Robot Helps with Lance Blasting System

For precision grit blasting and surface preparation of the inside diameters of industrial gas turbine components in manufacturing and repair operations, the robotic blast system integrates a Fanuc M-710iC robot as the lance manipulator.

This happens in an expanded process chamber with a servomotor-driven rotary table that is controlled as an auxiliary axis of robotic motion. The blasting enclosure is fabricated with an added rear vestibule to allow room for full movement of the pressure-blast lance as the robot follows the tool path required for coverage of complex-shaped internal surfaces, constantly maintaining the correct nozzle angle, offset and surface.
