EDM Machining Service

1. Setup

A tool electrode (typically made from copper, graphite, or tungsten) and a workpiece are submerged in a dielectric fluid, often deionized water or oil. CNC control systems guide the movement of the electrode to follow the desired shape.

2. Spark Generation

A controlled electrical discharge (spark) is generated between the tool electrode and the workpiece, creating intense heat (8,000-12,000°C).

3. Material Removal

The heat from the sparks vaporizes a small portion of the workpiece material at the spark contact point. The removed material is carried away by the dielectric fluid.

4. Repetition

Thousands of sparks are generated per second, which gradually erodes the material to the desired shape.

5. Final Result

This method allows for extremely fine cuts and precision, even on materials like hardened steel, titanium, and superalloys.

Materials For EDM

The materials suitable for EDM machining can be broadly categorized into hard metals, conductive metals, and others, each encompassing specific materials with unique properties.

CNC Steel Drilling

Hard Metals

EDM is ideal for hard metal materials (like titanium, tool steel, tungsten) because it doesn’t rely on cutting forces, which are challenging with traditional methods.
CNC Wood Drilling

Conductive Metals

EDM requires the material to be electrically conductive, which is why it efficiently machines metals like aluminum, brass, copper and some alloys.
CNC Plastic Drilling

Non-metals

Non-metals like graphite and carbides, though difficult to machine with conventional methods, can be processed with EDM due to their electrical conductivity.
