Machine tool equipment electrical troubleshooting

 Machine tool equipment failure phenomena in terms of electrical performance, sometimes sometimes in the aspect of mechanical performance, even in the aspect of hydraulic performance. When we to repair machine tool equipment failure, as long as the master machine tool equipment electrical troubleshooting methods commonly used, the machine tool equipment of mechanical and electrical contact fully understand, electricalmotor1.blogspot.com find out action principle, often can successfully troubleshooting. Repairers are divided into some factories electrical maintenance electrical motor and mechanical maintenance man, when the machine tool equipment failure is often confuse the responsibility of the electrical maintenance man or mechanical maintenance responsibility, caused the phenomenon of wrangling with each other. Such as a few years ago in a new plant old radial drilling machine appeared the rocker arm and the failure of the mast lock is not tight, cause can't normal drilling. 

The drill machine lock system is: mechanical, hydraulic + locking process of it is by the first lock motor diesel generating driven initially lock locking mechanism, reach place, again by the hydraulic institute for further lock rocker arm. Began to suspect that is locking mechanism caused by mechanical wear lock is not tight. Will arrange mechanical maintenance man to repair, but they cannot solve the problem. Then arrange electric mechanic repairs and they said lock motor function also drives the locking mechanism for locking action, is not their responsibility; Back wheel mechanical maintenance technician for maintenance, check the hydraulic mechanism and locking mechanism are no abnormal phenomenon. Finally careful maintenance maintenance electrician's turn again, only to find that is due to mechanical locking process not to switch the collision. Because only the collision to the position switch contacts, the corresponding 220v ac electric motors electromagnetic valve electric action, hydraulic mechanism to further lock rocker arm. Adjust the position of the position switch failure to get out. As a maintenance electrician, machine tool equipment of mechanical and electrical contact to fully understand, find out action principle, in order to improve the work efficiency and ensure the quality of maintenance. I, the author discuss electrical troubleshooting methods commonly used machine tool equipment.
