EDM & complex processes

Reach the Geometry.Keep the Route Connected.

Part of Dawnmill’s Integrated Precision Machining Capabilities.

Dawnmill uses wire EDM and sinker EDM where part geometry, access or feature condition makes conventional machining inefficient or impractical.

Process applications

Wire or Sinker.Selected by the Feature.

The geometry determines which process is practical and how it connects with machining and finishing.

01

Wire EDM

  • Precision profiles and cutouts
  • Narrow slots
  • Controlled through-features
02

Sinker EDM

  • Recessed cavities
  • Blind internal features
  • Geometry formed by electrode
03

Combined Machining

  • CNC-established datums
  • EDM after rough or finish machining
  • Secondary features completed in sequence
04

Final Condition

  • Deburring and cleaning
  • Specified surface finishing
  • Dimensional verification

Technical specifications & process limits

Define the Range.Then Commit.

The range below shows what matters for this topic. The applicable process, limits and verification method are confirmed against the actual drawing, material and final condition.

TECHNICAL RANGEProject-specific values confirmed before production.
Processes
In-house wire EDM and die-sinking EDM integrated with CNC-established datums.
Best fit
Narrow profiles, controlled through-features, recessed cavities and geometry impractical for rotating tools.
Materials
Electrically conductive materials reviewed against thickness, feature condition and the complete process route.
Control focus
Wire/electrode access, stock allowance, datum relationship, corner condition and verification method.

EDM review

Use EDMWhere It Earns Its Place.

The process must fit the geometry and the wider route. We review access, stock, datum relationships and the final feature condition before confirming it.

DFM REVIEW01

Feature Access

  • Whether wire travel, electrode access and surrounding geometry support a practical operation.
  • How prior machining leaves stock and establishes datums for the EDM stage.
PROCESS CONTROL02

Corner & Surface Requirements

  • Feature shape, internal detail and delivered surface condition considered together.
  • Machine the references and prepare the required stock condition.
INSPECTION & RECORDS03

Datum Relationship

  • Keep EDM features tied to the references that define component function.
  • Use an appropriate dimensional method for the specified geometry.
PROCESS LOGICMachine the Datum. Reach the Feature.

CNC machining and EDM are coordinated so the difficult feature remains connected to the functional geometry of the part.

Feature control

Difficult to Reach.Still Clear to Verify.

The inspection approach is considered before the feature is produced, especially where access affects measurement.

CAPABILITY EVIDENCE

Wire EDM and die-sinking EDM performed in-house

EDM planned with CNC machining rather than as an isolated handoff

CMM or optical results, material certificates, FAI and CoC are available when agreed for the project.

Conventional Tools Cannot Reach It?

Send the geometry. We’ll review whether wire EDM, sinker EDM or a combined route is the practical option.
