Information

CNC lathes are mainly used for inner and outer outer surfaces of shaft parts or disk parts, inner and outer conical surfaces with arbitrary cone angles, complex inner and outer surface rotation and cylindrical, conical threads and other cutting processes, And can perform slotting, drilling, reaming, reaming and boredom. Today we mainly talk about how to reduce the thermal deformation of the CNC lathe spindle.

1. Reduce the heat source, focus on adjusting the spindle bearing speed, clearance and reasonable pre-tightening. For thrust bearings and tapered roller bearings, due to their poor working conditions and high heat generation, if necessary, thrust angular contact ball bearings can be used instead to minimize the friction and heat generation of certain parts.

2. Heat insulation, keep the heat source away from the main shaft, such as motor, transmission isolation, separate transmission, etc.

3. Heat dissipation, strengthen lubrication cooling, oil cooling, air cooling and other methods to speed up heat dissipation.

4. In order to reduce the influence of thermal deformation, no matter what method is adopted, it can only reduce thermal deformation, and it is difficult to completely eliminate thermal deformation. Therefore, measures should be taken to reduce the effects of thermal deformation.
