Guyson Corp. offers a seven-axis robotic grit-blast system that automatically changes between blasting tools to perform critical surface preparation work around the exterior of complex-shaped components, as well as recesses and interior part surfaces.
The multi-tasking robotic blast machine incorporates a six-axis Fanuc M-20iA robot rigidly mounted on a pedestal inside a 60 × 96-inch rotary table blasting cabinet. A custom-tailored suit of laminated fabric isolates the tool-changing robotic nozzle manipulator from dust and media, yet allows the full range of motion of the articulated robot arm. The turntable, bearing an interchangeable component-holding fixture, is servomotor-driven and controlled as a seventh axis of coordinated robotic motion, so the precise orientation and rotation of the workpiece is a programmed and repeatable element of the automated blast processing routine.
A storage compartment or “doghouse” on one side of the blast enclosure securely cradles and positively locates a straight pressure-blast nozzle attached to a custom-designed gun bracket. The doghouse on the other side of the cabinet holds a bracketed lance tool with an angled nozzle that can reach into hollow areas and narrow openings. Vertical sliding doors seal the blast chamber and separate the stored blasting tool from the machine’s abrasive environment.
According to Guyson, the machine’s tool-changing capability may be applied to more than two tools, and a variety of other types of blasting tools may be required for other specific process requirements. For example, separate selectable nozzles may deliver different shot or grit media sizes, or a non-blast tool may be included for certain processing operations.
