警等。一臺采用SINUMERIK81系統(tǒng)的數(shù)控機床在加工過程中，系統(tǒng)有時自動斷電關(guān)機，重新啟動后，還可以正常工作。根據(jù)系統(tǒng)工作原理和故障現(xiàn)象懷疑故障原因是系統(tǒng)供電電壓波動，測量系統(tǒng)電源模塊上的24V輸人電源，發(fā)現(xiàn)為22.3V左右，當(dāng)機床加工時，這個電壓還向下波動，特別是切削量大時，電壓下降就大，有時接近21V，這時系統(tǒng)自動斷電關(guān)機，為了解決這個問題，更換容量大的24V電源變壓器將這個故障消除。

鉆孔鉆孔首先是要盡可能減少冷作硬化。在鉆孔前，建議不要沖孔，因為沖孔會使鉆孔的表面產(chǎn)生冷作硬化。采用中心鉆，如果不能使用中心鉆，就用樣沖沖中心孔。同樣，當(dāng)使用手動進給鉆進時，要緊的是不能使鉆進中斷，而且鉆壓要保持均勻連續(xù)。應(yīng)使用高速鋼麻花鉆，為了防止產(chǎn)生摩擦，鉆頭要保持鋒利，關(guān)于切削角、前角、后隙角和切削速度應(yīng)按制造廠說明。成型絕大多數(shù)成型技術(shù)通用于所有金屬。主要區(qū)別仍是不銹鋼強度更高和它的冷作硬化特性。
