1. Product Overview

The Large-Sized CNC Toroidal Winding Machine is a new-generation circular winding equipment specifically engineered to overcome the bottlenecks of traditional manual winding: high labor intensity, low working efficiency, and incorrect turns. Equipped with an automatic feeder and adjustable feeding device, it ensures seamless winding for diverse ring sizes. It stands as one of the most advanced large-sized circular winding solutions, delivering high precision, low noise, and energy efficiency.

2. Core Features & Advantages

• PLC Intelligent Control: Integrates automatic wire storage computation, automatic counting, automatic stop, and stop-memory functions, greatly simplifying operation and eliminating turn errors.

• Multi-Wire & Multi-Layer: The specialized multi-wire winding mechanism realizes dual-wire or multi-wire multi-layer winding, significantly enhancing productivity.

• Automatic Feeding: Adopts an automatic feeder with adjustable guiding to ensure stable wire tension and smooth winding for large toroidal cores.

• High Precision & Durability: Wide application range, low maintenance cost, energy-saving, and low noise, built for long-term industrial operation.

• Labor Optimization: Revolutionizes large coil production by replacing intensive manual work with CNC precision.
