Thermal deformation of CNC vertical lathes is an important issue that requires attention because it directly affects the machining accuracy and the stability of the machine tool. In order to deal with the thermal deformation of CNC vertical lathes, the following measures can be taken:

1. Reduce fever:

CNC vertical lathes try to separate the heat source from the host machine as much as possible, such as placing the motor, gearbox, hydraulic device, and fuel tank externally.

For CNC vertical lathe heat sources that cannot be separated from the host machine, such as CNC vertical lathe spindle bearings, screw nut pairs, high-speed motion guide rail pairs, etc., their friction characteristics and lubrication conditions should be improved to reduce the heat inside the CNC vertical lathe.

2..Control temperature rise:

The CNC vertical lathe adopts heat dissipation, air cooling, liquid cooling and other methods to control the temperature of heating parts such as the spindle box, hydrostatic guide hydraulic oil, etc.

CNC vertical lathes reduce the impact of heat on machine tools by optimizing the machine tool structure and thermal design, such as thermal symmetry structure, thermal balance measures, etc.

3. Improve machine tool structure:

When designing the CNC vertical lathe, a double-column structure is used to increase the symmetry and rigidity of the CNC vertical lathe structure and reduce thermal deformation.

The CNC vertical lathe optimizes the design of the spindle box so that the thermal deformation of the CNC vertical lathe spindle occurs in the vertical direction of the tool cutting, reducing changes in radial dimensions.

Reduce the distance between the center of the CNC vertical lathe spindle and the bottom surface of the spindle box, and try to make the temperature rise of the front and rear of the CNC vertical lathe spindle box consistent to avoid tilting after deformation of the spindle.

4. Measures for strong cooling of cutting parts:

When the CNC vertical lathe cutting volume is large, multiple nozzles and large flow coolant are used to cool and remove hot chips, and large-capacity circulating coolant or cooling devices are used to control the temperature rise.

To sum up, reducing the thermal deformation of CNC vertical lathes requires comprehensive consideration from many aspects, including reducing heat generation, controlling temperature rise, improving the structure of CNC vertical lathes, and taking strong cooling measures for the cutting parts. The effective implementation of these measures can significantly improve the processing accuracy and stability of CNC vertical lathes.
