CNC vertical lathe is a high-precision processing equipment that is widely used in the processing of various mechanical parts and has the characteristics of high efficiency and stability. However, during use, sometimes the CNC vertical lathe cannot adjust the speed, which brings great trouble to the processing. So what is the reason why the CNC vertical lathe cannot adjust the speed? Let me give you a detailed analysis below.

First of all, we need to understand the speed regulation principle of CNC vertical lathe. The spindle motor of the CNC vertical lathe adjusts the motor speed through the frequency converter to achieve different speeds of the workpiece. However, if the CNC vertical lathe cannot adjust the speed, problems often occur in this link. There may be several reasons:

1. Inverter setting problem. If the CNC vertical lathe cannot adjust the speed, it may be because the frequency converter settings are incorrect. Problems such as unstable voltage and uncertain frequency settings may occur, which may cause the spindle motor's speed to be unable to be adjusted stably. To solve this problem, you need to reset the inverter parameters to ensure its normal operation.

2. Motor circuit failure. When using a CNC vertical lathe, if a fault is found in the motor circuit, the speed of the spindle motor will be unstable and cannot be adjusted. Therefore, it is necessary to carefully check the connection status of the motor circuit to ensure that it is normal.

3. There is a problem with the spindle motor. If the CNC vertical lathe cannot adjust the speed, there may be a problem with the spindle motor itself. For example, problems such as damaged motor bearings and broken motor coils will cause the motor to fail to work properly. In this case, timely repairs are required.

4. Feeding system failure. If the feed system fails, the feed speed of the workpiece may not be adjusted, which will also affect the speed adjustment of the spindle motor. Therefore, the feeding system needs to be checked to ensure it is functioning properly.

To sum up, the inability of the CNC vertical lathe to adjust its speed may be caused by a combination of factors. The problems need to be carefully investigated and solved one by one. Only by ensuring the normal operation of every link of the equipment can processing efficiency and processing quality be guaranteed.
