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 can manufacture a wide range of spring and wire products, including:
Compression Springs
Torsion Springs
Double Torsion Springs
Extension Springs with Formed Ends
Conical Springs
Variable-Pitch Springs
Special-Shaped Springs
Spring Clips
Wire Hooks
Wire Brackets

Custom Wire Forms
Its 12-axis servo system is especially suitable for products requiring multiple bends, precise leg positioning, wire rotation, or complex forming sequences.
The YF-CNC-1245 processes wire from 1.2 mm to 4.5 mm, making it suitable for stronger and larger spring components used in automotive, agricultural, furniture, appliance, and industrial applications.
Three pairs of wire feed wheels provide reliable gripping force and consistent wire movement. Stable feeding helps maintain product dimensions and improve batch consistency.
The 2.9 kW wire rotation servo allows the wire to rotate during forming, helping the machine manufacture complex three-dimensional springs and wire forms.
The machine combines wire feeding, wire rotation, mandrel rotation, spinner control, and eight forming slides. Each axis can be programmed according to the product geometry.
Production programs can be saved and reused. Repeat orders can be restarted by loading the relevant program and confirming the tooling setup.
Servo-controlled movements provide accurate positioning and consistent forming performance during continuous production.

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.
The YF-CNC-1245 is suitable for spring manufacturers serving industries such as:
Automotive Components
Agricultural Machinery
Furniture Hardware
Home Appliances
Industrial Equipment
Construction Hardware
Electrical Equipment
Fitness Equipment
Transportation Equipment
Custom Spring Manufacturing
Traditional spring machines rely on mechanical cams to control tool movement. Changing products may require cam replacement, mechanical adjustment, and repeated trial production.
The YF-CNC-1245 replaces these mechanical cams with programmable servo axes.
Main benefits include:
Shorter setup time
Faster sampling
Easier program modification
Greater spring-design flexibility
Better positioning control
Reduced mechanical adjustment
Efficient small- and medium-batch production
Easier repeat-order management
