Industrial aluminum aluminum profile extrusion mold polishing step
The main results are as follows: (1) According to the design drawings of squeezing molds of aluminum profiles, the working band holes, ultra -precision material models and thin wall pipe models of polishing molds are 00.02mm;
(2) The size and accuracy of the squeezing mold surface surface is 0 0.OSMM. The size accuracy of the super precision material model and the thin -walled pipe mold is 0 0.05mm.
(3) The surface roughness of the mold hole work area is 0.8 0.4, m, and the surface roughness of the diversion slot is 0.8 m.
When sandpaper polishing aluminum mold holes, pay attention to the following points:
(1) Use a soft rod or bamboo stick to polish with sandpaper. When polishing round surfaces or spherical surfaces, using a cork stick can better match the curved curvature of the round surface and spherical surface. Rigid stripes, such as cherry trees, are more suitable for polishing and flat surface. The end of the wooden strip can be repaired, so that it is consistent with the surface shape of the steel sheet, so that the sharp angle of the wooden bar (or bamboo strip) can avoid contact with the surface of the steel sheet and cause deep scratches.
(2) When changing different types of sandpaper, the polishing direction should be changed from 45 to 90 , so as to distinguish the stripe shadow left by the sandpaper before the polishing. Before replacing different types of sandpaper, you must carefully wipe the polished surface with 100%cotton alcohol and other cleaner, because the small sandy gravel on the surface will destroy the entire polishing work. This cleaning process is equally important when the sandpaper polishing to the polishing of diamonds. Before continuing polishing, all particles and kerosene must be cleaned thoroughly.
(3) In order to avoid scratches and burns on the surface of the workpiece, when polishing with#1200 and#1500 sandpaper, it must be specially careful. Therefore, a light load must be loaded and the surface of the workpiece is polished. When polishing in various sandpaper, it should be polished twice in two different directions, and rotate 45 90 between two directions.
