CNC lathes are mainly used for the inner and outer surfaces of disk parts or outer circular surfaces of shaft parts, inner and outer conical surfaces of arbitrary cone angles, complex inner and outer surfaces rotating and cylindrical, conical threads and other cutting processes, And can carry out grooving, drilling, reaming, reaming. Today we mainly talk about how to reduce the thermal deformation of the CNC Lathe spindle.
1.Heat insulation, keep the heat source away from the main shaft, such as motor, transmission isolation, separation transmission, etc.
2.Heat dissipation, strengthen lubrication cooling, oil cooling, air cooling and other methods to speed up heat dissipation.
3.Reduce the heat source, focus on adjusting the spindle bearing speed, clearance and reasonable preload. 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 frictional heat generation of some parts.
4.In order to reduce the influence of thermal deformation, no matter what method is used, 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.
