Success with system:
The axial rolling head generation EVOline
As the origin of our EVOline rolling systems, the EVOline axial rolling head is considered a reliable success driver. LMT Fette axial rolling heads have three thread rolls with pitch-free profile rings. The rolls swivel along their horizontal axis, so that the workpiece /the rolling head is axially shifted around the thread pitch with a full revolution. Since the rolls "traverse" axially over the workpiece, they can produce threads of any length and with diameters of 3.5 to 36 mm. Their modular design makes them particularly user-friendly to assemble and process safe.
Advantages of
cold forming threading
In a matter of seconds and with high precision, our rolling heads produce external profiles of all types by cold forming. The process of thread rolling offers you many advantages compared to cutting processes: Machining and cycle times are extremely short. At the same time, you achieve high thread strength and constant dimensional accuracy. You also benefit from excellent surface quality and long tool life. Last but not least, there is no chip accumulation. All of those advantages combined set the bar for chipless forming and high efficiency.
High efficiency
and process reliability
The production of threads with the EVOline axial rolling head comes with increased process reliability and maximum user friendliness. Thanks to the modular design of the interchangeable shanks, the entire system can be used flexibly and economically. The innovative, coolant operated clamping device is also very easy to integrate. The rolling diameter can be adjusted centrally by means of fine adjustment. A shank adaption ensures particularly precise concentricity and safe torque transmission.
Closing device EVOline
after rolling is before rolling
After our axial rolling heads have produced the thread or the required form, they open automatically. For the next thread, the thread rolls are brought back into working position by closing the rolling head. The closing clip and closing device (CCD) of the EVOline axial rolling heads make this process particularly user-friendly and flexible. Adapted between rolling head and shank and connected with the coolant supply, closing of the rolling head can be transferred from process time to the non-productive time of the machine. Closing by coolant (or even compressed air) can be integrated in the machine program by a simple function. Easy, safe and fast.
