Short Answer
To compare EDM and Wire EDM Machines offers fairly, standardize application data, supply scope and acceptance criteria, then score fit, good output, quality, auxiliaries, support, total cost and risk with declared weights.
Normalize scope
List included and excluded machine, auxiliaries, tooling, software, installation, training, warranty, freight and services.
Technical fit
If the path is through-cut and wire can pass, wire EDM is a strong candidate. Blind cavities and electrode-transferred shapes usually point to sinker EDM.
Output and flow
Both require conductive material. Review heat treatment, start holes, workholding, surface condition and electrode manufacture where applicable.
Solution completeness
Define tolerance, roughness, acceptable passes and thermal-fluid stability. Unneeded precision adds time and cost.
Trial and support
Include wire or electrode, filters, dielectric, power, programming, supervision and maintenance, then compare cost per good part.
Cost and risk
Use total cost and a downside case. Score delay, currency, downtime, spares and skills risks. Do not weight price so heavily that it cancels trust and quality.
Frequently Asked Questions
Should a score be used?
Yes, with weights agreed before offers are opened.
How are different specifications compared?
Map every offer to common requirements and expose deviations.
When should the lowest price be rejected?
When it fails a critical requirement or creates higher cost or risk.
