These days 6 axes robots (if necessary with one or more external axes) are state of the art for coating of complex shaped surfaces. Such gun manipulators have become relatively cheap and feature different advantages:
high gun traverse velocity
complete communication between robot and coating machine controller
offline programming possible
We offers robots from different manufacturers. Our technicians are specialised on Kuka, ABB and Fanuc robots. However, there is no problem to impart that type of robot you are familiar with into a thermal spray installation.
