摘　　要：通过深入分析具有交换工作台的卧式加工中心在用户现场的故障数据,找出影响机床整机可靠性的故障部位、模式及原因,并对可交换工作台加工中心的故障模式、部位及原因进行了深入分析。找出了机床故障发生的高频子系统,确定了加工中心的可靠性薄弱环节,并据此提出提高国产卧式加工中心机床可靠性的措施,为加工中心进行进一步的可靠性设计提供了依据。By analyzing the failure datum of horizontal machining centers with exchange worktable from the customer locales,the failure parts, modes and causes which impacted the reliability of the machines severely were found. Failure mode, parts and reasons are analyzed deeply of machining center with exchange worktable. Hereby a series of measures to elevate the reliability of the homemade horizontal machining centers were brought forward, so as to provide basis for the reliability design of machining center.
