The speed of CNC vertical lathe has some effects on processing, including:

1. Processing quality: The choice of CNC vertical lathe speed will directly affect the surface quality and dimensional accuracy of the workpiece. At high speeds, the CNC vertical lathe cutting speed increases, which can improve cutting efficiency, but it can also easily cause vibration and resonance, affecting the processing quality. At low speeds, processing can be more stable, but cutting efficiency is lower. Therefore, the appropriate CNC vertical lathe speed needs to be selected based on the specific material, workpiece and processing requirements.
2. Cutting force: The increase in CNC vertical lathe speed will lead to an increase in cutting force. The large cutting force generated at high rotation speed may cause damage to the workpiece and tool, and even cause vibration and instability of the machine tool. Therefore, when determining the CNC vertical lathe speed, the impact of cutting force on the machine tool and workpiece needs to be considered.
3. Cutting temperature: The choice of CNC vertical lathe speed will also affect the generation of cutting temperature. High rotational speed will lead to higher cutting speed, and the friction heat generated during the cutting process will also increase. If the cutting temperature is too high, it may cause problems such as increased tool wear, shortened tool life, and reduced workpiece surface quality. Therefore, when selecting the CNC vertical lathe speed, it is necessary to consider the balance between cutting speed and cutting temperature.
4. Cutting vibration: The increase in CNC vertical lathe speed will increase the risk of vibration during the cutting process. Cutting vibration will not only affect the quality of CNC vertical lathe processing and the surface finish of the workpiece, but may also cause problems such as tool breakage and unstable cutting. Therefore, for workpieces or processing situations that are prone to vibration, it is necessary to appropriately reduce the CNC vertical lathe speed to reduce the impact of vibration.

To sum up, choosing the appropriate CNC vertical lathe speed requires comprehensive consideration of factors such as processing quality, cutting force, cutting temperature and cutting vibration. Conduct trial processing and adjustments according to specific materials, workpieces and processing requirements, and find the best speed range through practical experience and optimized parameters to achieve good processing results. During use, the speed also needs to be adjusted and optimized in time according to the actual situation.
