How does vertical machining center manufacturer deal with FANUC system overload failure?
At present, most of the domestic high-end CNC machining centers use the FANUC system. Due to the difference in the material of the workpiece and the processing tools, there will always be overload. Generally, the CNC machine tool will have an alarm indicator when it is overloaded. This article will fully introduce it. This kind of failure: the CNC machining center supporting FANUC system, the overload alarm occurs during processing, the alarm number is 434, the manifestation is that the Z-axis motor current is too large, the motor heats up, and the alarm disappears after stopping for about 40 minutes, and then work for a while, and then Similar alarms appear. Analysis and processing process: After checking that the electrical servo system is not faulty, it is estimated that the load is too heavy and it is not moving.
When encountering a system failure, it is better to solve it. Generally, it is enough to refer to the CNC machining center system manual. Of course, the premise is to distinguish between electrical failures and mechanical failures. To distinguish between these two types of failures, the Z-axis motor must be removed from the machine. The fault will no longer appear when it is disconnected and re-run. It is confirmed that the mechanical screw or the moving part is too tight. After adjusting the Z-axis screw anti-loosening nut, the effect is not obvious, and then adjusting the Z-axis guide rail insert, the load of the machine tool is significantly reduced, and the fault is eliminated.
The FANUC system is a relatively common system, and it is also a system that has been used for a long time. The system is relatively stable, but don’t worry when there is a failure. You must carefully find out the cause of the failure. Only in this way can you create greater profits. .
