Edges are 100% sheared and bright over the entire thickness. |
Edges are sheared upto one-third of the thickness the rest remaining fractured. |
No deformation occurs in blanking even upto a thickness of 14 mm, i.e. component remains flat. |
Components get dished in blanking, especially with material above 1.5 mm thickness. |
A wall thickness of 60% of the material thickness can be achieved in the blank. |
Not possible. |
Hole diameter of even 60% of the material thickness can be pierced to close tolerances. |
Practically impossible, especially in the case of material thickness of over 1.5 mm. |
Hardness of the sheared edges can be achieved upto 150-200% over the original hardness, due to work hardening. This gives better wear resistance and avoids heat-treatment in some cases. |
Practically impossible. |
Surface finish on sheared edges can be achieved upto 0.8 microns CLA. |
Not possible. |
