The cutting efficiency of CNC vertical lathe is affected by many factors. Here are some common influencing factors:

1. Cutting parameters: CNC vertical lathe cutting parameters include cutting speed, feed speed and cutting depth. Reasonable selection and adjustment of CNC vertical lathe parameters can effectively improve cutting efficiency. Too high or too low cutting speed and feed speed will affect cutting efficiency and must be adjusted according to the requirements of the processing material and workpiece.
2. Tool selection: Choosing the appropriate tool type, tool material and tool geometry for CNC vertical lathe has an important impact on cutting efficiency. Tools that are suitable for the machining task and material provide higher cutting performance and longer life.
3. Tool condition: The wear and damage of CNC vertical turning tools will directly affect the cutting efficiency. Replace worn tools in a timely manner to ensure the good edge condition of the tools and maintain stable cutting efficiency of CNC vertical lathes.
4. Machine tool rigidity and stability: The rigidity and stability of CNC vertical lathes will affect vibration and deformation during the cutting process, thereby affecting cutting efficiency and surface quality. A high-quality CNC vertical lathe has good rigidity and stability and can provide higher cutting efficiency.
5. CNC system and programming: The stability of the CNC system and the accuracy of programming have a direct impact on cutting efficiency. The fast response and accurate control of the CNC system can increase processing speed and accuracy, while high-quality programming can avoid unnecessary downtime and adjustments.
6. Cooling lubrication: Appropriate cooling lubricant can reduce friction and heat, reduce wear and thermal deformation during the cutting process, thereby improving CNC vertical lathe cutting efficiency and workpiece quality.
7. Workpiece fixing and clamping: Reasonable workpiece fixing and clamping can ensure the stability and rigidity of the workpiece, reduce vibration and deformation, and improve CNC vertical lathe cutting efficiency and processing accuracy.

These factors need to be comprehensively considered according to the specific processing conditions and requirements, and adjusted and optimized according to the actual situation to improve the cutting efficiency of CNC vertical lathes.
