Machining method of T4 aluminum alloy thin-walled disk-shaped part

Abstract

The invention provides a machining method ofa T4 aluminum alloy thin-walled disk-shaped part, which comprises the steps that a cylindrical blank is provided, a lathe is used for cutting a blank and reserving rough machining allowance, a milling machine is used for milling a workpiece and reserving finishing allowance, the workpiece is subjected to aging treatment, the workpiece is calibrated, thelathe is used for finishing the excircle surface and the two end surfaces of the workpiece, and the milling machine is used for machining various shape features on both end surfaces of the workpiece.According to the machining method ofthe T4 aluminum alloy thin-walled disk-shaped part, the sequence of machining technology of the aluminum alloy thin-walled disk-shaped part is optimized, and the aging treatment removes residual cutting thermal stress remained in the workpiece during rough machining, so that in the subsequent finishing stage, deformation of the workpiece caused by the residual cutting thermal stress is reduced, a foundation for improving themachining quality and machining accuracy is laid,the calibration process calibrates the shape and size of the outer contour of the workpiece, the finished product machining pass rate of the part is ensured, and the machining accuracy and processing quality are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing technology, in particular to a processing method of a T4 aluminum alloy thin-walled disc-shaped part. Background technique [0002] Thin-walled disc-shaped parts are widely used in various industrial sectors in the national economy. However, when the material of thin-walled disc-shaped parts is aluminum alloy, due to the weak strength and poor rigidity of the aluminum alloy material, it is difficult to process such thin-walled disc-shaped parts. The workpiece is easily deformed when it is a disc-shaped part, which affects the machining accuracy and quality of the part. For a long time, the processing of aluminum alloy thin-walled disc-shaped parts has become an urgent technical problem in the process of mechanical cutting. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a processing method of T4 aluminum a...
