CNC Punching Services: Fast Sheet-Metal Features
CNC punching drives a turret of shaped tools through sheet metal to cut holes, slots, and forms at high speed. For enclosures, brackets, and panels in volume, it’s faster and cheaper than laser for many patterns. This guide covers how it works, when to choose it, the materials, and how to spec your job.
How CNC Punching Works
A turret punch press indexes the sheet under a rotating tool set and stamps features in quick succession. We often bend the punched blank right after, and we machine any critical features on a CNC mill.
CNC Punching vs. Laser Cutting
Punching wins for many identical holes and forms at volume; laser cutting wins for complex contours and prototypes. Choose by pattern and quantity.
Materials We Punch
- Steel and stainless sheet—enclosures and brackets.
- Aluminum—panels and frames.
- Brass and copper—electrical parts.
Industries That Rely on CNC Punching
Electrical enclosures, appliance panels, and bracket production all use punching for economical volume.
How to Spec Your CNC Punching Job
- State material and thickness.
- Provide the hole/slot pattern (DXF or drawing).
- Define tolerances on features and flat.
- Note any forms (louvers, ribs, tabs).
- Flag secondary ops (bend, tap, finish).
- Share volume for tooling choice.
FAQ
What thickness can you punch?
Up to several mm in steel; more with the right tool.
Is it as clean as laser?
Slight dimple at hit points; fine for most parts.
Can you do forms?
Yes—louvers, ribs, and tabs in the same press.
