One of the great advantages of Fine blanking is its ability to produce very fine features. Slots or holes can be placed very near to the edges of the part, or near each other.
Also, fineblanking can produce holes that are much smaller (as compared to material thickness) than can be produced by conventional stamping.
The Tables below show the recommended design guidelines for slots and holes.
