What we do first when we get the sheet metal fabrication drawings?
After get the drawings, depending on the graph and batch choose different way of blanking, including laser, CNC punch, cutting board, mould, and then according to the drawings accordingly.CNC punch press because of the influence of tool aspect, for some alien artifacts and irregular hole processing, the edge will appear larger burr, late for deburring processing, has certain influence on the precision of the workpiece at the same time;Laser machining tool limitations, flat section, and is suitable for machining of abnormity, but for a small workpiece, a longer processing time.Placed beside CNC and laser workbench, conducive to sheet metal is placed on the machine for processing, reduce work load up the plate.Some can use waste material is placed in the designated place, provide material for when the bending test.After the workpiece blanking edges, burrs, contact to make the necessary modification (polishing process), the cutter contact, with a flat file for shaping, for larger burr finishing workpiece with grinding machine, small hole contact with corresponding small file modification, in order to make sure the appearance of beautiful, at the same time, the dressing of shape to bend when positioning as guarantee, to make bending when the workpiece on the bending machine position is consistent, ensuring consistent with batch size.
