A CNC punch press holds a turret of tools and moves the sheet under them. Each stroke shears a hole, a slot or a formed feature in one hit, and the machine indexes to the next position in a fraction of a second. For a part with hundreds of identical holes, or a run of hundreds of identical parts, that is quicker than tracing every contour with a beam — and the punch can also form louvres, countersinks, extrusions and knock-outs that a laser cannot.
What gets punched
- Perforated panels, ceiling tiles and enclosure sides with regular hole patterns.
- Electrical and HVAC sheet-metal parts — chassis, brackets, panels with knock-outs and louvres.
- Blanks for downstream bending, where the flat outline and every hole are punched in one program.
- Formed features in flat sheet — countersinks, tapped extrusions, embosses and stiffening ribs.
Why punch rather than cut
Punching and laser cutting sit side by side in our workshop and each has its job. A laser wins on one-off parts, intricate contours and thick plate. A punch wins on repetition: a standard hole is one stroke regardless of size, tooling is already in the turret, and formed features come out of the same machine. Sheet-to-sheet punching handles individual sheets; our coil-fed line handles long perforated runs from coil.
Blanking — punching the whole outline of a part in one stroke — is available where a dedicated tool exists or the quantity justifies making one.

From your file to punched parts
- Send the drawing — DXF or DWG preferred. We check every hole and form against the tools in the turret and flag anything that needs a new tool.
- We confirm material, thickness and quantity, and nest the parts across the sheet for best yield.
- Sheets are punched, de-burred where the specification asks for it, and inspected.
- Parts continue to bending, welding, finishing or PVD in the same order — or are packed flat for your line.
