Robotic finishing machine blasts shot or grit

Guyson Corp. has introduced a new version of its RB-RSSA-8 robotic blast system, designed for cleaning and surface preparation of machined aerospace castings using either shot or grit media.

The system has a FANUC Robotics LR Mate-200iD 6-axis robot mounted on the reinforced back wall of the blast chamber to accommodate a variety of components. A 24-in.-dia., servomotor-driven turntable is adapted to accept the component-holding fixtures for all parts to be blasted; the radial orientation of the component is coordinated as a seventh axis by the robot’s R-30iB controller. A jib crane mounted on the roof of the blast enclosure and a rubber-flapped crane slot facilitate loading of heavy parts onto the table, which has a weight capacity of 250 lbs.

The media reclamation and delivery system is configured to enable separation of stainless steel shot and aluminum-oxide grit media fed to two different pressure pots of 2.3-cu.-ft. capacity. Depending on the particular components to be treated, an operator connects either the blast hose from the grit-blast pressure vessel or the shot-blast pressure pot.
