In order to prevent the deformation of the vertical CNC lathe, the following measures can be taken:

1. Material selection: The vertical CNC lathe selects materials with appropriate hardness and strength to manufacture the lathe to ensure that it can withstand the cutting force and other forces during the processing. In addition, the thermal expansion coefficient of the material should also be taken into account to reduce the impact of thermal deformation.

2. Structural design: Optimize the layout and structural design of the vertical CNC lathe, such as using thermal symmetric structure, inclined bed, flat bed and inclined slide structure, etc., to reduce the impact of heat source on the lathe. For heavy CNC machine tools, thermal balance measures can be used to maintain the stability of the machine tool.

3. Control temperature rise: The heat-generating parts of the CNC lathe (such as the spindle box, hydrostatic guide rail hydraulic oil, etc.) are controlled by heat dissipation, air cooling and liquid cooling. This can effectively absorb the heat emitted by the heat source, reduce the temperature of the machine tool, and thus reduce the impact of thermal deformation.

4. Reasonable cutting parameters: The vertical CNC lathe selects appropriate cutting parameters such as cutting speed, feed speed and cutting depth according to the characteristics of the workpiece material and processing requirements. Reasonable parameter selection helps to reduce thermal deformation during cutting, thereby avoiding deformation problems of workpieces.

5. Reasonable clamping method: During the processing of vertical CNC lathes, reasonable clamping methods can effectively prevent deformation of workpieces. It is necessary to pay attention to the uniform distribution and reasonable control of clamping force, and at the same time select suitable fixtures and fixture forms to make them in close contact with the workpiece and effectively fix the workpiece.

6. Use appropriate coolant: During the cutting process of vertical CNC lathes, the appropriate use of coolant can effectively reduce the temperature of the workpiece and reduce thermal deformation during cutting. It is necessary to reasonably select the type and use of coolant and maintain its stability and reliability during processing.

7. Regular inspection and maintenance: Regularly check various parts of the CNC lathe, such as guide rails, spindles, bearings, etc., to ensure that they are in good working condition. At the same time, perform regular maintenance on the machine tool, such as cleaning, lubrication and replacement of worn parts, to extend the service life of the machine tool and maintain its accuracy and stability.

8. Training and operating specifications: Provide professional training for vertical CNC lathe operators to familiarize them with the operating procedures and safe operating procedures of the machine tool. At the same time, establish operating specifications to ensure that operators can use the machine tool correctly and avoid deformation of the machine tool caused by improper operation.

In summary, vertical CNC lathes can effectively prevent deformation of vertical CNC lathes by selecting appropriate materials, optimizing structural design, controlling temperature rise, selecting appropriate cutting parameters, reasonable clamping methods, using appropriate coolants, regular inspection and maintenance, as well as training and operating specifications.
