EDM Process

High-Precision Electrical Discharge Machining for Complex Parts

Introduction

Electrical Discharge Machining (EDM) is a specialized manufacturing process that uses controlled electrical sparks to shape hard metals with extreme precision. Unlike traditional cutting methods, EDM does not rely on direct mechanical force, making it the preferred solution for working with materials that are too tough or delicate for conventional machining.

At Akinawa, our EDM capabilities enable us to achieve accuracy down to micron-level tolerances while producing complex shapes and fine details that would otherwise be impossible. This makes EDM an essential part of precision manufacturing, particularly in industries such as aerospace, automotive, medical devices, and high-performance tooling.

By leveraging the EDM process, we are able to deliver components with superior surface finishes, precise geometries, and consistent quality — ensuring that every part meets the highest standards of performance and reliability.

Our Capabilities

Wire EDM

Delivers precise cutting by using a thin wire electrode submerged in dielectric fluid. Perfect for producing complex profiles and fine contours with outstanding accuracy.

Die-Sinking EDM

Shapes molds and dies by sinking an electrode into the workpiece. Ideal for intricate cavities, sharp corners, and deep profiles that are impossible with traditional machining.

Micro EDM

Specialized for ultra-fine features and miniature components. Used in industries such as electronics and medical devices where micro-scale precision is critical.

High-Precision Cutting

Achieves tight tolerances with superior repeatability. Capable of maintaining micron-level accuracy for critical applications.

Hard Material Machining

Processes tough materials such as carbide, hardened steel, and exotic alloys. Ensures clean, precise results without damaging material integrity.

Surface Finishing by EDM

Provides smooth surfaces directly from the machining process. Reduces the need for secondary finishing and improves component performance.
