The YF-CNC-1425 12 Axis CNC Camless Spring Machine is designed for manufacturers producing complex precision springs from Ø0.2–2.5 mm wire. It combines flexible CNC servo control with two enhanced forming movements: a No.1 forming slide that can move horizontally and vertically, and a mandrel system that can move forward and backward as a complete unit.
These additional movements provide more freedom around the forming center, allowing tools and the mandrel to change position according to different spring geometries. This makes the YF-CNC-1425 especially suitable for customized springs with complex legs, irregular ends, multiple bending directions, asymmetric structures, and demanding forming sequences.
Compared with conventional fixed-position forming structures, the YF-CNC-1425 gives spring manufacturers greater flexibility when developing new products, changing spring models, and optimizing difficult forming processes.

Wire diameter range: Ø0.2–2.5 mm
No.1 forming slide with horizontal movement
No.1 forming slide with vertical movement
Complete mandrel unit with forward and backward movement
Independent servo-controlled forming movements
Flexible tool positioning for complex spring geometries
Reduced mechanical adjustment during product changeover

English interface and customized control-system language service
One of the most important features of the YF-CNC-1425 is the enhanced movement capability of the No.1 forming slide.
Instead of operating only from a fixed position, the No.1 slide can move in both horizontal and vertical directions. This allows the forming tool to change its working position according to the spring structure and forming sequence.
Changes the forming-tool position around the working area
Provides additional forming directions for complex spring shapes
Improves access to difficult forming positions
Helps reduce interference between different forming tools
Supports more flexible bending and end-forming sequences
Makes tool positioning easier when changing to different spring structures
The movable No.1 forming slide is particularly useful when producing springs with:
Complex torsion spring legs
Multiple bending directions
Offset or asymmetric ends
Special hooks and mounting sections
Non-standard spring geometries
Customized multi-step forming requirements
For spring manufacturers producing many customized products, this additional slide movement provides more process flexibility than a conventional fixed-position forming tool.
The second major innovation of the YF-CNC-1425 is the complete mandrel system with forward and backward movement.
During spring forming, the mandrel position directly affects the available forming space and the relationship between the wire, tools, coil section, and spring legs. By allowing the entire mandrel assembly to move forward and backward, the YF-CNC-1425 provides another controllable dimension in the forming process.
Adjusts the mandrel position according to the forming sequence
Creates additional clearance between the mandrel and forming tools
Improves accessibility when forming complex spring ends
Supports different coil and leg configurations
Helps reduce tooling interference during multi-step forming
Provides greater flexibility when developing special spring structures
The movable mandrel works together with the movable No.1 slide to create a more flexible forming area. This is one of the key differences between the YF-CNC-1425 and conventional camless spring machines with more fixed forming positions.
The main advantage of the YF-CNC-1425 is not simply adding two movements. The real benefit comes from coordinating the No.1 slide movement, mandrel movement, wire feeding, wire rotation, and other servo-controlled forming tools within one CNC program.
For a complex spring, different forming steps may require different tool positions. The No.1 forming slide can move to a suitable horizontal or vertical position, while the mandrel can move forward or backward to create the required forming space.
This coordinated movement can help manufacturers simplify difficult forming sequences and improve the machine's adaptability to customized spring products.
The YF-CNC-1425 uses a 12-axis CNC servo-controlled system to coordinate the machine's forming movements.
Independent servo control allows operators to program movement position, timing, speed, and sequence according to the required spring geometry.
Flexible multi-axis movement coordination
Precise control of forming-tool positions
Stable repeatability during batch production
Faster adjustment for new spring designs
Reduced dependence on mechanical cam adjustment
Easy program modification during sampling
Suitable for high-mix and customized spring production
Traditional cam spring machines rely heavily on mechanical cam profiles and physical adjustment. A CNC camless spring machine uses independently controlled servo axes to create the required tool movements digitally.
For manufacturers producing multiple spring models, this provides several practical advantages:
Faster product setup
Easier forming-parameter adjustment
Reduced mechanical cam replacement
More flexible product development
Better suitability for customized orders
Faster repeat production using saved programs
The additional movable slide and mandrel functions of the YF-CNC-1425 further extend this camless forming flexibility.

The YF-CNC-1425 is a 12-axis CNC camless spring machine for Ø0.2–2.5 mm wire. Its key features include a No.1 forming slide with horizontal and vertical movement and a complete mandrel system with forward and backward movement.
The main difference is the additional forming freedom. The No.1 slide can change its horizontal and vertical position, while the mandrel can move forward and backward. These movements provide greater flexibility for complex spring forming.
The movement allows the forming tool to approach the wire from different positions, helping improve access to complex forming areas, reduce tool interference, and support special spring ends and multi-directional bends.
The mandrel can move forward and backward to adjust the forming position and available tooling space. This is useful when producing springs with complex coil, leg, hook, or end-forming structures.
The applicable wire diameter range is Ø0.2–2.5 mm. Actual forming capability also depends on wire material, tensile strength, spring geometry, and tooling configuration.
Typical products include torsion springs, double torsion springs, extension springs, compression springs, battery springs, contact springs, precision springs, special-shaped springs, and customized spring components.
