Robotic Shot Peening System

Guyson Corporation has introduced a 7-axis robotic pressure-blast shot peening system that is designed to support compliance with the most demanding process specifications and to enable automated peening of a wide variety of dissimilar components. The Model RB-10 was developed for technical surface treatment of gears and aerospace components.

The 60 x 60 x 60-inch blast cabinet is mated with a 6-axis robot, such as the Fanuc M10iA, as a blast nozzle manipulator. The shot peening machine's rotary table has a diameter of up to 52 inches and is servomotor driven to be controlled as a seventh axis of robotic motion.

Locating hardware is provided to allow interchangeable component-holding fixtures to be positively and repeatably positioned on the turntable.

During the shot peening cycle, the orientation of the component and the motion of the robotic nozzle manipulator are synchronized to precisely replicate the programmed tool path, following the contours of complex-shaped parts, yet constantly and accurately maintaining the required angle of shot impingement, the correct offset of the peening nozzle from the target surface and the right dwell or surface speed to control the cold working process.

The peening media delivery system includes an A.S.M.E.-certified pressure vessel of 3.5 cubic foot capacity fitted with high and low shot level sensors, a 3 cubic foot media storage hopper that automatically adds shot when a low level is detected and, if required, an electronic shot flow controller to continuously maintain the correct blast pressure and shot flow rate specified for the shot peening process.

In addition to a cyclone separator for dust extraction, the shot reclamation system includes a vibratory screen classifier to deliver only shot of the specified size, as well as a spiral separator to remove any peening shot that is not perfectly spherical.

For metallurgical shot peening applications in accordance with S.A.E. aerospace peening specification AMS 2432, Guyson offers a SCADA controls package combined with a custom-designed touch screen human-machine interface (HMI) to enable data verifying all critical process parameters throughout the shot peening procedure to be captured and logged for documentation purposes.

Prospective users of robotic shot peening equipment may submit sample components for
evaluation in the application engineering laboratory at the blast machine builder's factory in northeastern New York State.
