  設備調試階段的故障率較高，存在問題較為復雜，其特征是設計、制造、安裝以及管理等問題交織在一起。除機械、電氣問題外，一般液壓系統常見故障有：

 

 

    1)接頭連接處泄漏。

 

    2)運動速度不穩定。

 

     3)閥心卡死或運動不靈活，造成執行機構動作失靈。

 

     4)阻尼小孔被堵，造成系統壓力不穩定或壓力調不上去。

 

     5)閥類元件漏裝彈簧或密封件，或管道接錯而使動作混亂。

 

6)設計、選擇不當，使系統發熱，或動作不協調，位置精度達不到要求。

 

7)液壓件加工質量差，或安裝質量差，造成閥類動作不靈活。

 

8)長期工作，密封件老化，以及易損元件磨損等，造成系統中內外泄漏量增加，系統效率明顯下降。

 液壓傳動系統在數控機床中占有很重要的位置，加工中心的刀具自動交換系統(ATC)，托盤自動交換系統，主軸箱的平衡，主軸箱齒輪的變檔以及回轉工作臺的夾緊等一般都采用液壓系統來實現。

機床液壓設備是由機械、液壓、電氣及儀表等組成的統一體，分析系統的故障之前必須弄清楚整個液壓系統的傳動原理、結構特點，然后根據故障現象進行分析、判斷，確定區域、部位、以至于某個元件。液壓系統的工作是由壓力、流量、液流方向來實現的，可按照這些特征找出故障的原因并及時給予排除。造成故障的主要原因一般不外有三種情況：一是設計不完善或不合理；二是操作安裝有誤，使零件、部件運轉不正常；三是使用、維護、保養不當。前一種故障必須充分分析研究后進行改裝、完善，后兩種故障可以用修理及調整的方法解決
