Engineered for railway springs, mining equipment springs, construction machinery springs, and ultra heavy-duty industrial wire forming applications.
The YF-CNC-1280 is Yinfeng's ultra heavy-duty CNC camless spring forming machine developed for manufacturers processing spring wire from Ø3.0 mm to Ø8.0 mm.
Its high-power 12-axis servo system, four pairs of wire feed wheels, independent wire rotation, and eight heavy-duty forming slides provide the torque, stability, and forming capability required for large industrial spring production.
Unlike standard camless spring machines designed mainly for small or medium wire diameters, the YF-CNC-1280 is optimized for thick spring wire, high forming loads, and continuous production of large, high-strength components.

The machine is particularly suitable for parts requiring high forming force, multiple bending directions, wire rotation, and precise leg positioning.
Processing spring wire up to Ø8.0 mm creates manufacturing challenges that are significantly different from small-wire spring production.
Heavy spring wire requires:
Greater feeding force
Higher servo torque
Stronger wire gripping
More rigid machine construction
Better springback compensation
Stable multi-axis synchronization
Stronger forming tools
Reliable performance during continuous production
The YF-CNC-1280 addresses these requirements through a reinforced mechanical structure and a high-power servo configuration designed specifically for heavy industrial spring manufacturing.
The YF-CNC-1280 is equipped with a 15 kW wire feeding servo motor and four pairs of wire feed wheels.
This configuration provides:
Strong gripping force for thick wire
Stable feeding under high resistance
Accurate wire length control
Reduced wire slippage
Improved dimensional consistency
Reliable feeding during continuous production
Stable wire feeding is especially important when processing high-strength alloy spring wire and large-diameter materials.
The 5.5 kW wire rotation servo motor allows the wire to rotate independently during the forming process.
This makes it possible to produce:
Three-dimensional spring shapes
Complex torsion spring legs
Heavy double torsion springs
Multi-directional bends
Large custom wire forms
Independent wire rotation significantly expands the machine's forming flexibility compared with equipment that only supports forward wire feeding.
The machine uses eight independently controlled forming slides, each powered by a 4.5 kW servo motor.
These slides can be programmed to perform different forming actions, including:
Coiling
Bending
Pitch forming
Leg forming
End shaping
Multi-step wire forming
The independent slide structure allows the tools to work in a coordinated sequence according to the product program.
