Nickel-chromium superalloy milled on 5-axis centers for aerospace and medical parts. We hold ±0.005 mm, control tool wear, and inspect every part before shipment.
Four failure modes we see on incoming RFQs and rework tickets.
This alloy work-hardens fast. Feeds and speeds copied from 316 stainless burn the insert in minutes, then the operator slows the program and the cycle time doubles. A 200-piece run turns into three weeks of insert changes and scrapped shoulders.
Nickel alloys conduct heat poorly, so the edge takes almost all of it. Without high-pressure coolant aimed at the flank, the part grows, the finish smears, and a bore that measured Ø25.000 mm at 08:00 measures Ø25.040 mm after lunch.
Aerospace seals and medical housings often have 1.5 mm walls. Rough and finish in one setup with heavy radial engagement, and the part springs back when the vise opens. It passes on the machine and fails on the CMM.
For parts that see thermal cycling, the wrong pass direction leaves a surface that cracks earlier in service. The drawing says Ra 1.6 μm. It does not say which way the cutter should travel, and that gap causes field failures.
Two things decide the outcome: how the tool enters the material, and how the heat leaves it.
We do not climb into Inconel 600 with a full-width pass. The toolpath uses trochoidal and dynamic milling: shallow radial engagement, deep axial cuts, constant chip load. The edge stays in the cut for a short arc, so heat leaves with the chip instead of soaking into the workpiece.
Roughing runs on 5-axis centers with through-spindle coolant. On the 16 simultaneous 5-axis machines, we can orient the tool to a compound angle and cut a contoured flange in one continuous pass instead of three setups. Fewer setups means fewer chances for a locating error.
Inconel 600 moves with temperature. A bore cut at 40 °C and measured at 20 °C will not read the same number. We rough, let the part stabilize, then finish with light passes and measure on the machine before the vise opens.
Critical features go to the CMM. We record raw material certificates, in-process dimensions and final inspection results, and send the reports with the shipment when the drawing calls for them. Tolerance is ±0.005 mm where the geometry allows it, with Ra 0.8–1.6 μm on sealing faces.
Compare the service conditions before you commit to a nickel alloy.
| Condition | Inconel 600 (N06600) | Better alternative |
|---|---|---|
| Continuous service above 700 °C | Good creep resistance, stays austenitic | Inconel 625 for higher strength |
| Chloride stress corrosion | Resists it well | Stay with N06600 |
| Seawater immersion | Pitting possible | Inconel 625 or 625 cladding |
| Tight tolerance on thin walls | Machinable with light passes | Consider 17-4PH if corrosion allows |
| Cost-driven bracket, room temperature | Overkill for the duty | 304 or 316L stainless |
| High-cycle thermal fatigue | Needs controlled surface finish | Specify pass direction on the drawing |
One shop for the milling, turning and finishing steps.
16 simultaneous 5-axis centers for contoured flanges, impeller-like geometry and compound-angle holes. One setup replaces three.
12 four-axis mills and 27 three-axis machines for prismatic housings, manifolds and plate work with drilled patterns.
16 mill-turn centers cut a turned body and a milled feature without a second chucking, which matters on coaxial bores.
Single pieces for fit checks and thermal test coupons before you commit to a production run.
Bead blasting, tumbling, brushing and polishing. Laser marking down to 1.5 mm character height for traceability.
Deburred edges, chamfered entries and cleaned threads so the part goes straight to the bench.
Numbers you can check against your part size.

Six things that decide whether your program ships on time.
Three wholly-owned plants and 150 technicians working out of 7,600 m² in Dongguan, plus a Singapore factory for regional delivery.
Held on nickel parts where the geometry allows, backed by 100% inspection before shipment and reports on request.
Send a STEP file and a drawing. We come back with a price and a manufacturability note, not just a number.
Raw material check, in-process monitoring and final inspection on every order, from one piece upward.
16 five-axis, 12 four-axis, 27 three-axis and 16 mill-turn centers. We pick the machine that fits the part.
ISO 9001:2015, IATF 16949:2016, ISO 13485:2016 and ISO 27001:2022. Medical and automotive programs are covered.
Thin-wall rings and flanges that must stay round after clamping.
Small bodies with coaxial bores and a clean, burr-free exterior.
Parts that hold shape through repeated thermal cycling.
Valve bodies and fittings exposed to chlorides and hot process fluid.
The alloy keeps its strength at temperature and work-hardens quickly under the cutter. Heat does not escape through the chip the way it does in stainless, so the edge runs hotter and wears faster.
The practical result is lower cutting speeds, smaller radial engagement and a rigid setup. Push it like stainless and you lose the insert and the dimension.
Yes, on features where the geometry and wall thickness allow it. Thin walls and long unsupported bores are harder, and we will tell you which dimensions are realistic before we quote.
Every part is inspected before shipment, with raw material checks, in-process monitoring and a final inspection. Reports go out on request.
Ra 0.8–1.6 μm covers most sealing faces and bearing fits. If you need a finer finish, Ra 0.2–0.8 μm is available with additional finishing passes.
Specifying a tighter finish than the function needs adds cycle time, so match it to the sealing or wear requirement.
Yes. There is no minimum order quantity, from a single prototype to runs of 10,000+ parts.
Prototypes often run on the same machines as production, so the process you qualify is the process you get later.
We rough with material left on, let the part stabilize, then take light finishing passes with low radial engagement. Support fixtures and adaptive toolpaths reduce the load that causes the spring-back.
If a wall is very thin, we will say so in the DFM note and suggest a change to the geometry or the setup.
We hold ISO 9001:2015, IATF 16949:2016, ISO 13485:2016 and ISO 27001:2022.
ISO 13485 covers the medical device side. ISO 27001 covers how we handle your drawings and CAD files, and we sign an NDA on request.
