Angle steel punching machine The workpiece shall be fully positioned in the fixture, and the base fluid of the workpiece shall be strictly positioned relative to the machine tool origin, so as to meet the requirements of relative movement between the workpiece and the tool in the machine tool coordinate system. At the same time, the fixture should also be fully positioned on the machine tool, and each positioning surface on the fixture should have accurate coordinate dimensions relative to the machine tool origin to meet the requirements of positioning and installation in NC processing. Due to angle steel Punching machine It has the characteristics of continuous multi profile automatic processing, so the requirements of the diagonal steel punching machine fixture are higher in precision and rigidity than the general machine tool fixture, which can reduce the positioning error, clamping error and deformation error in rough machining of the workpiece in the fixture.
