Technical Guide
What Is Wire EDM?
Learn how wire EDM uses a travelling wire electrode to cut conductive materials and why drawing access, thickness and tolerance matter.
EDM Feasibility Notes
We review EDM feasibility for the selected material using the drawing geometry, conductive material condition, tolerance, surface finish, quantity and inspection requirements.
Technical Explanation
This guide explains how wire EDM uses a travelling wire electrode to cut conductive materials and why drawing access, material thickness and tolerance requirements matter.
Project question: What Is Wire EDM?
Process Capability Facts
We review EDM process fit from material conductivity, feature access, thickness, geometry, tolerance, surface finish and inspection requirements.
Tolerance, Surface Finish and Geometry Review
Typical tolerance and surface finish depend on material, thickness, feature geometry, flushing, finishing passes and inspection method. Final values must be confirmed from the drawing.
Recast Layer / Surface Integrity Notes
Surface integrity, recast layer, micro-crack risk, post-processing and inspection depend on the material, EDM process, geometry and machine setup.

Frequently Asked Questions
What is wire EDM commonly used for?
Wire EDM is commonly reviewed for through profiles, slots, punches, inserts and conductive precision parts.
Why does wire access matter?
The wire normally needs a through path or start hole, so cutting access must be confirmed from the drawing.
What affects wire EDM tolerance?
Material, thickness, wire diameter, flushing, pass strategy, feature geometry and inspection method affect tolerance.
Can wire EDM cut blind cavities?
Blind cavities are normally reviewed for sinker EDM because wire EDM requires a through-wire cutting path.
What should be sent for wire EDM review?
Send drawings, material grade, thickness, tolerance, surface finish, quantity and inspection requirements.
