Our EDM Machining services are seamlessly integrated with other manufacturing processes, such as turning, milling, grinding, heat treatment, surface coating, and assembly, providing a comprehensive, end-to-end solution for custom part needs.

What Is EDM (Electrical Discharge Machining)? ​

The EDM process is a non-contact machining method that uses electrical discharges to remove material from the workpiece without applying mechanical stress. Ideal for cutting complex shapes and cavities in very hard metals, the EDM process submerges both the electrode and the workpiece in a dielectric fluid. This fluid controls the electrical discharge and flushes away eroded material. Repeated electric currents create tiny plasma zones that instantly melt and remove material, resulting in precise and intricate geometries.

Why Choose EDM Machining? ​

The EDM process is ideal for producing sharp internal corners, deep cavities, and fine details with exceptional precision and high-quality surface finishes. It excels in machining materials that are too hard for conventional methods or prone to hardening during CNC machining, all while avoiding deformation and tool wear. By using electrical discharges to remove material without applying mechanical stress, the EDM process maintains consistent precision and quality, even when working with hard and heat-sensitive materials.

Suitable Materials for EDM Machining ​

Virtually any conductive material can be processed by EDM Machining, making it especially effective for machining hard materials that are challenging with traditional techniques, such as tungsten, molybdenum, hardened tool steels, titanium, and austenitic stainless steels. For non-conductive materials like ceramics or plastics, special modifications or coatings are required to enable successful EDM Machining.
