Mate Precision Tooling offers modified standard and custom press brake tools. Bending variations may require modifying the angle of a standard punch or die a few degrees. This is easily accomplished because the induction hardening depth is 3 mm to 4 mm. This allows material removal to modify an angle or change a radius without jeopardizing the structural integrity of the tool. Other frequent tool modifications include cutting a window or relief pocket to provide clearance so that a formed part does not collide with the punch during the forming process.
