Punch Press Stamping

With our multiple single station, turret station, or single point gap series presses, Classic Sheet Metal is configured to meet your production requirements from short run to long run production volumes.
 

Unlike single station turret presses “nibbling” away your desired part one tool at a time, these Gap Presses are capable of producing a completed part with as little as one hit. Using die sets referred to as “hard tooling” to minimize the punching process, Gap presses allow a completed part or series of parts to be reproduced quickly and efficiently.

Classic Sheet Metal’s new oiling system automatically injects vanishing oil onto the cutting surface to extend die life as well as decrease the amount of burring produced by punching process. This oiling system greatly reduces the need for secondary operations to remove these burrs, such as tumbling and timesaving.

Punch Press Stamping Defined

A punch press is commonly mechanically operated but some simple ones are manpowered. A punch press often consists of these parts: frame, motor, a ram that holds the punch, die posts, bed, and bolster plate that holds the die. A punch is often made of hardened steel or carbides. The punch press forces the punch into a work piece to pierce a hole that has a diameter equivalent to the punch.  A die is located on the opposite side of the work piece and supports the edges of the hole created to keep it from deforming during the punch. There is a small amount of clearance between the punch's diameter and the die's. This clearance depends on the work piece material and various tolerances.
