• Control panel or CNC interface

The working process typically follows these steps:

1. The conductor wire is loaded onto a feed spool.

2. The machine spindle rotates at a controlled speed.

3. The wire guide moves horizontally to distribute the wire evenly.

4. Tension sensors maintain uniform winding pressure.

5. Insulation layers are inserted between winding layers when required.
