CNC Punching Inconel 718 from VT machining delivers precision Inconel 718 parts made to your exact drawing. CNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns, with parameters tuned to Inconel 718, which is high-temperature strength and oxidation resistance.
CNC Punching Capability for Inconel 718
- High-temperature strength
- Oxidation resistant
- Tolerance to ±0.01 mm
- Aerospace-grade
Machining Inconel 718 with CNC Punching
When punching Inconel 718, machinability is very difficult; rigid setups, carbide/ceramic tooling, low speeds. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for Inconel 718 mean predictable cycle times and stable, repeatable results.
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.
CNC Punching Tolerances & Surface Finish
Punched Inconel 718 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.
Why Inconel 718?
Customers select Inconel 718 for CNC Punching because it is high-temperature strength and oxidation resistance. We handle grade verification and any required heat treatment or finishing.
Design Tips for CNC Punching Inconel 718
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 Inconel 718. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Most Inconel 718 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.
Applications of CNC Punching Inconel 718
Inconel 718 parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What surface finish is achievable on Inconel 718 with CNC Punching?
Surface finish on Inconel 718 is controlled to your specification; we confirm the achievable Ra against your callout.
What tolerances can you hold for CNC Punching Inconel 718?
Achievable tolerances for Inconel 718 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.
How clean are the edges produced by CNC Punching on Inconel 718?
Punched Inconel 718 edges are clean when punch/die clearance is correct; we set clearance to the gauge and can add deburring if specified.
What is the typical lead time and minimum order for CNC Punching Inconel 718?
CNC Punching prototypes for Inconel 718 can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
