Why CNC Punch?

There are different machine operations that can be used to perforate materials and CNC punching is one of them. At Hendrick, low volume jobs or the need for unique patterns are ideal for this method. With our state-of-the-art equipment, turn-around is fast and economical. 

There’s a lot more we can do with our punch equipment than just perforating.  Need a dimple or notch? How about counter sinks or bores?  Embossing or extrusions? Hendrick’s CNC Punch equipment can perform a wide range of fabrication operations, whether it’s a value add to perforated material or part of manufacturing process for a formed product. 

Through the use of CAD/CAM combined with CNC technology, accuracy and efficiency are unparalleled.  It offers extremely high accuracy—at Hendrick, down to 0.004”. Since it can perform multiple operations at once, versatility and productivity is increased. 

With our extensive expertise, advanced equipment and full customization capabilities, Hendrick is the ideal resource for this and many other fabrication services. Our experience includes, stainless steel punching, aluminum punching, and steel punching among others. We can customize our services to meet your needs no matter what they are.

How the Punching Process Works

This procedure involves placing sheet metal between a punch and a die, which are typically made of hardened steel or tungsten carbide. As the machine presses down on the metal, it shears through to make a hole of a specific shape and size. This technique may also be used to create embossed patterns or dimples in applications where the materials are not completely punctured.
