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.
-
