To avoid deformation of vertical CNC lathes, the following measures can be taken:

1. Choose high-quality machine tools: CNC lathes choose high-quality vertical CNC lathes with good rigidity and stability, which can reduce the deformation of machine tools during processing.

2. Reasonable layout of workpieces and fixtures: When CNC lathes clamp workpieces, the fixture layout should be reasonably designed to ensure that the workpieces are clamped firmly and evenly, and reduce deformation caused by improper workpiece clamping.

3. Reduce cutting force: CNC lathes reasonably select tools, cutting parameters and cutting strategies, control cutting force and cutting temperature, and avoid excessive cutting force affecting the machine tool structure.

4. Avoid excessive cutting: CNC lathes avoid excessive cutting during processing, especially when processing workpieces with high rigidity requirements, the cutting depth and feed speed should be controlled to prevent excessive load from causing deformation of the machine tool.

5. Regular maintenance and care: CNC lathes regularly maintain and care for vertical CNC lathes to maintain the accuracy and performance of various parts of the machine tool, and promptly discover and repair problems that may cause deformation.

6. Control the ambient temperature and humidity: The CNC lathe maintains the stability of the processing environment, controls the changes in temperature and humidity, and avoids the impact of environmental factors on the machine tool structure.

7. Strengthen operation training: The CNC lathe provides professional training for operators, teaches them the correct operation methods and precautions, and avoids the deformation of the machine tool caused by improper operation.

Through the comprehensive application of the above measures, the deformation of the vertical CNC lathe can be effectively avoided, and the processing quality and long-term stability of the machine tool can be guaranteed.
