To improve the work efficiency of CNC vertical lathe, the following measures can be taken:

1. Optimize the processing program: Reasonably write and optimize the processing program of the CNC vertical lathe to ensure the accuracy and efficiency of the cutting trajectory and parameters. The optimized processing program can make the machine tool complete the processing task in the shortest time and improve work efficiency.
2. Reasonable selection of cutting tools and cutting parameters: According to different workpiece materials and shapes, select appropriate cutting tools and cutting parameters. Reasonable selection of cutting speed, feed speed, cutting depth and other processing parameters can effectively reduce processing time and improve processing efficiency.
3. Optimize the clamping scheme: design and select the appropriate fixture, and ensure that the clamping force is uniform and firm, reducing the movement and deformation of the workpiece during processing. A reasonable clamping scheme can improve processing stability and work efficiency.
4. Automated operation: The use of automated equipment and systems, such as automatic tool changing systems and automatic loading and unloading devices, can reduce manual intervention and operating time and improve work efficiency. Automated operation can also reduce human error and improve machining accuracy.
5. Regular maintenance and maintenance: regularly maintain and maintain the CNC vertical lathe to maintain the normal working condition and performance of the machine tool. Replace severely worn tools and parts in time to ensure the stability and accuracy of the machine tool and avoid downtime and delays caused by machine tool failures.
6. Continuous learning and training: maintain the technical level and knowledge update of operators, and participate in relevant training courses and training activities. Understand the latest CNC technology and processing methods, master operating skills and troubleshooting methods, and be able to operate and manage CNC vertical lathes more efficiently.

Through the comprehensive application of the above measures, the working efficiency of CNC vertical lathe can be improved, and the processing quality and production efficiency can be improved.
