The same faults of the mechanical part of the CNC busbar processing machine and the conventional CNC busbar processing machine can be treated according to the provisions on mechanical fault treatment of the conventional CNC busbar processing machine. However, due to the electrical control of CNC busbar processing machine tools, the mechanical structure is simplified, so the mechanical failure rate is significantly reduced.
Because the transmission chain of CNC busbar processing machine mostly adopts rolling friction pair, most of these faults are caused by the decline of motion quality. For example, the reverse clearance increases, the positioning accuracy can not meet the requirements, the mechanical crawling phenomenon, and the bearing noise increases (especially after mechanical hard collision). The maintenance of this part is often closely related to the pre tightening force of the moving pair, the adjustment of the loose ring and the compensation link.
Most of these faults are related to the automatic tensioning device of the tool handle, the automatic shift device and the decline of the motion accuracy of the main shaft. Because the mechanical gearbox device has been cancelled after the CNC busbar processing machine adopts electrical automatic speed regulation. Sometimes there is a gearbox, but it is also very simple. The structure is simplified, which greatly reduces the faults.
The CNC busbar processing machine is equipped with many limit motion travel switches. After being used for a period of time, the motion characteristics of the moving parts have changed, and the mechanical reliability of the crimping travel switch and the quality and characteristics of the travel switch will affect the movement of the whole machine. This requires good inspection, replacement or adjustment.
