CNC PunchingHoles and forms at speed.
High-speed CNC turret punching for holes, louvers, and complex formed features in sheet metal, with consistent accuracy across production volumes.
WHAT IS IT
CNC turret punching drives a 30-ton ram through sheet using a library of tools: holes, slots, louvers, and knockouts at production tempo.
For the right flat pattern, punching beats laser on cost and adds formed features laser cannot make in the same cycle.
When to punch
Choose punching when the drawing is rich in repeated holes or needs louvers, embosses, or countersinks without a second operation.
One-off organic contours still belong on laser. We will say so at quote time.
How it works
Program, punch, and clear the blank
1 · PROGRAM
Program the turret
Your flat pattern is mapped to the tooling library. Tool hits and sheet indexes are sequenced for a single automated cycle.

Punch vs laser
Match the process to the pattern
CNC punching
- Most economical for repeated holes at volume
- Louvers, embosses, countersinks in-cycle
- Fast cycles on production sheets
- Standard tooling with no die charges for common features
Laser cutting
- Irregular profiles and one-off geometry
- No dependence on turret tool shapes
- Cleaner option for sparse hole patterns
- Often paired with punch on hybrid nests
Send the flat pattern. If punch wins on cost, we will quote it that way.

- Cost-effective
Hot Rolled Pickled & Oiled
HR P&O plate and sheet with mill scale removed and a light oil coat, ready for cutting, forming, and welding.
- Scale-free
- Weldable
- Production-ready
Stainless Steel 304
304 stainless in 2B and #4 finishes for corrosion resistance and clean cosmetic surfaces.
- 2B finish
- #4 finish
- Corrosion resistant
Aluminum & Coated Steels
Aluminum for lightweight parts, plus galvanized and other coated steels for weather and washdown environments.
- Lightweight aluminum
- Coated steels
- Corrosion protected
