What We Hold on Your Parts
Every number below is what we hold on your parts — CMM-verified, with free FAI on your first order.
| Tolerance | ±0.005 mm on critical features |
| Surface finish | Ra 0.4 μm standard, down to Ra 0.1 μm (burr-free) |
| Size range | Prototype to production — send your drawing for a machine-envelope check |
| Materials | Hardened tool steel, stainless 303/304/316, Ti-6Al-4V, carbide, brass |
| Equipment | Wire EDM |
| Batch | Prototype to production (typical: inserts and small batches) |
| Inspection | CMM, FAI report with measured values |
From our historical RFQ data, around 70% of incoming part requests fall within 1–100 pieces. We support both prototype batches and volume production with no minimum-order requirement. Submit your drawing for feasibility evaluation.
Typical Parts We Cut by Wire EDM
Real demand from our RFQ inbox — hardened profiles and internal shapes are among the most frequent EDM requests we receive, mostly for tooling and precision components.
- Die inserts and punches
- Precision slots and internal profiles
- Form profiles in hardened steel and exotic alloys

Frequently Asked Questions
What is wire EDM used for?
Cutting precise profiles, internal shapes and narrow slots in hardened steel, tool steel and exotic alloys that cannot be machined with conventional cutters — die inserts, punches, form profiles and prototype parts with sharp internal corners.
What tolerances can wire EDM hold?
±0.005 mm on critical features, verified on a CMM with a full report. General dimensions run at ±0.05–0.1 mm unless specified.
What surface finish does wire EDM produce?
Ra 0.4 μm as a working standard, down to Ra 0.1 μm with skim passes. The cut is burr-free — no secondary deburring of the profile edges.
Can you EDM after heat treatment?
Yes. Wire EDM is the standard finishing step for hardened tooling — the hardened part is cut to final profile without distortion, which is why it is the default for die and mold work.
Wire EDM or laser cutting — which fits my part?
Wire EDM wins on thick material, tight internal corners and higher precision; laser is faster on thin sheet but leaves a heat-affected zone and larger kerf. For functional profiles in hardened material, EDM is the reliable choice.
Do you provide CMM reports with EDM parts?
Yes. Every batch is inspected on a CMM with a free FAI report on your first order, and we report measured values on critical dimensions.
