Skills of machining thin-walled parts on CNC lathe

Because it is difficult to process thin walls on CNC lathes, especially the processing of inner holes, the thin walls are prone to deformation due to the cutting force during the cutting process. This leads to an oval or a "waist shape" with a small middle and large ends. In addition, thin-walled bushings are prone to thermal deformation due to poor heat dissipation during processing, resulting in size and shape errors. The important problem that needs to be solved if the drawing requirements are not met is how to reduce the influence of cutting force on the deformation of the workpiece.

The processing of thin-walled parts on CNC lathes is a difficult problem in turning. The reason is that thin-walled parts have poor rigidity and weak strength, and are extremely easy to deform during processing, which increases the shape and position error of the parts and it is difficult to ensure the quality of the parts. The characteristics of high machining accuracy and high production efficiency of CNC lathes can be used, and the influence of process problems on the quality of parts processing can be fully considered. For this purpose, it is effective to test the clamping of the workpiece, the geometric parameters of the tool, and the programming of the program. To overcome the deformation in the processing of thin-walled parts, ensure the machining accuracy, and provide a good basis and reference for better processing of thin-walled parts in the future.

Regardless of what form the CNC lathe uses to process parts, first of all, you must start by looking at the part drawing. It can be seen from the figure that the thin-walled parts are easily deformed when they are processed. Not only is it inconvenient to clamp, but the parts to be processed are also difficult to process. It is necessary to design a special thin-walled casing and shaft guard.
