How to reduce thermal deformation of spindle in CNC lathe

1. Reduce the heat source, pay attention to the main extraction bearing speed, adjust and reasonably preload. For thrust bearings and cylindrical roller extraction, due to their poor working conditions, thrust angular contact ball bearings can be used to replace heat when necessary to minimize the friction of certain parts.

2 Insulation to keep the heat source away from the spindle, such as motor and transmission isolation, using separate transmission. 3. Heat dissipation, strengthen lubrication cooling, oil cooling, air cooling and other methods to accelerate heat dissipation.

Reducing the impact of thermal deformation. No matter what method is used, it can only reduce thermal deformation. It is difficult to completely eliminate thermal deformation. Therefore, measures should also be taken to reduce the impact of thermal deformation.
