Many times, I will come across some aluminum alloys. If the hardness of aluminum alloy is low, it will be easily deformed after processing. If some large aluminum alloy shell parts are encountered, in order to prevent deformation, deformation must be prevented before mold opening and rough machining. Roughly open the outline structure, then flatten the front and back sides to make them vertical, and then use a machine to make the front and back sides of the light knife. If the side walls of the workpiece are very thin, they must be heat-hardened before being placed on the machine. Thickness can also be left according to the structure of the workpiece. Then straighten the parallelism and verticality of the workpiece and brush the entire plane of the workpiece, which can also solve the problem of workpiece deformation.

If it is a relatively small workpiece, the product plane should be flush with the workbench, and there should be no gap when making the reverse side. Then you can use the reverse side to solve the deformation problem, or you can flatten the wool first and then use the side as the bottom surface. Then use the other side to make the front side, so that the workpiece can be vertical and the workpiece will not deform too much.

For some thin workpieces, it is reasonable to make side fashion clips. The workpiece cannot be clamped without force using a bow clamp. It is best to use a right-angle iron to flatten the workpiece, and then use a bow clamp to clamp the workpiece to the flat place of the right-angle iron. In many cases, deformation is caused by improper clamping.
