Components of CNC machining center

CNC machining center is an automatic machine tool product composed of mechanical equipment and CNC system that can process complex parts. CNC machining center will encounter some problems in daily use. This is not only in the process of using CNC machining center. Attention should be paid to maintenance and at the same time, it is necessary to pay attention to the operation of the CNC machining center. Do not operate blindly. Below we mainly list some failures in the daily use of the CNC machining center and some simple problems for the failure of the CNC machining center. analysis.

1. The problem of encoder pulse counting error alarm of CNC machine tool machining center

This type of problem is usually displayed on the LED display screen 6, and the PMM screen in the system screen displays 303/304/305/308 alarm. The main cause of failure is that the serial encoder of the servo motor does not calculate the number or the pulse is lost during operation. This type of phenomenon needs to be turned on after shutdown, and the alarm will often disappear. If the alarm has not been canceled, then the motor or feedback cable should be replaced immediately, but if the alarm disappears, it is not too happy. We need to target the CNC machining center. After returning to the reference point, run other commands to debug, the weak PMM308 alarm may be caused by interference, just turn off and on

2. CNC machining center serial center serial encoder communication error alarm

For such problems, we should first check the accuracy of the encoder amplifier of the CNC machine tool machining center CNC motor and the feedback line or whether there is a disconnection phenomenon. If the shield of the motor feedback line is not intact, please go to the manufacturer’s warranty as soon as possible. In CNC machining, the encoder of the motor is connected with the motor, it is best not to disassemble.
