摘要
曲轴车间数控加工机床多采用西门子数控系统,包含820D、840C、840D等数控系统,经常出现控制环硬件故障。为不影响生产,维修过程中常采用将全闭环改为半闭环的检修方法。此种方法可缩短机床故障修理时间,减少不必要的经济损失。
The Siemens CNC system has been mostly adopted in the NC machine of crankshaft workshop, including 820D, 840C, and 840D CNC system. The fault of control loop hardware has been always happened. In order to not affect the production, the semi closed loop repairing method has been selected instead of full closed loop during the repairing process. Thus in this way, the repair time for machine tool fault has been shortened. The working efficiency has been improved, which can satisfy the production demands and reduce the economic loss.
