Difficult-Alloy Precision CNC Machining
Small Precision Turned Parts for Difficult Alloys
We produce small precision turned parts with tight, stable tolerances in nickel-based superalloys, titanium, PH stainless steels, duplex grades and cobalt alloys. From prototypes to repeat production, we help engineering, procurement and quality teams reduce risk, validate design intent earlier and receive the documentation needed for regulated markets.
AXALLOY is based in Shenzhen and works with customers in aerospace, medical devices, semiconductor equipment, energy, oil and gas, marine, robotics and advanced industrial equipment.
What you get when you work with us
Reliable dimensional control on small, critical features
Repeatable tolerances down to ±0.005 mm and roundness down to 0.005 mm help your assemblies fit and seal the first time.
Stable processes for difficult-to-machine alloys
We tune cutting parameters, tooling, coolant and fixturing for Inconel, Hastelloy, titanium and PH stainless steels so you don't lose time to trial-and-error at another shop.
Faster path to design validation and release
Prototype lead times of 5–10 business days let you test functional interfaces earlier, lock tolerances with evidence and keep program milestones on track.
Documented quality for regulated markets
Material certification, first article inspection and full dimensional reports reduce audit friction and simplify incoming inspection.
Clear communication and controlled change
You get DFM feedback up front, a defined production route and transparent updates so there are no surprises when parts arrive.

What this means for you
Incoming inspection is faster, audit evidence is ready, and nonconformances are prevented—not explained after the fact.
Lead times and how speed helps your program
- Prototype lead time: 5–10 business days
- Standard lead time: 10–20 business days
- Expedited service: available on request
- MOQ: 1 part, volumes from 1 to 10,000+ pieces
Faster prototypes let you validate critical fits and threads earlier, freeze tolerances with measurement evidence, and align supplier capacity with your ramp plan. Short, reliable lead times reduce buffer stock and help procurement hit delivery targets without inflating inventory.
How we keep small turned parts consistent
Material control
Lot-traceable bar stock, verified hardness and condition to ensure predictable cutting performance.
Tooling and setup
Guide bushing and collet selection matched to diameter; tool stick-out minimized to control chatter on small diameters.
Cutting data by alloy family
Conservative entry parameters for nickel alloys; high-pressure coolant and chip control to prevent built-up edge.
In-process inspection
SPC on critical dimensions, thread gauges at defined intervals, and go/no-go controls for key fits.
Deburr and clean
Controlled deburring to protect edges and threads; cleaning and passivation where required by spec.
Documentation discipline
FAI on first lot, recorded process parameters and inspection plans support repeatability.
DFM tips for small precision turned parts
Send us your drawing early—we'll review for manufacturability and propose practical changes that protect function and schedule.
Tolerances
Assign tight tolerances only to functional features; we can hold ±0.005 mm where needed, but relaxing non-critical dimensions improves repeatability and cost.
Runout and concentricity
Call out datum structure; specify runout at the assembly-critical diameter rather than across multiple features.
Threads
Include thread reliefs where possible; specify class/fit and surface finish on sealing threads; note any thread locking compound needs.
Thin walls
For walls under 0.5 mm, flag as critical; we may suggest minor geometry changes or a different route (e.g., grind or EDM) for stability.
Cross holes
Provide exact positional requirements and deburr criteria; we can machine and deburr cross ports, but access and edge conditions should be defined.
Surface finishes
State Ra and inspection location; a default Ra 1.6 μm is suitable for most features, while sealing faces may need Ra 0.4–0.8 μm or grinding.
