Guyson’s Model RB-600 robotic blast machine is designed to precisely repeat programmed surface preparation routines on individual components and automatically process a tray of parts without interruption.
The machine uses a six-axis FANUC LR Mate 200iC robot as a component manipulator. The articulated arm mounted in the grit-blasting chamber is fitted with a pneumatically actuated gripper and a tailored suit of laminated fabric that isolates the robot from the harsh abrasive environment. Inside the blast-finishing cabinet, a single pressure-blast nozzle is rigidly bracketed in position within easy reach for the robot to hold the component in the blast stream at the correct angle and distance to the nozzle, turn and move the part at the right surface speed for thorough surface preparation, and efficiently follow the programmed tool path to ensure complete coverage without over-blasting.
Robotic motion programs and blast processing recipes for more than 50 different components can be stored and recalled instantaneously. No set-up time or adjustments are required to change over from one part number to another, and trays of components can be processed in any sequence.
The robotic grit-blast system is said to offer increased throughput over manually operated blast cabinets, as well as energy savings from reduced compressed air consumption and low-energy LED lighting, and improved finish consistency.
