In today’s high-precision manufacturing world, EDM Machining Services have become a critical solution for creating complex and high-tolerance parts. At Langhe Casting, we specialize in advanced EDM machining services tailored to industries that demand accuracy, repeatability, and clean finishes.
Whether you need components for aerospace, automotive, mold making, or medical applications, our Electrical Discharge Machining (EDM) capabilities ensure precision without compromise.
Wire-Cutting-EDM
EDM (Electrical Discharge Machining) is a non-traditional machining process that removes material from conductive metals using controlled electrical sparks. Unlike traditional cutting, EDM does not involve physical contact between tool and workpiece.
EDM is especially useful for:
Extremely hard materials (e.g., tool steel, titanium, Inconel)
Intricate shapes or internal cavities
Thin walls and fine tolerances
Sinker-EDM-Services
Langhe Casting offers multiple EDM processes to meet diverse design and engineering needs.
| EDM Type | Description | Typical Applications |
|---|---|---|
| Wire EDM | Uses a thin electrically charged wire to cut through material with precision | Dies, punches, extrusion tools |
| Sinker EDM | Uses an electrode and dielectric fluid to form complex 3D shapes | Molds, aerospace parts, internal cavities |
| Hole Drilling EDM | Designed for drilling micro holes using spark erosion | Cooling holes in turbine blades, injector nozzles |
Each method supports ultra-fine finishes, tight tolerances, and consistent quality.
Our services are engineered for the highest performance. Below are the major highlights of our EDM capabilities:
| Feature | Specification / Capability |
|---|---|
| Tolerance Accuracy | ±0.002 mm (or tighter on request) |
| Surface Finish | Ra 0.2 – 1.2 µm |
| Minimum Hole Diameter | As small as Ø 0.2 mm |
| Max Workpiece Hardness | Up to 65+ HRC |
| Supported Materials | Tool Steel, Stainless Steel, Titanium, Carbide, etc. |
| Max Workpiece Size | 1000 x 800 x 500 mm (custom options available) |
Langhe Casting integrates technology, expertise, and rigorous quality control in every EDM job. Here’s what sets us apart:
High Precision
Our wire and sinker EDM machines deliver unmatched dimensional accuracy, suitable for complex and micro-tolerance parts.
Wide Material Compatibility
We process all electrically conductive materials, including hardened steel, tungsten, copper, and superalloys.
Complex Geometry Support
EDM enables the production of sharp corners, deep cavities, and undercuts that are impossible with conventional machining.
No Mechanical Stress
Since there’s no physical contact, EDM prevents mechanical deformation—ideal for fragile or thin-walled parts.
Consistent Repeatability
Our CNC-controlled EDM systems ensure that each batch matches exacting standards, every time.
Hole-Drilling-EDM-Services
EDM machining provides the flexibility and control needed for industries with specialized requirements.
| Industry | Application Examples |
|---|---|
| Aerospace | Turbine blades, nozzles, combustion chambers |
| Automotive | Transmission components, fuel injectors, tooling dies |
| Medical Devices | Orthopedic implants, surgical tools, micro-instruments |
| Electronics | Connectors, heat sinks, micro-components |
| Mold Making | Injection molds, die casting molds, precision inserts |
Understanding the differences between EDM and traditional methods helps in selecting the right process.
| Feature | EDM Machining | Conventional Machining |
|---|---|---|
| Contact Required | No (non-contact process) | Yes |
| Material Type | Only conductive materials | Most materials |
| Tool Wear | Minimal to none | Significant over time |
| Complex Geometry | Excellent for intricate profiles | Limited |
| Heat Affected Zone | Localized (small) | Larger |
