Explore VT machining's CNC Punching capability. CNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns.
CNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns. Because the same engineers handle quoting, programming and inspection, nothing is lost between your drawing and the finished part.

FREQUENTLY ASKED QUESTIONSWhat can CNC turret punching produce?
Repeatable hole grids, slots and form features in sheet metal using programmable standard round, square, obround or custom tooling — fast and economical for perforated patterns and enclosure blanks.
CNC Punching shears holes and formed features out of sheet metal using programmable turret tooling. It is exceptionally fast and repeatable for hole patterns, louvres, embosses and tap extrusions, and remains the most economical route for higher-volume sheet parts.
VT machining runs CNC Punching in-house, so scheduling, quality and revisions stay under one roof. CNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns — and the parameters are set from your material and geometry, not a default recipe. Send a CAD model or a 2D print and we will confirm feasibility, tolerances and lead time before you commit.
How CNC Punching Works at VT machining
A CNC turret presses hardened punches through the metal sheet into matching dies. Punch-to-die clearance is set as a percentage of thickness so the cut edge stays clean and burr is minimal.
Every job begins from your CAD model or 2D drawing. Fixturing and tool paths are planned so the most critical dimensions are produced in the most rigid, repeatable setup. Critical dimensions are checked on the first part and monitored through the run.

Send your drawing
CAD model, PDF print — or a drawing you build free on this page. We reply with feasibility, price and lead time.
2
Tooling & nest layout
Punch-to-die clearance is set from the gauge; tools are nested for minimum sheet waste.

CNC Punching run
First article is verified against the print before the balance of the batch is released.

Inspection & dispatch
In-process checks plus final inspection, with CMM reports, mill certs and FAIR on request.
CNC Punching Tolerances & Surface Finish
Punched metal holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.

Figures are typical in-house capability. Send your drawing and we will confirm what is achievable for your specific part.
CNC Punching by Metal — Choose Your Material
Choose a metal below for grade-level detail, achievable tolerances and typical parts in that material.
Small design adjustments often cut cost and lead time. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched metal. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Most metal parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
CNC Punching Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.

Ordering metal parts is straightforward. Provide the drawing, material, quantity and any certification needs. Our engineers reply — in English — with feasibility, pricing and a realistic lead time, usually within one business day.
Have a drawing ready? Send it with your quantity and material for a quotation, usually within one business day.
Achievable tolerances for CNC Punching depend on the alloy, geometry and feature size. Punching holds hole-position repeatability to around ±0.10 mm. Exact figures are confirmed against your drawing callouts.
What surface finish is achievable on with CNC Punching?
Surface finish on the part is controlled to your specification; we confirm the achievable Ra against your callout.
Can VT machining make custom parts to my drawing?
Yes. CNC Punching is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
Does CNC Punching require dedicated tooling?
Punching uses programmable turret tooling; standard tools cover most patterns, with special tools added for unique forms.
What material thickness or size range suits CNC Punching?
Punching suits the material sheet roughly 0.5–6 mm thick, with clearance matched to the gauge.
