Surface Finishing
For Precision Machined Parts from Difficult Alloys
In 3 seconds you will know exactly what AXALLOY Precision does:
AXALLOY delivers high-precision surface finishing — Ra 0.2 μm mirror finishes, EDM Ra 0.8 μm, EDM Ra 0.4 μm and ground finishes — on nickel-based superalloys, titanium alloys, duplex stainless steels and other difficult-to-machine materials.
We do not just machine. We finish critical interfaces, seals, hydraulic passages and aerospace-critical surfaces to the exact quality your customers demand.
Our Surface Finishing Capabilities
Every process is calibrated specifically for difficult alloys. We match the right finishing method to your material, geometry and functional requirements — then verify it with documented inspection.
| Process | Surface Finish | Typical Ra | Suitable Materials | Best Applications |
|---|---|---|---|---|
| Precision Grinding | Down to 0.2 μm | 0.2 μm | Inconel, Hastelloy, Titanium, 17-4 PH, A286 | Shafts, bearing journals, precision interfaces |
| EDM | Down to 0.8 μm | 0.8 μm | Inconel, Hastelloy, Titanium, Stainless | Mould cavities, die features, narrow slots |
| EDM (Sinker) | Down to 0.4 μm | 0.4 μm | Inconel, Hastelloy, Titanium | Deep cavities, ribs, blind features |
| General Machining | Precision Ra 0.8 μm | 0.8 μm | All listed difficult alloys | Housings, brackets, structural components |
| General Machining | Standard Ra 1.6 μm | 1.6 μm | All listed difficult alloys | Non-critical visible surfaces |
Why AXALLOY Surface Finishing Wins for Real B2B Buyers
Zero compromise on difficult alloys
We have calibrated every process for Inconel 718/625, Hastelloy C-276/C-22, Titanium Grades 5/23, 17-4 PH, MP35N, duplex 2205 and super duplex 2507.
Full traceability & documentation
Every part ships with surface roughness certificate, material traceability and ballooned drawing showing finished surfaces.
Inspection environment
Temperature-controlled CMM room (1.8 + L/300 μm accuracy) guarantees the finish you specify is measured and recorded.
End-to-end control
We review your 2D/3D model, run DFM, define the exact finishing strategy, and deliver first-article inspection report before any production run.
Perfect for Your Projects
- Aerospace & defense critical surfaces (turbine blades, housings, manifolds)
- Medical device implants & instruments (polished titanium & stainless)
- Semiconductor equipment precision interfaces
- Oil & gas / marine high-pressure fittings
- Robotics & automation parts requiring low-friction or corrosion-resistant finishes
We evaluate your surface requirement, geometry, tolerance stack and volume before quoting. No commodity "as-machined" prices — only finished surfaces that meet your exact spec.
