Punch accuracy test method of is what?

precision detection: general standard by static precision press brake machine, 1: the degree of integrity. Take a ruler, Check and width can support pointer table steel ball) Both end and the central position in bed, about to pointer table to determine the direction and the direction of the maximum error before and after. 2: the degree of parallelism. Will slide in the next place, and then put the pointer table on the bed, and moving direction of left and right direction before and after the determination of the maximum error. 3: ( Straight) Point of view. Bed placed square central position, and there he put the pointer table on the slide, slide up and down, the determination of the maximum error. 4: die ( Head) The handle hole and slide the underside of the straight Angle. To die, Head) Handle hole as a benchmark, the pointer table in the slide base rotation, to determine the maximum error of left and right direction before and after the direction. 5: total clearance. With jack in the press center, slide in the dead center, the pointer table in slide underside, jack pressurized pressure make the micro slide up to standards, to determine the maximum error. Various grades and different tonnage have different data standards.
