A CNC lathe produced by a machine tool factory continuously experiences stepper motor and stepper drive failures in one user. The same CNC lathe has no similar faults at other users. On-site inspection of machines that have failed continuously has found that the cutting fluid at the end of the stepper motor is an important cause of stepper motor and stepper drive failure. The solution to the problem is simple. Simply change the shield on the outside of the stepper motor and the cutting fluid will not enter the motor shaft end. The machine tool factory immediately took measures to modify the design on the one hand, and modified the machine tool cover that had been manufactured on the one hand, effectively preventing more such failures from occurring. The CNC milling machine produced by a machine tool factory continuously damages the communication port at a certain user. At the beginning, the service personnel of the machine tool factory thought that there was a problem with the quality of the products and asked for someone to solve them. From product performance analysis, communication port damage and power plugging or unplugging communication cable, I pay special attention to the user to insert or unplug the communication cable before each fault or cut off the power of the machine when plugging and unplugging, and carefully check When the machine is grounded, it is found that the machine is not properly grounded, and sparks can be seen when the user plugs in and out the communication cable, so that the communication port is of course damaged. After discovering the cause of the fault, it is recommended that the user equip each machine with an isolator and pay attention to cut off the power when plugging and unplugging the cable. As a result, the user has not experienced any similar failure in the next year or more. The CNC lathe produced by a machine tool factory has continuous system failures at the end user. After each new spare part is replaced, it will be faulty after less than one week. The phenomenon is that the yellow screen has no content after booting.
