Many times, I will encounter some large aluminum alloys. If the aluminum alloy is low in hardness, it will be easily deformed after processing. If some large aluminum alloys are encountered, in order to prevent it from deforming, it is necessary to prevent deformation before opening and roughing. The outline structure is roughly opened, and then the front and back surfaces are flattened to make it vertical and then the machine is used to make the front and back sides of the light knife. If the side wall of the workpiece is very thin, it must be heat-hardened before the machine is placed. It can also be left in the thickness according to the structure of the workpiece. Then the verticality of the parallelism of the workpiece is straightened and the entire plane of the workpiece is brushed. It is also possible to solve the problem of workpiece deformation.
If it is a relatively small workpiece, then the product plane should be flat with the workbench and there should be no gaps when the reverse side is made. Then the reverse side can be used to solve the problem of deformation, or when the wool is first flattened, the surface is then used 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 be deformed too much. It is reasonable to make the side fashion clips for some thinner workpieces. It is not possible to clamp the workpiece without force with the bow clamp. It is best to flatten the workpiece with a right angle iron and then use a bow clamp to clamp the workpiece to the place where the right angle iron is flat. In many cases, the deformation is caused by the unreasonable clamping, so the reasonable clamping can also prevent deformation.
