CNC Punching Brass from VT machining delivers precision Brass 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 Brass, which is free-machining, good conductivity, attractive finish.
CNC Punching Capability for Brass
- 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 Brass Works
A CNC turret presses hardened punches through the Brass 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.
Programming is driven directly by your 3D model or print. Work-holding, tool selection and the cutting strategy are planned around the critical features and the material before the first chip is cut. First-off inspection confirms the process is centred before production continues.
CNC Punching Tolerances & Surface Finish
Punched Brass holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
Working with Brass
As a material, Brass is free-machining, good conductivity, attractive finish. Our setup reflects the alloy's machinability so the finished part is accurate and free of avoidable defects.
We verify the exact grade and condition before machining, and traceable mill certs are available on request. We can work to your nominated material source or specification when required.
Secondary Operations & Finishing
Finished Brass parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
Design Tips for CNC Punching Brass
We are happy to suggest design tweaks that improve manufacturability. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched Brass. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Punching Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every Brass part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Applications of CNC Punching Brass

Request a QuoteFrequently Asked Questions
How clean are the edges produced by CNC Punching on Brass?
Punched Brass edges are clean when punch/die clearance is correct; we set clearance to the gauge and can add deburring if specified.
What material thickness or size range suits CNC Punching Brass?
Punching suits Brass sheet roughly 0.5–6 mm thick, with clearance matched to the gauge.
Does CNC Punching Brass require dedicated tooling?
Punching uses programmable turret tooling; standard tools cover most patterns, with special tools added for unique forms.
What surface finish is achievable on Brass with CNC Punching?
Surface finish on Brass is controlled to your specification; we confirm the achievable Ra against your callout.
What is CNC Punching Brass and how is it done?
CNC Punching Brass refers to cNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns. Applied to Brass — free-machining, good conductivity, attractive finish — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
