The speed of CNC vertical lathe has a significant impact on processing. The choice of rotation speed is directly related to cutting force, cutting temperature, workpiece centrifugal force and machine tool vibration. These factors jointly determine the quality and efficiency of processing.

First, the CNC vertical lathe speed affects the cutting force. Excessively high rotational speed will lead to increased cutting force, which will intensify the wear of the machine tool and may even cause bearing damage. This will not only reduce the service life of the machine tool, but may also affect the accuracy and stability of processing.

Secondly, the CNC vertical lathe speed will also affect the cutting temperature. After exceeding a certain speed range, the cutting temperature will increase significantly. This may not only affect the life and performance of CNC vertical turning tools, but may also have a thermal impact on the workpiece material, causing workpiece deformation or thermal cracks.

In addition, the CNC vertical lathe speed also affects the centrifugal force of the workpiece. When the CNC vertical lathe rotates at high speed, the centrifugal force on the workpiece will increase, which may cause the CNC vertical lathe workpiece to vibrate during processing or deviate from the preset processing trajectory, thus reducing the processing accuracy.

Finally, the choice of CNC vertical lathe speed also directly affects the vibration of the machine tool. Unreasonable rotational speed may cause the machine tool to resonate, which will not only affect the machining accuracy, but may also cause damage to the overall structure of the CNC vertical lathe.

To sum up, the speed of CNC vertical lathe has many effects on processing. Therefore, in the actual processing process, the rotation speed needs to be reasonably selected based on factors such as the workpiece material, processing requirements, and machine tool performance to ensure the quality and efficiency of processing. At the same time, attention should also be paid to regular maintenance and upkeep of machine tools to ensure their long-term and stable operation.
