LMT Fette creates wireless thread rolling
A
LMT Fette product story
Edited by the Manufacturingtalk editorial team
Aug 20, 2008
LMT's Fette division has developed a thread rolling head that uses Bluetooth technology to control the rolling cycle and monitor the process.
Available from LMT (UK) in Coventry, the ES 16 'intelligent' radial rolling head will roll form threads between 12mm and 22mm diameter and up to 29.6mm thread length in-cycle on almost any CNC machine tool.
The tool head can be used either statically or in rotating applications and be mounted on the machine via shank or flange fittings.
The thread rolling process is faster for producing external threads and provides a stronger thread with an improved burnished surface finish.
Within the rolling head is an integrated power amplifier, a contact sensor and a magnet to control the rolling cycle that is initiated automatically through the wireless interface.
The battery that powers the lifting magnet will perform more than 10,000 work cycles and can be quickly exchanged and recharged.
An integrated interlock prevents the rolling head opening during the rolling process and the internal electronics are shielded from any external influences.
A control panel displays data such as battery condition, confirmation of the Bluetooth connection and 'Ready to Process' indication signals that can be generated up to 50m away.
An important advantage achieved with the design of the electronic head is the simplification of the normal mechanical elements.
