HNC-21T四方刀架电气故障排查与处置的探讨

摘要

The failure of 4-position turret is one of the common faults in CNC lathe using the HNC-21 system.Based on analysis of the control principle of the automatic tool changer, the paper investigates into the electrical causes of turret common faults and puts forward the corresponding solutions, which can be used for the repairment of similar faults.%对使用HNC-21T系统的数控车床而言，其四方刀架的故障是常见故障之一。在分析其自动换刀控制原理的基础上，对刀架常见故障现象进行以电气故障为主的排查，并提出了相应的处置建议，为同类故障的维修处理提供了可以借鉴的经验。
