What is the cause of thermal deformation of CNC lathes on inclined bed

Slant bed CNC lathe is a high precision and high efficiency automatic machine tool. Equipped with multi-station turret or power turret, the machine tool has a wide range of processing performance, can process linear cylinders, slant cylinders, arcs and various complex workpieces such as threads, slots, worms, with linear interpolation, arcs Interpolate various compensation functions, and play a good economic effect in the mass production of complex parts.

In order to ensure the working accuracy of the CNC lathe of the inclined bed and extend the service life, it is necessary to carry out reasonable maintenance work on the CNC lathe of the inclined bed. The quality of the lathe maintenance directly affects the processing quality and production efficiency of the workpiece.

In the working process of the inclined bed CNC lathe, if thermal deformation occurs, it will affect the accuracy of the inclined bed CNC lathe. In general, the thermal deformation of the inclined bed CNC lathe is mainly due to the rapid movement of the table and the tool holder of the inclined bed CNC lathe on the guide surface. The friction between the two generates a lot of heat.

Lathe guide rail thermal deformation. In addition, the movement between the spindle of the CNC lathe of the inclined bed and the rolling bearing will generate frictional heat, which will cause the thermal deformation of the spindle of the CNC lathe of the inclined bed; or the friction heat between the ball and the nut of the CNC lathe of the inclined bed will cause the inclined bed Thermal deformation of the guide rail of the CNC lathe. In short, the thermal deformation of the CNC lathe on the inclined bed is mainly caused by the heat generated by the friction between the parts.
