Machining method for thin-wall circular ring part

Abstract

The invention provides a machining method for a thin-wall circular ring part. According to the method, a procedure of eliminating internal stress annealing is added in the machining process, the cutting machining performance is improved, and stress deformation in the machining process is eliminated; and meanwhile, end face pressing is adopted when a workpiece is clamped, and clamping deformation of the workpiece and vibration in the machining process are avoided. According to the machining method, a 90-degree tool cutting edge angle tool is used for machining, generation of cutting heat and vibration in the cutting process are reduced, and therefore thermal deformation is reduced, the surface roughness and the size precision of the workpiece are improved, machining deformation of the partis well controlled, and the machining quality and the machining efficiency of products are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing method for thin-walled circular parts. Background technique [0002] As shown in the figure, a typical thin-walled annular part is made of copper alloy. This part has low strength and thin wall thickness. During the processing, it is easy to produce clamping and processing deformation. It is a difficult problem in turning processing. The conventional processing method of this part is to directly drill holes with round bars and rough them , Finish car end face, outer circle and inner hole of each gear, and then cut off, and finally use the three-jaw clamping method to clamp the rough and finish car end face to the total length requirement. The reject rate of products processed by this processing method is extremely high, and the reasons are as follows: [0003] 1. It is easy to deform under the action of clamping force, which affects the di...

AI Technical Summary

Problems solved by technology

[0003] 1. It is easy to deform under the action of clamping force, which affects the dimensional accuracy and shape accuracy of the workpiece;

[0004] 2. Cutting heat will cause thermal deformation of the workpiece, making it difficult to control the size of the workpiece;

[0005] 3. Under the action of cutting force (especially radial cutting force), it is easy to generate vibration and deformation, which affects the dimensional accuracy, shape, position accuracy and surface roughness of the workpiece

[0006] To sum up, the thin-walled part has poor rigidity, weak strength, high metal removal rate in the existing processing method, and is easily deformed during processing, which increases the shape and position error of the part and makes it difficult to guarantee the processing quality of the part
