How to ensure high precision size of sheet metal bending
General sheet metal processing accuracy to ensure linear dimensional tolerance in GB/T1804-M, that is, medium grade, general bending master can ensure to 0.2-0.3mm within the tolerance range, with CNC bending. The bending coefficient in your factory must be the coefficient value that comes out of the actual operation, rather than the theoretical coefficient. The different V slots used and the different cutting tools are influential to the bending size, and even the thickness of the materials sent by different plate… Ler mais "How to ensure high precision size of sheet metal bending
