Understanding EDM and Able Wire EDM’s Expertise
Electrical Discharge Machining (EDM) is a unique manufacturing process that uses electrical sparks to shape materials, especially hard metals that are challenging to machine with traditional tools. Able Wire EDM specializes in various EDM services, including wire EDM, sinker EDM, and small hole EDM drilling. With over 30 years of experience, Able Wire EDM is known for exceeding expectations in precision manufacturing.
Let’s break down how EDM works, what makes Able Wire EDM a leader, and how you can benefit from their services.
What Is EDM?
EDM, or Electrical Discharge Machining, is a process that uses controlled electrical sparks to erode and shape metal components. This makes it ideal for crafting intricate or delicate parts from tough materials like tool steel, titanium, or carbide.
Key EDM Methods Used by Able Wire EDM
-
Wire EDM
Uses a thin, electrically charged wire to cut through metal — similar to a cheese slicer but using electricity. This method produces extremely precise edges and complex shapes. -
Sinker EDM
Involves a shaped electrode that sinks into the metal, creating cavities and fine details. Perfect for intricate dies and molds. -
Small Hole EDM (Hole Popping)
Specialized for drilling tiny holes with high accuracy. Used for starting holes for wire EDM or vent holes in hardened materials.
Step-by-Step: How EDM Works at Able Wire EDM
Let’s walk through the typical process when you work with an expert EDM job shop like Able Wire EDM.
- Design and Planning
- Your specifications and drawings are reviewed in detail.
- Engineers determine the best type of EDM process: wire, sinker, or hole drilling.
- Material Selection
- Suitable for metals that are electrically conductive.
-
Common materials include tool steels, stainless steel, titanium, carbide, and even exotic alloys.
-
Programming and Setup
- Advanced CAD/CAM software is used to program the cutting path.
-
Workpieces and electrodes (for sinker EDM) are prepared with exacting precision.
-
Machining Process
- In wire EDM, the part is submerged in a dielectric liquid.
- Electrical sparks jump from the wire to the workpiece, eroding material precisely along the programmed path.
-
For sinker EDM, the pre-shaped electrode descends into the material, creating molds or cavities.
-
Quality Control
- Finished parts are cleaned, inspected, and measured using high-precision equipment.
-
Able Wire EDM emphasizes accuracy and surface finish.
-
Delivery
- Final products are shipped following strict packing standards to protect precision surfaces.

Key Benefits of EDM at Able Wire EDM
- Unmatched Precision: Able EDM achieves extremely tight tolerances, which is vital for mission-critical applications.
- No Mechanical Stress: As there’s no physical cutting tool, fragile or thin sections can be machined without risk of deformation.
- Ability to Machine Hardened Materials: EDM can shape materials that are otherwise impossible to cut—like hardened steel after heat treatment.
- Complex Geometries: Intricate cavities, sharp inside corners, and fine holes are possible.
- High Surface Quality: EDM leaves a smooth finish, reducing or eliminating the need for secondary polishing operations.
Challenges and Solutions in EDM
Like any advanced manufacturing method, EDM poses some challenges. Able Wire EDM addresses these with their deep expertise.
- Slower than Conventional Machining: EDM is precise, not fast. To optimize schedules, Able Wire EDM uses efficient job planning and parallel machine operation.
- Material Constraints: The process only works with electrically conductive materials. Warehouse management and sourcing help ensure proper materials are always on hand.
- Potential Wire Breakage: Expert setup and continuous monitoring reduce the risk of wire snapping, preserving quality and consistency.
- Dielectric Fluid Maintenance: Meticulous machine maintenance guarantees the dielectric fluids are always in top condition, ensuring accuracy and repeatability.
Practical Tips for EDM Projects at Able Wire EDM
If considering EDM for your next project, keep these best practices in mind:
- Early Design Consultation
- Discuss your part’s tolerances, surface finish, and geometry with Able Wire EDM’s experts early to optimize results and pricing.
- Material Selection
- Stick with materials known for good EDM response (tool steel, stainless, titanium, etc.).
-
Ask about material availability and lead times.
-
Prepare Clear Drawings and 3D Models
- Supply detailed CAD files (.dwg, .dxf, .step, etc.) for precise programming.
-
Include all critical dimensions and tolerances.
-
Volume Planning
- For larger production runs, batch similar parts and plan efficiently to reduce cost per unit.
-
For prototypes, request quick-turn services for rapid iteration.
-
Post-EDM Finishing
- Discuss whether you require further polishing, heat treatment, or coating after EDM.
- Able Wire EDM may be able to coordinate secondary operations or recommend trusted partners.
Cost and Shipping Tips for EDM Services
Managing cost is crucial. Here’s how to get the best value from Able Wire EDM:
- Consolidate Orders: Larger batches reduce setup costs and machine downtime per part.
- Simplify Geometry Where Possible: While EDM can handle complexity, simpler features generally lower programming and machine time.
- Material Costs: Use standard sizes to avoid excess trimming or custom orders.
- Plan Shipping Carefully: EDM parts are precision-finished; request robust packing. For high-value or fragile components, specialty shipping may be warranted.
- Request Quotes Early: Able Wire EDM offers detailed quotes factoring in machining, inspection, packing, and shipping so you can budget accurately.
