Non-contact

The non-contact nature of EDM train is a significant advantage that sets it apart from traditional cutting methods. In conventional cutting processes, such as milling or grinding, the cutting tool comes into direct contact with the workpiece, resulting in tool wear and the need for frequent tool replacement.

However, in EDM train, the wire electrode never touches the workpiece. Instead, a dielectric fluid is used to create a small gap between the wire and the workpiece. This gap prevents direct contact and eliminates tool wear. As a result, EDM train tools can last significantly longer than traditional cutting tools, reducing downtime and maintenance costs.

Furthermore, the non-contact nature of EDM train eliminates the need for expensive tooling. Traditional cutting tools, such as milling cutters and grinding wheels, can be costly to purchase and maintain.
