Where EDM fits
Sinker EDM can help form blind cavities, narrow ribs and hard-metal features where conventional tools cannot reach cleanly.
RFQ preparation
- Highlight blind cavity depth and internal corner expectations.
- Clarify surface texture or post-polish requirements.
- Confirm whether electrodes or fixtures may be needed.
Engineering review
The review considers electrode strategy, burn area, material condition, expected surface texture and downstream finishing.
