1. Understanding Dual-Head EDM Technology

1.1 What is Dual-Head EDM?

Dual-head EDM machines feature two independent working heads that can operate simultaneously or independently on a single workpiece. This setup allows for:

- Parallel machining (two operations at once)

- Reduced idle time (one head can rough while the other finishes)

- Higher throughput (faster completion of complex parts)

1.2 Integration with Additive Manufacturing (AM)

Modern dual-head EDM systems often incorporate AM capabilities, enabling:

- Hybrid manufacturing (combining additive and subtractive processes)

- Repair and reconditioning of high-value components

- Complex internal cooling channels in molds and dies

This integration eliminates multiple setups, reducing errors and improving efficiency.
