When Wire EDM Is the Right Process
Wire EDM is considered when electrically conductive material, geometry or low-force cutting requirements make conventional tooling less suitable.
Thin or Delicate Features
Review narrow sections and delicate profiles where low cutting force helps protect the geometry.
Complex Profiles & Narrow Slots
Produce intricate contours and slots that are difficult to reach with a rotating tool.
Controlled Feature Relationships
Plan profiles, slots and positions from drawing-defined datums and inspection requirements.
CUTTING CAPABILITIES
Wire EDM Capabilities
Precision Profile Cutting
External shapes, contours and narrow features reviewed from the drawing.
Internal Profiles & Start-Hole Cutting
Start-hole drilling is available for closed internal profiles after drawing review.
Taper / Angled Cutting
Typical taper review: up to ±3° over 80 mm; confirmed against the selected machine, workpiece thickness and drawing.
Prototype & Production Cutting
Drawing review for one-off parts, pilot quantities and repeat orders.
GEOMETRY EXAMPLES
Representative Wire EDM Part Geometries
Generated geometry studies show the kinds of features that can be reviewed; they are not customer parts or project records.
Hardened Insert Geometry
Intricate outlines, reliefs and locating features.
Internal Profile Plate
Closed contours reached through reviewed start holes.
Thin-Slot Component
Narrow slots, thin walls and delicate profile transitions.

Engineering Review Before Wire EDM
Wire access, geometry, material and inspection intent are aligned before a machine route is confirmed.
The review confirms whether the requested geometry is suitable for Wire EDM and identifies any points that require clarification before quotation.
Material Conductivity
Confirm the specified material is electrically conductive and suitable for Wire EDM.
Start-Hole & Wire Access
Review entry locations for every closed internal profile.
Kerf & Internal Geometry
Review narrow slots, internal corners and transitions against the selected route.
Part Thickness & Taper
Confirm workpiece thickness, taper direction and the drawing-defined relationship.

Slot / Feature Width
Measure suitable narrow features with confirmed equipment.
Hole & Feature Position
Check positional relationships between profiles, holes and datums.
Inspection Records
Agree report scope and critical characteristics before production.
Available inspection equipment: CMM, Height Gauge, Micrometer and Caliper.

QUOTATION INPUTS
What Affects Wire EDM Cost & Lead Time?
Quotation is based on the reviewed drawing and production requirements, not a single generic rate.
Material & Thickness
Material grade, heat-treatment condition and cut height affect the process plan.
Cut Path & Start Holes
Total contour length and the number of closed profiles affect machine time and setup.
Taper & Feature Complexity
Angled walls, narrow features and transitions require additional review and control.
Quantity & Inspection
Setup strategy, order volume and required records shape quotation and scheduling.
DRAWING PREPARATION
Wire EDM Design Guidance
Clear inputs make process review and quotation more useful.
Material Conductivity
State the grade and condition; the workpiece must be conductive.
Start Holes
Identify closed profiles and suitable wire-entry locations.
Internal Geometry
Dimension slots, internal corners and critical relationships.
Taper & Inspection
Define taper direction, datums and required inspection records.
WIRE EDM FAQ
Wire EDM FAQs
Answers are qualified by the drawing, selected machine and agreed inspection scope.
Upload Your DrawingWhat materials can be cut with Wire EDM?
Wire EDM requires an electrically conductive workpiece. HongKe reviews the material grade, condition, thickness, geometry and drawing requirements before confirming the process route.
Can Wire EDM cut hardened steel?
Yes. Wire EDM removes conductive material without conventional cutting force, so hardened steel and other conductive metals can be reviewed without relying on tool-edge hardness.
Do closed internal profiles require start holes?
Yes. A closed internal profile requires a reviewed start hole so the wire can be threaded through the workpiece. HongKe can provide start-hole drilling after drawing review.
What taper capability can HongKe review?
Typical taper review is up to ±3° over 80 mm. The achievable taper is confirmed against the selected machine, workpiece thickness and drawing.
How are Wire EDM features inspected?
The drawing determines the inspection plan. Available equipment includes CMM, Height Gauge, Micrometer and Caliper, selected according to feature type and required evidence.
What information is needed for a Wire EDM quote?
Provide a 2D drawing and available 3D model, material, quantity, thickness, critical features, tolerances, taper requirements, start-hole needs and requested inspection records.
