Innovations are expected from industry leaders, and Fenn's Torin® designs and builds machines that serve as the benchmark for the most innovative advances in the spring coiling and wire forming industries to dates.

A new level of performance can now be achieved with Fenn's Torin® line of camless spring coilers. Their full line of CNC 3, 4 & 5 axis machines represent state-of-the-art spring production equipment and performance.

Unlike other machines which require unique mechanical linkages and cams for each job, Fenn's Torin® CNC machines start producing in the time it takes you to enter your program. Should job priorities change, you can simply stop the machine and recall the desired program to quickly modify the production requirements and new product out-put.

Multi Axis CNC Camless Spring Coilers
Torin CNC machines are easily set up. What takes hours to set up for some mechanical machines is reduced to minutes on Fenn's Torin®’s new generation of CNC spring coilers. Now, small production runs can be profitable because a recalled spring can be quickly and accurately produced. Preset production count automatically stops the machine when the desired production run is reached.

Servo Motors…The Heart of Fenn's Torin®’s CNC Spring Makers
The Fenn's Torin® CNC Springmakers are designed for the full range of traditional wire sizes, but differ from the mechanical counterparts by being fully servo controlled. The feed, diameter, pitch, torsion and coiling point axes are directly driven with externally commutated AC brushless servo motors. There are no cams or associated levers and linkages used, and there are no motor brushes to wear out. Torque transmission on the diameter, pitch, torsion and coiling point is done through pre-loaded ball screws, thus eliminating backlash effects. The servo motors have a very high torque-to-inertia ratio to maximize responsiveness.

Fenn's Torin® CNC Spring Coiler Features
Interchangeable tooling. Fenn's Torin®’s standard mechanical spring coiler tooling is utilized in most cases.

Wider range of springs can be produced. There is increased tool travel on pitch, diameter and torsion over the mechanical machine. This opens up the scope of the CNC over mechanical equivalents.

Increased set up flexibility allows for the use of the hydraulic feed roll pressure and cut off. This cut off feature can be independently activated at any time during the set-up process, saving valuable time.

Extremely close tolerances. These are superior to mechanical springmakers. Servo motors and precision hardened pre-loaded ball screws on diameter, pitch and torsion provide a zero backlash operation.
