A lot of times, I will come across some aluminum alloy CNC machining. If the hardness of the 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, it is necessary to prevent deformation before mold opening and rough machining. The contour structure is roughly opened, and the front and back sides are flattened so that they are vertical, and the front and back sides of the light knife are made by machine. If the sidewalls of the workpiece are thin, it must be thermohardened before placing the machine. It is also possible to leave a thickness depending on the structure of the workpiece. Then straighten the perpendicularity of the parallelism of the workpiece and brush the entire plane of the workpiece. It is also possible to solve the problem of workpiece deformation.
If it is a relatively small workpiece, then 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 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 be deformed too much.
For some thinner workpieces, it is reasonable to make side fashion clips. It is not possible to clamp the workpiece without force with bow clamps. It is best to flatten the workpiece with a right-angled iron and then clamp the workpiece to a flat place with a right-angled iron with a bow clamp. In many cases, the deformation is caused by unreasonable clamping.
