VT machining specialises in CNC EDM Drilling Hastelloy C22. Because Hastelloy C22 is high-temperature strength and oxidation resistance, and its machinability is very difficult; rigid setups, carbide/ceramic tooling, low speeds, we plan each job around the grade to protect accuracy and surface quality.
CNC EDM Drilling Capability for Hastelloy C22
- High-temperature strength
- Oxidation resistant
- Tolerance to ±0.01 mm
- Aerospace-grade
Machining Hastelloy C22 with CNC EDM Drilling
When EDM machining Hastelloy C22, 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 Hastelloy C22 mean predictable cycle times and stable, repeatable results.
Secondary Operations & Finishing
Most Hastelloy C22 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 EDM Drilling Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Hastelloy C22 part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
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.
Design Tips for CNC EDM Drilling Hastelloy C22
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Hastelloy C22 that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC EDM Drilling 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.
Why Hastelloy C22?
Customers select Hastelloy C22 for CNC EDM Drilling because it is high-temperature strength and oxidation resistance. We handle grade verification and any required heat treatment or finishing.
