 设备调试阶段的故障率较高，存在问题较为复杂，其特征是设计、制造、安装以及管理等问题交织在一起。除机械、电气问题外，一般液压系统常见故障有：

 

 

    1)接头连接处泄漏。

 

    2)运动速度不稳定。

 

    3)阀心卡死或运动不灵活，造成执行机构动作失灵。

 

    4)阻尼小孔被堵，造成系统压力不稳定或压力调不上去。

 

    5)阀类元件漏装弹簧或密封件，或管道接错而使动作混乱。

 

6)设计、选择不当，使系统发热，或动作不协调，位置精度达不到要求。

 

7)液压件加工质量差，或安装质量差，造成阀类动作不灵活。

 

8)长期工作，密封件老化，以及易损元件磨损等，造成系统中内外泄漏量增加，系统效率明显下降。

液压传动系统在数控机床中占有很重要的位置，加工中心的刀具自动交换系统(ATC)，托盘自动交换系统，主轴箱的平衡，主轴箱齿轮的变档以及回转工作台的夹紧等一般都采用液压系统来实现。

机床液压设备是由机械、液压、电气及仪表等组成的统一体，分析系统的故障之前必须弄清楚整个液压系统的传动原理、结构特点，然后根据故障现象进行分析、判断，确定区域、部位、以至于某个元件。液压系统的工作是由压力、流量、液流方向来实现的，可按照这些特征找出故障的原因并及时给予排除。造成故障的主要原因一般不外有三种情况：一是设计不完善或不合理；二是操作安装有误，使零件、部件运转不正常；三是使用、维护、保养不当。前一种故障必须充分分析研究后进行改装、完善，后两种故障可以用修理及调整的方法解决
