What are the techniques for machining thin-walled parts with lathes?

Machining thin-walled parts with lathes

Everyone knows that it is difficult to machine a thin wall in a CNC lathe, especially in the machining of the inner hole. Since the thin wall is subjected to the cutting force during the cutting process, deformation is likely to occur.

5-axis linkage machiningThis leads to the appearance of an ellipse or a small "waist" in the middle. In addition, thin-walled bushings are prone to thermal deformation due to poor heat dissipation during processing, resulting in dimensional and shape errors.
To meet the requirements of the drawings, the important problem to be solved is how to reduce the influence of cutting force on the deformation of the workpiece.
Next, PTJ Manufacturing Shop will bring you together to explore the techniques of machining thin-walled parts with CNC lathes.
The machining of thin-walled parts by CNC lathe is a difficult problem in turning machining. The reason is that the thin-walled parts have poor rigidity and weak strength, and are easily deformed during processing, which makes the shape error of the parts increase, and it is difficult to ensure the processing quality of the parts. The advantages of high machining precision and high production efficiency of CNC lathe can be utilized, and the influence of process problems on the machining quality of the parts can be fully considered. For this purpose, the workpiece clamping, tool geometry parameters and program preparation are tested to effectively overcome The deformation that occurs during the processing of thin-walled parts ensures the machining accuracy and provides a good basis and reference for better processing of thin-walled parts in the future.
No matter what form you use to machine a CNC lathe, you must first start by looking at the part drawing. It can be seen from the drawing that the thin-walled parts are processed easily, and it is easy to produce deformation. Here, not only the clamping is inconvenient, but also the parts to be processed are difficult to process, and a special thin-walled casing and a shaft are required to be designed.
