数控车床液压系统故障类型分析与研究

Fault Type Analysis and Research on Hydraulic System of NC Lathe

液压系统是数控车床的重要组成部分,主要负责实现卡盘松紧、刀架旋转、套筒伸缩等功能。针对数控车床液压系统常见故障进行总结,分别对因液压系统故障导致的噪声、爬行、冲击等问题展开分析,并提出维修建议,以viva T2C数控车床的液压系统为例,对出现的故障进行实例分析。

Hydraulic system is an important part of the numerical control lathe, which performs such functions as clamping of the chuck, rotating of the tool holder and telescopic of the sleeve. The common faults of hydraulic system of NC lathe are summarized, and the problems of noise, creep and impact caused by hydraulic system fault are analyzed respectively, and put forward the maintenance suggestions. Taking the hydraulic system of viva T2C CNC lathe as an example,case analysis of the occurrence of fault.
