CNC Punching

A die, located on the opposite side of the work piece, supports the material around the perimeter of the hole, so as to help localize the shearing forces for a cleaner edge. CNC Punching is the most affordable method of creating multiple holes in sheet metal, especially in medium to high production volumes.

Punching Characteristics:

• It is a fast method, which saves precious manufacturing time.
• Cost effective solution when punching square holes in sheet metal.
• Metal Punching creates multiple various type of holes.
• Punches and dies are commonly made from hardened steel.

The punch itself can vary in size and shape. Usually, the punch and die have similar dimensions however purposed to create a so-called extruded hole to ensure quality and precise punching.
