Problems solved by technology
[0002] like figure 2 and image 3 As shown, the traditional thin-walled parts with long wire diameter ratio mainly undergo two processes of rough turning and finishing turning. Among them, after the rough turning of the parts, a margin of 0.3-1mm is reserved on both sides for the next finishing turning process. When the margin is too large, the force between the product and the tool increases, and the resulting thermal stress increases, resulting in product processing deformation; Thermal stress causes parts to deform

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0021] Such as figure 1 As shown, the finished product of the long-diameter-ratio-thin-wall part of the present invention is a hollow cylinder with a wall thickness of 0.03mm and a length of 6.985mm. The traditional processing technology will cause the product to bend and deform, which cannot meet the product requirements.
[0022] Such as Figure 4 with Figure 5 As shown, the present invention proposes a turning-milling composite processing method for long wire-diameter ratio thin-walled parts, which is characterized in that it includes the following steps:
[0023] Step SS1: using a turning tool to perform rough turning on the rotating long-diameter-ratio thin-walled part blank to obtain ...

The invention discloses a turning and milling composite machining method for a thin-wall part with a long linear-diameter ratio. The method is characterized by comprising the following steps: 1, roughly turning a blank of the rotating thin-wall part with the long linear-diameter ratio by using a turning tool to obtain a semi-finished product of the thin-wall part with the long linear-diameter ratio; and 2, milling the semi-finished product of the thin-wall part with the long linear-diameter ratio obtained in the step 1 by using a milling cutter to obtain a finished product of the thin-wall part with the long linear-diameter ratio. The method completely solves the technical problems that the stress between a product and a cutter is increased due to excessive allowance and the generated thermal stress is increased when a traditional thin-wall part with the long linear-diameter ratio is turned and machined so as to result in machining deformation of the product, namely, the deformation ofthe part is caused by overlength of the linear-diameter ratio and the thermal stress generated by the friction between the cutter and the part in the machining process.
Description
technical field [0001] The invention relates to a turning-milling composite processing method for a thin-walled part with a long line-diameter ratio, and belongs to the technical field of mechanical processing. Background technique [0002] Such as figure 2 with image 3 As shown, the traditional thin-walled parts with long wire diameter ratio mainly go through two processes of rough turning and finishing turning. Among them, after the rough turning of the parts, a margin of 0.3-1mm is reserved on both sides for the next finishing turning process. When the margin is too large, the force between the product and the tool increases, and the resulting thermal stress increases, resulting in product processing deformation; Thermal stress causes parts to deform. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, solve the above technical problems, and propose a turning-milling composite processing method for thi...
