When performing small and medium-sized CNC vertical lathe processing, the following are some aspects that need attention:

1. Select appropriate machine tools and tools: According to the size, material and precision requirements of the processed parts, select suitable small and medium-sized CNC vertical lathe machines and cutting tools. Make sure to choose ones with sufficient stiffness and stability, as well as proper power and precision.
2. Optimize the processing plan of the parts: Before the CNC vertical lathe processing, carry out reasonable process planning and tool path design, and optimize the processing plan. Considering factors such as processing efficiency, cutting force, cutting heat and surface quality, select the appropriate tool, feed rate and cutting parameters.
3. Accurate machine tool setting and clamping: ensure accurate machine tool setting for small and medium-sized CNC vertical lathes, including adjustment of auxiliary devices, positioning of tools and precise positioning of fixtures. Ensure stable clamping of parts and correct workpiece coordinate system to ensure machining accuracy and consistency.
4. Prevent vibration and resonance: Small and medium-sized CNC vertical lathes are easily affected by vibration and resonance during processing, which affects processing quality and tool life. The risk of vibration and resonance can be reduced by selecting appropriate cutting parameters, reducing cutting shock, and optimizing tool paths and machining strategies.
5. Strict monitoring and quality control: Strict monitoring and quality control of the processing process, including real-time monitoring of dimensions, surface quality and geometry using measuring tools, to ensure processing results that meet the requirements.
6. Do a good job in safety and maintenance: small and medium-sized CNC vertical lathes should pay attention to safety during operation, and abide by relevant operating procedures and safe operation requirements. Carry out regular maintenance and maintenance of machine tools to ensure the normal operation and long-term stability of the equipment.

To sum up, small and medium-sized CNC vertical lathe processing needs to comprehensively consider factors such as process planning, machine setting, tool selection, processing parameter optimization, quality control, and safety maintenance. Reasonable planning and careful execution can improve processing efficiency, ensure processing quality, and extend the service life of machine tools.
