CNC Punching Steel from VT machining delivers precision Steel parts produced to your exact drawing. CNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns, and we tune every parameter to the behaviour of Steel, which is strong, economical, widely available carbon/alloy grades.
CNC Punching Capability for Steel
- Sheet thickness 0.5–6 mm
- Hole position repeatability ±0.10 mm
- Punch/die clearance set per material
- Louver, emboss and tap-extrude tooling
How CNC Punching Steel Works
A CNC turret presses hardened punches through the Steel 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.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.
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.
Secondary Operations & Finishing
Most Steel 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.
Working with Steel
Steel is strong, economical, widely available carbon/alloy grades. We translate those properties into a process plan: the right tooling, speeds, feeds and fixturing for the alloy.
Where the grade, temper or heat-treat condition matters to performance, we confirm it with you and can supply material certificates. Material is procured to recognised standards for consistent, repeatable results.
CNC Punching Tolerances & Surface Finish
Punched Steel holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Design Tips for CNC Punching Steel
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 Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Punching Steel
Steel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
