Precision Machining for Difficult Alloys

Sinker EDM for Inconel Alloys

AXALLOY Precision specializes in Sinker EDM for Inconel alloys and other difficult-to-machine materials. We deliver precision, high-quality components that meet the strict requirements of aerospace, medical, semiconductor, energy, and precision industrial applications.

Why Sinker EDM for Inconel?

Inconel and other nickel-based superalloys present significant challenges for conventional machining. Sinker EDM overcomes these obstacles with unmatched precision and versatility.

  • Complex internal geometries

    Deep cavities, ribs, narrow slots, blind features, and sharp internal corners with minimum radius R0.05 mm.

  • Tolerances down to ±0.005 mm

    Positioning accuracy ±0.005 mm and repeatability ±0.003 mm.

  • Surface finish as low as Ra 0.4 μm

    Ideal for demanding sealing surfaces and precision interfaces.

  • Suitable materials

    Inconel 718, Inconel 625, Hastelloy C-276, Titanium Grade 5, stainless steels, tool steels, and other hard alloys that are difficult or impossible to machine with traditional milling or turning.

  • Large workpiece capacity

    Up to 500 × 350 × 300 mm and 800 kg.
