of thread rolling
Thread production is characterized by extreme quality requirements - because the fasteners in cars and machines have to withstand very high loads. Especially when it comes to combining this high quality with high speed for low cycle times in large-volume production, LMT Fette provides the solution with the EVOline rolling head generation. The EVOline tangential rolling head is the first product development in this segment to combine 3D printing design with Industry 4.0 possibilities.
Additive manufacturing of the
rolling head arms
Through the use of additive manufacturing, the component structures of the EVOline tangential rolling head could be optimized in terms of force flow, resulting in a significant increase in breaking strength. It was also possible to integrate adjustable flushing and cooling nozzles in the rolling head hinge, for optimized volume flow. In order to increase reliability and efficiency in the process, the Smart Services area is also being continuously expanded. The aim is to tailor the tool even more specifically to the individual application and thus achieve additional improvements in the customer's overall process. The other product features and the associated customer benefits are synonymous with the EVOline family: Maximum process reliability with safe tool handling ensure a noticeable increase in the efficiency of the rolling heads.
at a glance

- Chip protection through individual covers and integrated flushing nozzles
- Tool-free installation and removal of the rolling head
Possible applications of
tangential rolling heads
Tangential rolling heads were developed primarily for rolling behind a collar diameter. The mode of operation is therefore by the plunge method. Tangential thread rolling heads can be mounted on all lathes that have an automatic infeed.
In particular, tangential thread rolling heads are used for the following threads and applications:
- Threads behind a collar
- Extremely short threads
- Threads with very short run-out (approx. 1x pitch)
- Knurling according to DIN 82
- Form rolling
Threads rolled with a tangential rolling head have all the advantages of chipless thread production.
Labeling instructions on the rolling head components simplify correct assembly as well as the identification of spare parts during disassembly. And: Handling convenience increases even more because the entire rolling head can be installed and removed without tools.
The EVOline tangential rolling head is available in five sizes covering thread diameters from 1.6 to 34 millimeters.
Faster, cost-saving and error-free
Due to a production expansion, a manufacturer of fasteners made a conscious decision to update the proven inventory system and switch to the EVOline generation of tangential rolling heads from LMT Tools.
This innovation within the system brings numerous advantages: In particular, the improved tool handling is thrilling. Quick, easy and error-free roll changes thanks to defined installation positions, simple and precise fine adjustment of the roll diameter via a central adjustment spindle, and tool-free installation and removal using quick-release bolts: The convenient operability makes daily work much easier. This has an impact on the entire production process, which is now significantly faster, leaner and more cost-effective.
