CNC Speaker Coil Fly Winding Machine

The CNC speaker coil fly winding machine is a CNC machine used for winding self-supporting speaker voice coils using wires that have been coated in a thermo-plastic adhesive. The wire is heated by a hot air supply as it is wound onto the coil, and each turn is bound together using the adhesive. Finished coils are removed from the tool and automatically ejected from the machine onto a rotating unloading tool.

Main Features
- Fly winding design, multi-station winding & unloading
- Imported high precision ball screws & bearings, more accurate winding & guiding, longer life
- Two axis servo motor drive
- The CNC control system uses a microcontroller for simple operation and easy programming
- Low noise level
