Abstract:In this paper, servo tool CNC lathe tool can't be changed tower as an example, introduces the CNC lathe servo turret principle, according to the fault phenomena, from the servo turret involving electrical, hydraulic and mechanical aspects of a detailed analysis of the fault type servo turret analysis method and put forward the effective diagnosis method of hydraulic cylinder the fault, focusing on the repair of the preparatory work before (detection, such as the original precision repair before drawing turret wiring diagram), turret and key points of dismantling and assembling, and summarized the turret in the repair process should pay attention to such as cleaning, seal check, use special tooling and use compressed air testing experience.
Key words:servo turret;CNC;fault treatment
