The cause of jitter when the CNC vertical lathe moves quickly may involve many aspects. First of all, from a mechanical point of view, CNC vertical lathes may be caused by transmission clearance, elastic deformation, friction resistance and other factors. These factors may cause instability in mechanical parts when moving quickly, causing jitter.

Secondly, problems with the CNC vertical lathe servo system may also cause the CNC vertical lathe to shake when it moves quickly. The servo system is responsible for controlling the movement of the machine tool. If its relevant parameters are set improperly, such as unstable output voltage of the position loop, vibration caused by the speed loop, voltage output distortion caused by excessive adjustment of the servo system, etc., vibration or jitter may occur. In addition, problems with the transmission mechanism, such as excessive lead screw clearance, may also cause vibration.

In addition, if the speed setting of the CNC vertical lathe spindle is incorrect, it may also cause jitter during rapid movement. At this time, you need to check whether the spindle speed limit in the parameters is set normally, and whether the connection between the transmission ratio and the spindle encoder is normal.

Finally, the vibration problem of CNC vertical lathe may also be related to factors such as feed speed, motor, detector, system interpolation accuracy and detection gain. If the vibration period changes proportionally to the feed speed, it may be due to a problem with the machine tool, motor or detector; if it is not proportional and roughly fixed, it may be that the system parameters related to position control are set incorrectly, or the speed control unit settings issue.

To sum up, the causes of jitter when a CNC vertical lathe moves rapidly may involve many aspects such as machinery, servo system, spindle speed setting, and machine tool vibration. In order to solve this problem, these factors need to be considered comprehensively, and corresponding inspections and adjustments must be made. If the problem persists, it is recommended to contact professional machine tool maintenance personnel or the manufacturer for further diagnosis and repair.
