Step 2: Milling Process is carried out to workpiece described in step 1 using milling machine, cuts off workpiece surface roughing surplus
In some materials, and reserve allowance for finish appropriate；
Step 3: the workpiece after completion Milling Process in step 2 is subjected to ageing treatment；
Step 4: the workpiece after completion ageing treatment in step 3 is corrected；
Step 5: turnery processing is carried out to the workpiece after completing correction in step 4 using lathe, cuts off excircle of workpiece
Allowance for finish on face and two end faces；
Step 6: Milling Process is carried out to the workpiece after completing turnery processing in step 5 using milling machine, cuts off workpiece
Some materials on two end faces obtain each shape feature on two end faces of workpiece.
Roughing surplus described in step 1 is with a thickness of 1mm.
Carrying out Milling Process described in step 6 further includes obtaining each shape feature on one end face of the workpiece
Later, Milling Process will be continued between the workpiece turning, obtains each shape on another end face of the workpiece
Feature.
Carrying out machining to blank using lathe described in step 1 is by clamping with three-jaw chuck by blank in lathe
It is carried out on main shaft.

Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
The present invention provides a kind of processing method of aluminium alloy thin-walled discoid part of T4, as shown in Figures 1 to 4, including it is following
Step:
Step 1: providing cylindrical blank, carries out machining to blank using lathe, cuts off blank surface major part material
Material, and appropriate roughing surplus is reserved in blank periphery and both ends of the surface, obtain workpiece；It is preferred that roughing surplus is with a thickness of 1mm.
Carrying out machining to blank using lathe is to carry out blank on lathe spindle by clamping with three-jaw chuck.
Step 2: Milling Process is carried out to workpiece in step 1 using milling machine, is cut off in workpiece surface roughing surplus
Some materials, and reserve allowance for finish appropriate；
Step 3: the workpiece after completion Milling Process in step 2 is subjected to ageing treatment；
Step 4: the workpiece after completion ageing treatment in step 3 is corrected；
Step 5: turnery processing is carried out to the workpiece after completing correction in step 4 using lathe, cuts off excircle of workpiece
Allowance for finish on face and two end faces；Turnery processing in step 5, workpiece passed through when Milling Process in step 6 it is auxiliary
Frock clamping is helped to carry out on lathe spindle or milling machine table.
Step 6: Milling Process is carried out to the workpiece after completing turnery processing in step 5 using milling machine, cuts off workpiece
