Challenge
In the production of garage doors by Europe's largest garage door manufacturer, steel shafts needed to be lathed so that they could be welded by a MAG welding robot. Harsh ambient conditions and ground discharging (welding current) were the challenges here.
Solution
A servo rotary axis, in combination with a Zimmer rotary distributor and three-jaw gripper, was the solution here. The components were held securely by the three-jaw gripper. In the gripped state, the components were turned by the servo motor and the ground discharged via the rotary distributor.
