CNC PUNCHING
Explore the CNC Punching Services Haake Manufacturing uses to produce many different types of parts for your most demanding tasks.
CNC PUNCHING OVERVIEW
There are a lot of ways to shape sheet metal, and none of them are necessarily wrong. But there are different methods that work best for different kinds of materials, tolerances, and the functions of the parts you’ll be producing.
CNC Punching works well as a high-efficiency solution for thinner materials and parts that require formed features.
Benefits of CNC PUNCHING
CNC punching delivers high-speed production for thin sheet metal, cost efficiency at higher volumes, and the ability to form features like louvers, extrusions, and countersinks in a single operation.
Here are a few of the biggest things to consider as you’re choosing a metal cutting process and why CNC punching is becoming a go-to choice for manufacturers.
When to Consider CNC PUNCHING
Material Type
Well-suited for mild steel, stainless, aluminum, and galvanized materials; process parameters adjust automatically by material.
Material Thickness
Highly efficient on thin to medium gauges; performance and speed decrease as thickness increases, where alternative methods may be evaluated.
Tolerance Requirements
Capable of tight, repeatable tolerances with minimal variation part-to-part.
Edge Quality
Produces smooth edges with minimal burrs; nitrogen cutting eliminates oxidation, improving weld and finish quality.
Geometry Complexity
Excels at complex profiles and fine features with no tooling constraints.
Production Volume
Minimal setup makes it ideal for prototypes and low-to-mid volumes; remains viable for production depending on part complexity.
Secondary Operations
Clean edges reduce deburring; consistent cuts improve downstream welding, bending, and coating processes.
Total Cost
Reduced setup, fewer secondary steps, and faster turnaround often lower total project cost.
HAAKE’S APPROACH TO CNC PUNCHING
Haake Manufacturing’s CNC punching technology permits complex, three-dimensional processing with the goal of complete processing on one machine. The punching head on each machine has full, 360-degree rotation.
Custom-shaped Materials & Tolerances to Fit What You Need
Haake can work with a variety of materials during the CNC punching process. We’ve also tested a range of thicknesses, and have found 0.1” to 0.125” to be the ideal top range we punch for.
Reduce Lead Times WITH Secondary Machining
We offer these secondary processes as part of our CNC punching, which directly improves efficiency, accuracy, and total cost.

combination solutions for Your Toughest Jobs
Sometimes, you have a challenging job that would benefit from two metal stamping processes. We’re a shop that embraces these projects, and we are the only job shop in the St. Louis region that has punch and laser processing on the same machine.
Our combination machine has all the benefits of both punching and laser processing. This combination processing allows us to produce parts quickly without the added time and cost associated with moving the parts between separate machines.
Advanced Laser Technology for Uncompromising Quality
We’ve chosen Trumpf’s equipment for laser cutting because they have been developing laser technology since 1923.
They have the learnings, technology, and resources to optimize upstream and downstream laser cutting processes, which means you get the most innovative equipment with the best outcomes.
