Wire EDM vs. Sinker EDM
Wire EDM is usually better for through profiles and narrow slots while sinker EDM is better for blind cavities ribs and shaped mold features.
- Feature access
- Through cut or blind cavity
- Electrode strategy
- Tolerance and finish
Review EDM machining options by process, material, thickness, tolerance, surface finish and drawing requirement before sending an RFQ.
Browse EDM machining routes by process, material, thickness, tolerance, surface finish and surface-integrity concern. Use these routes to understand feature access, finish, tolerance and inspection requirements before project review.
Start from the question closest to your project. A buyer preparing drawings usually needs to confirm the EDM process, material behavior, geometry access, tolerance target and inspection requirement before sending an RFQ.
Use Wire EDM, Sinker EDM, Small Hole EDM Drilling or Micro EDM pages when the main question is feature access or machining route.
Use material pages when heat treatment, conductivity, hardness or surface-integrity risk may affect the quote.
Use thickness, tolerance, surface finish and drawing review pages when the part has tight features or inspection-driven requirements.
Use this snapshot to decide whether your part should be sent for EDM feasibility review. Final process selection depends on the drawing, material, tolerance, surface finish, quantity and inspection requirement.
Buyer Decision Topics
Compare EDM process fit, material behavior, tolerance, surface finish, surface integrity and drawing requirements before the project is reviewed.
Wire EDM is usually better for through profiles and narrow slots while sinker EDM is better for blind cavities ribs and shaped mold features.
A useful EDM RFQ should include drawing files, material grade and condition, thickness or feature depth, critical tolerances, surface requirements, quantity, and inspection expectations.
EDM tolerance depends on the process, material condition, section or feature geometry, flushing, finishing-pass strategy, datum control, and inspection method. Assign the tightest value only to the features that control fit and function.
EDM surface finish depends on process settings finishing passes material behavior and post-processing requirements. Critical surfaces should be marked clearly on the drawing.
Recast layer matters when the EDM surface affects fatigue contact sealing coating or safety-critical performance. These requirements should be stated before quotation.
Wire EDM fits conductive parts that need through profiles narrow slots sharp internal corners stable cutting force or accurate contours from flat or block stock.
Browse service, material, process-material, thickness, tolerance, surface finish and surface-integrity pages from the same Hub without searching through every EDM topic manually.
Primary EDM process pages for wire EDM, sinker EDM, small hole EDM and micro EDM service review.
Material-specific EDM review pages for steels, aluminum, copper alloys, titanium, nickel alloys and other conductive materials.
Pages that match a specific EDM process with a specific material grade for drawing-based feasibility review.
Wire EDM and micro EDM thickness-range pages for checking cutting access, stability, flushing and inspection concerns before quotation.
Tolerance and surface finish pages for drawings that specify precision, skim cuts, fine EDM finish or inspection-sensitive details.
Surface integrity, recast layer and post-processing review pages for EDM parts where edge condition, micro-crack risk or finishing requirements matter.
Upload STEP, STP, DXF, DWG, PDF, IGS, IGES or ZIP files. Include material, thickness, tolerance, surface finish, quantity and any inspection requirements so we can review process fit before quoting.
