Many times, I will encounter some aluminum alloys. If the hardness of aluminum alloy is low, it is easy to deform after processing. If some large aluminum alloy shell parts are encountered, in order to prevent deformation, deformation shall be prevented before mold opening and rough machining. Roughly open the contour structure, then flatten the front and back faces to make them vertical, and then use the machine to make the front and back faces of the light knife. If the side wall of the workpiece is very thin, it must be heat hardened before placing the machine. The thickness can also be reserved according to the structure of the workpiece. Then straighten the perpendicularity of the workpiece parallelism and brush the entire plane of the workpiece. It can also solve the problem of workpiece deformation.
If it is a 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 problem of deformation, or you can first flatten the wool, and then use the surface as the bottom. Then use the other side as the front side, so that the workpiece can be vertical and the workpiece will not deform too much.
For some thinner workpieces, it is reasonable to make side fashion clips. It is not possible to clamp the workpiece without force using the bow clamp. It is better to flatten the workpiece with a right angle iron, and then clamp the workpiece to the flat place of the right angle iron with an arch clamp. In many cases, the deformation is caused by improper clamping,
