WIRE EDM
Precision cutting for intricate geometry and tool-critical detail.
When geometries are too tight for conventional machining, Gromax delivers.
Our Wire EDM services ensure ultra-fine internal details and profile accuracies remain perfectly true to print.
Precision Wire EDM Cutting
Wire EDM cutting for conductive materials where intricate profiles, narrow slots, and fine internal features need tighter control than conventional machining can typically provide.
Improves feature accuracy, reduces geometry compromise, and helps critical details stay true to print.
Tight Internal Corners & Fine Profiles
Cutting processes built for parts and tooling details where cutter-radius limitations would otherwise affect fit or function.
Delivers closer conformance to print intent for features that can’t tolerate rounded internal geometry.
Tooling Components & Die Details
Wire EDM support for punches, die sections, inserts, wear components, and other tooling-critical details.
Helps protect tool accuracy, speeds repairs or modifications, and supports more stable production performance.
Hard Material Capability
Wire EDM processes suitable for hardened conductive materials and geometry that would be difficult or distortion-prone with conventional cutting methods.
Improves control on difficult materials while reducing the risk of feature distortion or process compromise.
Prototype & Short-Run Precision Parts
Support for prototype parts, repair details, and limited-quantity components where precision geometry matters more than production scale.
Gives engineering and production teams a practical path for validating tight-feature parts before broader process decisions are locked.
Tool Repair & ECN-Driven Modifications
Wire EDM used for tooling repair, engineering changes, and rework of transferred or existing components.
Shortens turnaround on change-driven or recovery work while protecting alignment to current print requirements.
Inspection Aligned to Critical Features
Feature validation built around the geometry that affects fit, function, clearance, alignment, or tooling performance.
Improves confidence that the dimensions being checked are the ones that actually matter in use.
Quality Deliverables & Compliance
Inspection reports, SPC, FAI/FAIR, and related documentation available as required; ISO 9001:2015 and ITAR-supported where applicable.
Supports approvals, traceability, and documentation needs for regulated or high-spec programs.
frequently asked
questions
What is Wire EDM best used for?
Wire EDM is best suited for conductive materials and geometry that requires tight internal detail, narrow slots, fine profiles, or tool-critical accuracy that conventional machining may struggle to hold.
How is Wire EDM different from conventional CNC machining?
CNC machining removes material with rotating tools, which can limit internal radii and create geometry compromises on tight features. Wire EDM uses a precision wire-cutting process that’s better suited for fine profiles and sharp internal detail in conductive materials
Is Wire EDM only used for tooling?
No. It’s commonly used for punches, die details, and repair components, but it can also support prototype parts, short-run precision components, and feature-specific geometry where print accuracy matters most.
Can you support repair work or engineering changes on existing tools?
Yes. Wire EDM is a strong fit for repair, rework, and ECN-driven modifications where existing tooling or components need precise feature updates.
What materials can be processed with Wire EDM?
Wire EDM is used on electrically conductive materials, including hardened tool steels and other conductive alloys where precision geometry is required.
What quality documentation is available for Wire EDM work?
When required, we can provide inspection reports, SPC, FAI/FAIR, and related documentation to support approvals and traceability.
