Worm screws welding
Helical tooling on bulk conveyors welding (picture above) and on conical pulp presses (picture below).
In the latter case, the Al Power MIDI motorized base is driven by Brushless motor with encoder and rack
and pinion transmission.
Rails are provided of ball bearings linear guides. Such features altogether create a friction – a free and precise joint tracking is performed by IG LAS system.
The control cabinet incorporates PLC/2 and the CNC axis to take care of the rotation, and the manipulator base speed to keep constant the helical weld speed on the conical job.
