AXALLOY Precision
Precision EDM Components
AXALLOY Precision provides Wire EDM and Sinker EDM solutions for complex, high-value components in difficult-to-machine alloys. Based in Shenzhen and serving international engineering, procurement and quality teams, we support prototype development through controlled, low-volume and repeat production.
Our EDM services integrate with multi-axis milling, turning, precision grinding and comprehensive inspection to deliver dimensionally precise, burr-free components with reliable documentation.
What We Deliver
- Tight-tolerance profiles, slots, dies and sharp internal corners not achievable by conventional cutting tools
- Stable machining of nickel superalloys, titanium, precipitation-hardening stainless steels, duplex and cobalt alloys
- Proven process control from DFM and fixture planning to inspection strategy and documentation
- Prototype to production support with dependable communication and traceability
When EDM Is the Right Choice
- Sharp internal corners and very small internal radii
- Extremely fine slots, thin ribs and narrow profiles
- Hard, tough or heat-resistant alloys (Inconel, Hastelloy, titanium, PH stainless)
- Delicate geometries where cutting forces would distort thin walls
- Burr-free edges and minimal distortion requirements

Design for EDM (DFM) Guidelines
Start Holes for Wire EDM
Provide a start hole where possible. Typical practical range Ø0.2–2.0 mm; we can prepare start holes via drilling or pre-machining when not defined on drawing.
Minimum Kerf / Slot Width
≥0.15 mm (wire diameter and strategy dependent).
Corner Radii
Wire EDM: internal corners can be extremely sharp relative to tool-machined features; specify minimum radii if intentional. Sinker EDM: minimum internal radius down to R0.05 mm with appropriate electrode strategy.
Tapers & Draft
Wire EDM supports up to ±30° taper; call out taper direction and datum references.
Wall Thickness
For unsupported walls, ≥0.5 mm is recommended; thinner features may be feasible with process controls—flag as critical.
Tolerance Stacking
Identify critical datums and GD&T to align machining, EDM and inspection strategies.
Surface Integrity
EDM leaves a thin recast layer; specify if post-EDM polishing, stoning or light grind is required for fatigue-critical or sealing surfaces.
Fixturing & Access
Allow clamping allowances and flush paths; avoid obstructed cavities that limit dielectric flow.
Threads & Forms
For extremely small or interrupted internal forms, consider pre-machining followed by EDM finishing; we also support thread milling/tapping for hybrid processes.
Documentation
Annotate critical features, inspection points and surface requirements on the 2D drawing to reduce ambiguity.

Frequently Asked Questions
Can you EDM hardened or heat-treated parts?
Yes. EDM is well-suited to hardened and high-temperature alloys. If recast removal is required, we can follow with fine grinding or polishing.
How small can my slot or internal corner be?
Wire EDM kerf is typically ≥0.15 mm; for internal radii, Sinker EDM can achieve down to R0.05 mm with the right electrode and strategy.
What surface finish can I expect?
Wire EDM down to Ra 0.8 μm (multi-pass skim); Sinker EDM down to Ra 0.4 μm. Precision grinding to Ra 0.2 μm is available when specified.
Do you provide inspection and traceability?
Yes. We offer MTRs, CoC, FAI, ballooned drawings, full dimensional reports and special-process records with calibrated equipment in a controlled inspection environment.
Which industries and regions do you serve?
We regularly support aerospace, medical, semiconductor and precision industrial projects across North America, Europe, the UK, Australia, New Zealand and advanced Asian markets.
