PR Series Two-Slide Thread Rolling Machines
Profiroll PR series CNC two-slide machines deliver cold forming rolling force from 50 kN to 1000 kN. Built on rigid cast iron C-frames with Siemens 840D CNC, they support infeed and throughfeed rolling. Ideal for automotive shafts, precision worms, and aerospace fasteners.
- Cold rolling forming force range from 50 kN to 1000 kN with CNC servo control
- High-precision infeed and throughfeed rolling for metric and trapezoidal threads
- Statically and dynamically rigid cast-iron C-frame minimizing mechanical deflection
- Siemens Sinumerik 840D hardware platform with automated workpiece handling
3-PR Series Three-Rolls Thread Rolling Machines
Profiroll 3-PR three-rolls machines deliver symmetrical three-point force distribution for hollow parts. The centered workpiece design prevents thin-wall deformation during heavy thread forming. Widely utilized for electric motor hollow shafts, connectors, and thin-walled tubes.
- Symmetrical 3-point radial rolling force preventing part deflection and ovality
- Ideal cold forming solution for thin-walled workpieces and hollow rotor shafts
- High-precision thread and profile forming on hydraulic fittings and pipe joints
- Quick changeover spindle units equipped with micrometer trace alignment
Rollex and PB 200 Spline Rolling Machines
Profiroll Rollex and PB 200 cold forming systems roll involute splines, serrations, and gears. Their servomechanical drive ensures minimal cycle time and outstanding pitch accuracy without chips. Extensively used for automotive transmission shafts, rotor shafts, and steering pinions.
- Chipless cold forming of involute splines, serrations, and timing gear teeth
- Energy-efficient servomechanical drive chain with digital pitch synchronization
- Multi-spline rolling capability on single transmission shafts in one setup
- Full automation integration for high-volume automotive drivetrain production
SRS Circular Rolling Dies, Flat and Rack Dies
Profiroll tooling is crafted from premium tool steels with proprietary heat treatments. Circular dies feature the Spur-Referenz-System (SRS), eliminating manual trace finding during installation. The PROSurface BlackDiamond coating delivers extended tool life under extreme contact pressures.
- Circular dies with Spur-Referenz-System (SRS) for immediate trace-free installation
- Flat, planetary segment, and rack dies for high-speed fastener cold forming
- Proprietary PROSurface BlackDiamond wear-resistant coating extending die longevity
- Precision grinding for standard metric threads, trapezoidal profiles, and ball screws
URWA Ring Rolling Machines and Fastener Systems
Profiroll URWA machinery performs seamless cold ring rolling for bearing races and rings. High-speed Fastener equipment rolls threads at rates up to 1500 parts per minute using circular segments. They eliminate flash and ensure continuous metal grain flow throughout the formed part.
- Seamless cold ring rolling technology for bearing races and aerospace rings on URWA
- High-speed Fastener machinery reaching throughput of up to 1500 pieces per minute
- Chipless metal forming preserving continuous fiber flow and mechanical strength
- Automatic bowl feeding, high-speed sorting, and inline optical inspection integration

The modular design integrates seamlessly into automated handling lines with gantry loaders and robotic workpiece feeding.
Engineering Sizing and Cold Rolling Process Parameter Selection
Selection of Profiroll cold forming equipment requires calculating required rolling force from 50 kN to 1000 kN, evaluating infeed or throughfeed kinematics, and selecting appropriate circular dies or flat racks.
Accurate pre-rolling workpiece diameter calculation is critical to ensure proper thread profile filling without over-rolling or crest burrs.
For hollow shafts and thin-walled tubular components, three-slide 3-PR machines provide balanced radial support preventing workpiece distortion. SpareX application engineering teams assist manufacturers worldwide in tooling layout, forming cycle optimization, and equipment commissioning.
