Guyson Corp.’s RB-9 robotic blast system is specially adapted for glass bead peening in NADCAP-compliant manufacturing and overhaul operations that must perform the surface enhancement process according to AMS 2432 peening specifications, including peening of stage-one titanium fan blades.

The seven-axis glass bead peening machine incorporates a Fanuc M-10iA or comparable robot as a blast gun manipulator and a servo-motor drive that orients the machine’s turntable as a coordinated auxiliary axis of robotic motion. During a peening cycle, the robotic blast system constantly maintains the correct nozzle angle, offset and surface speed as it traces the contours of the part. The Fanuc robot design features a hollow wrist that enables the suction-blast gun’s air and media hoses as well as the separate blow-off nozzle’s air supply hose to be routed through the arm of the robotic nozzle manipulator.

The system includes a 36-inch-diameter, 500-lb weight capacity rotary table with T-slots that is mounted on a powered transfer cart to facilitate installation and changing of component-holding fixtures. The 48 × 48 × 48-inch glass bead peening cabinet features a rubber-flapped and covered channel in the roof of the blasting enclosure, and a 500-lb-capacity roof-mounted jib crane to ease loading and unloading of heavy components.

In addition to a cyclone separator for removal of dust and fines, the RB-9’s peening shot reclamation system includes a vibratory screen classifier to maintain strict control over shot sizing and a spiral separator to prevent non-spherical or fractured beads from being fed to the blast gun.

    Surface finish types for commercially supplied stainless steel sheet are detailed in various standards. ASTM A480-12 and EN10088-2 are two; BS 1449-2 (1983) is still available, although no longer active. These standards are very similar in that they define eight grades of surface finish for stainless steel. Grade 7 is “buff polished,” while the highest polish—the so-called mirror polish—is designated Grade 8
