싱커 EDM과 와이어 EDM: 올바른 프로세스 선택을 위한 종합 가이드

Understanding Electrical Discharge Machining (EDM)

Electrical Discharge Machining (EDM) revolutionizes metal fabrication by using controlled electrical sparks to erode materials. Unlike traditional methods, EDM requires no physical contact, making it ideal for ultra-hard metals like titanium or hardened steel.

Key Advantages of EDM:

• Handles materials up to 90 HRC hardness
• Achieves tolerances as tight as ±0.005 mm
• Eliminates mechanical stress on delicate parts
• Perfect for intricate geometries

How EDM Works: The Science Behind the Spark

EDM relies on three core components:

1. Electrodes: A tool (sinker) or wire creates sparks.
2. 유전체 유체: Flushes debris and cools the workpiece (oil or deionized water).
3. 전원 공급 장치: Generates rapid electrical discharges (up to 100,000 sparks/second).

사례 연구: A medical device manufacturer reduced part deformation by 40% using wire EDM for titanium surgical tools.

Sinker EDM: Crafting Complex Cavities with Precision

Sinker EDM (also called Ram EDM 또는 Die Sinking) uses a pre-shaped electrode to create molds, dies, and intricate cavities.

Typical Workflow:

• Design a graphite/copper electrode mirroring the desired cavity.
• Submerge the workpiece in hydrocarbon oil.
• Lower the electrode, eroding material via controlled sparks.

최상의 대상:

• Injection molding dies
• Sharp internal corners (e.g., turbine blade cooling channels)
• Blind keyways in hardened steel

Wire EDM: Precision Cutting for Intricate Designs

Wire EDM uses a thin brass wire (0.02–0.33 mm diameter) to slice through conductive materials. The wire never touches the workpiece, ensuring burr-free edges.

Why Choose Wire EDM?

• Cuts thicknesses up to 300mm
• Achieves surface finishes down to Ra 0.1 µm
• Ideal for prototypes requiring minimal post-processing

FAQs: Your EDM Questions Answered

Which EDM method is better for small batches?
Wire EDM typically offers lower setup costs for prototypes and limited runs.

Can EDM handle non-metallic materials?
No—EDM only works with electrically conductive materials like steel, titanium, or carbide.

How precise is EDM compared to CNC milling?
EDM achieves finer details (±0.005 mm vs. ±0.025 mm for milling) but is slower.

What industries benefit most from EDM?
Aerospace, medical, and automotive sectors rely on EDM for mission-critical components.
