To improve the processing efficiency of small CNC vertical lathes, the following measures can be taken:

1. Optimize the process flow: Find and eliminate bottlenecks and unnecessary steps by analyzing the CNC vertical lathe processing process. Optimizing the process flow can reduce processing time and procedures and improve production efficiency.
2. Reasonable selection of cutting tools and cutting parameters: Choose appropriate cutting tools and cutting parameters for CNC vertical lathes to make the cutting process stable and efficient. According to the workpiece material, processing requirements and cutting conditions, select the appropriate tool material, tool geometry, cutting speed, feed speed and other parameters.
3. Automation and mechanization: The introduction of automated equipment and mechanized systems, such as automatic loading and unloading systems, automatic tool changing systems, etc., can reduce manual intervention and improve production efficiency and consistency.
4. Reasonably arrange process layout: Design reasonable workstation layout and material flow paths to reduce workpiece movement and waiting time and optimize production efficiency.
5. Efficient programming and operation: CNC vertical lathe performs efficient programming and operation, reduces program writing and adjustment time, and ensures that operators are familiar with the machine tool control system and operating procedures.
6. Regular maintenance and maintenance: Regularly inspect and maintain machine tools, including lubrication systems, cooling systems, transmission systems, etc., to ensure normal operation and optimal performance of machine tools.
7. Formulate production plans and schedules: Develop reasonable CNC vertical lathe production plans and schedules, arrange production tasks according to priorities and process requirements, and ensure rational utilization of resources and maximization of production efficiency.
8. Continuous improvement and training: Continuously carry out process improvements, equipment updates and employee training, introduce advanced technology and knowledge, and improve the efficiency and quality of small vertical lathe processing.

The comprehensive application of the above measures can effectively improve the processing efficiency of small CNC vertical lathes. However, specific measures should be evaluated and selected based on actual circumstances and needs to ensure their applicability and feasibility.
