The long axis of the CNC lathe is generally not the slender shaft of the car. Only the tail can be processed. Below we will talk about the processing method of the slender shaft. The so-called slender shaft generally refers to the length to diameter ratio of more than 25. For parts, general processing of slender shafts use the following three methods:

1. With the tool holder: the purpose of selecting the tool holder is to offset the influence of the radial cutting force on the workpiece during machining, and to reduce the deformation of the cutting oscillation and the rigidity of the workpiece. It is necessary to ensure the center of the bed when using the tool holder. Consistent with the center of the tool holder, since the characteristics of the tool holder are not applicable to the workpiece that requires secondary turning, only one vehicle can be in place;

Hydraulic center frame

2.Hydraulic center frame: The hydraulic center frame can be used to make a support point at the midpoint of the chuck and the tailstock during processing, so that the three-point support can support the deformation caused by the rigidity problem in the middle of the workpiece, thus ensuring The precision in the long axis machining also solves the problem that the tool holder cannot be turned twice;

3. Selecting the heart-shaped meter processing: For the parts with high processing precision below 32 diameter, it is recommended to use the heart-shaped meter processing, and the long bar material processing can be used for one-time molding, saving people, high efficiency and high precision.

The above is the solution for processing slender shaft parts. If you have any questions or need to purchase, please contact us.
