Industrial aluminum profile
processing deformation, in addition to the above reasons, in the actual operation, operation method is also very important.
1. The order of cutting should be standardized; Rough machining emphasizes the improvement of machining efficiency and the pursuit of cutting rate per unit time, which can be generally used in reverse milling. That is to cut off the excess material on the surface of industrial aluminum profiles in the fastest speed and the shortest time, and basically form the geometric contour required by finishing. And the emphasis of finishing is high precision and high quality, it is appropriate to use down milling. Because the cutting thickness of the cutter teeth gradually decreases from the maximum to zero when milling, the degree of work hardening is greatly reduced, and the degree of deformation of the parts is reduced at the same time.
2. The thin wall workpiece in the processing due to the clamping deformation, even finishing is difficult to avoid; In order to reduce the deformation of the workpiece to a very small, before finishing is about to reach the final size, the pressing part is loosened, so that the industrial aluminum profile free to return to the original state, and then slightly pressed, to just clamp the workpiece prevail, so that the ideal processing effect can be obtained. In short, the best point of clamping force on the supporting surface, clamping force should act in the direction of the workpiece rigidity is good, under the premise of ensuring that the workpiece is not loose, the smaller the clamping force, the better.
3. When processing industrial aluminum profiles with cavity, try not to let the milling cutter like a drill directly down into the parts when processing cavity, resulting in not enough milling cutter chip space, chip removal is not smooth, resulting in overheating, expansion and parts, knife collapse, broken knife and other adverse phenomena. To use the same size as the milling cutter or one larger drill hole, and then milling cutter; Or, you can use CAM software to produce spiral down the knife program.
