Brief discussion on the concrete methods of vibration fault of CNC lathe by CNC lathe manufacturers
1. Inspection and troubleshooting of mechanical parts
2. Analyze the fault location
3. Inspection and troubleshooting of feed servo system fault
If the cause of crawling and vibration is the feed servo system, it is necessary to check the relevant links in the servo system respectively. Check the speed regulator, servo motor or tachogenerator, system interpolation accuracy, system gain, whether the system parameters related to position control are set correctly, whether the short-circuit bar on the speed control unit is set correctly, whether the gain potentiometer is adjusted with deviation, and whether the circuit of the speed control unit is in good condition. It is necessary to check and eliminate the following points one by one:
1. Detection of pulse encoder or tachogenerator
2. Motor inspection
3. Detection of feedback signal of speed measuring motor
4. Detection of speed regulator
5. Adjustment of system parameters
6. Treatment of external interference
