Embodiment 1

[0020] The specific processing method is as follows:

[0021] a) Rough machining parts, first use the traditional vise clamping device to position and clamp the parts, and then use high-speed cutting processing technology for rough machining to remove excess material from the parts and leave enough margin for finishing. Among them, compared with ordinary cutting, high-speed cutting has fast cutting speed, fast material deformation speed, large strain rate, and is not easy to produce built-up edge and phosphorus thorns, thus ensuring the surface quality of parts; at the same time, due to the fast cutting speed, Most of the cutting heat is taken away by the chips, and the cutting surface has no time to produce plastic deformation, and the milling process has been completed, so that the stress generated during the processing is controlled in a small range, and the dimensional accuracy of the part processing is better guaranteed.

Abstract

The invention provides a thin-walled part machining method. A thin-walled part is an aluminum alloy thin-walled cavity part. The machining method comprises the first step of rough part machining, the second step of thermal processing of the part and the third step of fine part machining. According to the thin-walled part machining method, the machining method is reasonable in procedure arrangement and high in working efficiency; the problem of machining deformation of the part is effectively solved, and the machining precision and the surface quality of the part are greatly improved.

Description

technical field [0001] The invention relates to a part processing method, in particular to a thin-walled part processing method, and belongs to the technical field of mechanical processing. Background technique [0002] In machining, thin-walled parts are widely used in actual production, especially aluminum alloy thin-walled cavity parts are increasingly widely used in the electronics industry. This type of parts is generally processed by aluminum alloy plate as a whole, which has the advantages of light weight and compact structure. However, this type of parts has always had difficulties such as long processing cycle, high processing cost, and difficult control of processing accuracy. The reason is that the processing process of such parts The amount of metal removal is large, the rigidity is low, the strength is weak, and it is easy to produce large deformation. It is difficult to guarantee the processing accuracy and surface quality of the parts after processing. [000...
