CNC bus processing machine mechanical parts of the repair, and conventional CNC bus processing machine mechanical parts of the same fault can be conventional CNC bus processing machine mechanical fault treatment provisions. However, due to the numerical control bus processing machine tool mostly adopts electrical control, so that the mechanical structure is simplified, so the mechanical failure rate has been significantly reduced. Because the transmission chain of CNC bus processing machine mostly uses rolling friction pair, so this aspect of the fault is mostly caused by the decline of motion quality. Such as the increase of reverse clearance, positioning accuracy can not meet the requirements, mechanical crawling phenomenon, bearing noise increases (especially after mechanical hard collision is easy to produce). The maintenance of this part is often closely related to the adjustment of preload, loose ring and compensation link of the moving pair. This part of the fault is mainly related to the automatic tensioning device of the tool handle, the automatic shift device and the decrease of the movement accuracy of the spindle. Because CNC bus processing machine to take the electrical automatic speed control has been canceled the mechanical transmission device, sometimes although there is a gearbox but also very simple, the structure is simplified to reduce the fault.
