Simple Troubleshooting CNC tool

Since the CNC machine tool drive chain mostly rolling friction, so the fault in this area most of the performance degradation caused by motion. Such as backlash increases positioning accuracy is mainly the mechanical creeping phenomenon, bearing noise becomes large (especially after a mechanical hard collision prone) and so on. This part of the regular maintenance and deputy campaign preload, loose ring and adjust the compensation aspects are closely related. 
CNC tool machine is equipped with a lot of movement stroke limit switches, after a period of time, so that the motion characteristics of moving parts from a mass change and mechanical reliability and limit switch limit switch itself lamination, properties will affect the whole movement . This requires a good inspection, replacement, or adjustment. 
This part of the fault more with the handle of the automatic tensioning device, automatically change the file device and spindle motion accuracy drops and so on. Because CNC tool machine automatically take the electric governor has been canceled after mechanical gearbox unit, although sometimes the gearbox, but also very simple, so that failure to simplify the structure greatly reduced.
