The YF-CNC-1245 CNC Camless Spring Forming Machine is designed for manufacturers that require greater forming power, stable wire feeding, and flexible production of medium-diameter spring products. Equipped with a 12-axis servo-controlled system, the machine processes wire diameters from 1.2 mm to 4.5 mm and is suitable for producing torsion springs, double torsion springs, compression springs, special-shaped springs, spring clips, and complex wire forms.
Unlike traditional cam-driven spring machines, the YF-CNC-1245 uses independent servo-controlled forming slides instead of mechanical cams. Operators can control feeding, wire rotation, mandrel rotation, spinner movement, and forming tool positions through the CNC system.
This configuration helps reduce setup time, improve forming accuracy, and make product changeovers more efficient.

The YF-CNC-1245 uses a coordinated servo system to control the complete forming process.
The 5.5 kW wire feeding servo controls material length and feeding speed.
The 2.9 kW wire rotation servo rotates the wire to create complex three-dimensional spring shapes.
The 1.2 kW mandrel rotation servo provides additional control during coiling and forming.
The 1.0 kW spinner servo supports spring end forming and special bending operations.
Eight independent 1.2 kW servo-controlled slides position the forming tools around the working area. This allows different tools to operate independently according to the programmed sequence.
The machine can process various spring wire materials within the specified diameter range, including:
Carbon Steel Wire
Stainless Steel Wire
Spring Steel Wire
Music Wire
Alloy Steel Wire
Galvanized Steel Wire
Copper-Based Wire Materials
Actual production capability depends on material hardness, tensile strength, spring geometry, and tooling configuration.
