The cold-forming method requires an extremely rigid and strong machine.
The new Fimat rolling machine has been designed and built in order to meet any demand of strength and solidity needed to obtain high-quality results.
Special attention has been paid to the machine versatility and flexibility, thanks to Fimat wide experience in this sector.
Our base machine is designed to allow the use of several special solutions, in compliance with the various production requirements of the customer.
The external tailstock support can be assembled both on the upper and on the lower part of the machine, in accordance with the work piece loading/unloading specifications.
Special working cycles can be planned and customized, according to the particular demands of our clients.
Depending on machine features, it is possible to perform multiple rolling operations with just one work piece load by contemplating:
*Side by side racks.
*Intermediate stop of the working stroke.
*Work piece rotation and opposite side processing.
*Axial shifting of the work piece.

- Cold rolling of internal and external synchro-sliding gears or pinions for use on light or industrial vehicle mechanical gear boxes,
- Execution of involute rake forms with single or double slopes, or parallel to the spindle profile or original cut form,
- Operation guaranteeing perfect concentricity of the forms executed due to the accuracy of the workpiece centering on the workstation,
- Rigidity, accuracy, reliability of the clamping / rolling workstation,
- Its NC version, with a hydraulic axis, fully controls forces and movements developed during rolling in order to optimize the rolling and indexing cycle ; allows programming of the main parameters from the machine operator panel: Roll speed and direction of rotation, Rolling time in each direction of rotation, Speed of movement and positioning of the carriage supporting the pressure roller or the roller or the roll, Min-max rolling forces or combined with workpiece positioning.
- Various versions with manual or automatic loading, with multi-articulated robot or handler integrated in the machine,
- Fast changes of production runs, automatic recognition of workpieces,
- Machine conforming to EC standards.

Spline cold rolling machine:
Cold forming of equally spaced teeth on either cylindrical or slightly tapered workpieces : involute straight or helical splines, serrations and knurling.
Principals:
- Fixed distance between the forming tools centrelines during the working cycle.
- Circular tools with evolutive profile.
- Simultaneous forming of adjacent forms : threads, circular grooves, helical oil grooves.
- Forming of splines with snap ring groove.
Machine description:
- Quick and accurate roll matching, easy corrections at any time.
- Working distance between tools symmetrically, precisely, continuously adjustable with or without parallel correction.
- Display of matching and centre distance adjustment values.
Large cast base to eliminate vibration and deformation.
- Conform to CE regulations.
- Possible to recognise multi workpieces, versatility between manual and automatic modes.
- Production rate: up to 600 pieces/hour depending on automation.
- Optional hydraulic control assistance for tool change.
- Optional mechanisation of different adjustment commands.
- Two versions available, depending of form of workpieces, loading and utility modes.

FIMAT presents the new RL/EM line of NC Spline Rolling Machines with the rack holder slides driven by an electromechanic system, rather than hydraulic. The use of the electromechanic drive (by 2 controlled axes) of the slides, bring some serious benefit:
- Higher machining quality.
- Reduced machine layout by removal of the hydraulic pack.
- No heat and pollution generation.
- No more concerns relating to disposal of the used hydraulic oils with consequent reduced environmental impact and costs.

External profiles - The economic production of external spline profiles with first class quality is a current and existential challenge for manufacturers and suppliers everywhere. Now PROFIROLL proudly presents the ROLLEX-Series - the most popular machines for realization of these special tasks. Additionally the PROFIROLL team enlarges the product variety countinuously to serve your interests.
Besides spline rolling applications PROFIROLL offers a wide range of finish or burnishing rolling solutions.
Internal profiles - Regardless there are heavy demands of back taper rolling or claims regarding the production of internal spline profiles: PROFIROLL fulfils your requirements with the ROLLIN and the PWI 120 CNC/AC. These machine systems will not only help to shorten your cycle time they will even prevent every chip development or loss of material.

With the ever increasing demand for high accuracy, small batch quantities and high tensile materials, the requirements of thread and profile rolling techniques have changed. In the past simple pressure actuated one slide machines were used. Today one, two and three slide CNC/AC controlled machines are required.
