Troubleshooting method of NC busbar processing machine

For the repair of the mechanical part of the CNC busbar processing machine, any failure that is the same as the mechanical part of the conventional CNC busbar processing machine can be treated by the mechanical failure handling regulations of the conventional CNC busbar processing machine. However, because the CNC busbar processing machine tools mostly use electrical control, which simplifies the mechanical structure, the mechanical failure rate is significantly reduced.

Because most of the transmission chains of CNC busbar processing machines use rolling friction pairs, most of the failures in this area are caused by the decline in sports quality. For example, the backlash increases, the positioning accuracy cannot meet the requirements, the phenomenon of mechanical crawling, and the bearing noise becomes larger (especially after a mechanical hard collision). This part of the maintenance is often closely related to the adjustment of the pre-tightening force of the kinematic pair, the loose ring and the compensation link.

This part of the fault is mostly related to the automatic tensioning device of the tool holder, the automatic shifting device and the reduction of the accuracy of the spindle movement. Because the CNC bus processing machine adopts electrical automatic speed regulation, the mechanical gearbox device has been cancelled. Sometimes although there is a gearbox, it is also very simple, and the structure is simplified to greatly reduce the failure.

The CNC busbar processing machine is equipped with many limit motion limit switches. After a period of use, the movement characteristics of the moving parts will change, and the mechanical reliability of the press-fit limit switch and the quality and characteristics of the limit switch will affect the whole machine. exercise. This requires good inspection, replacement or adjustment.
