Guyson Corp.’s Model RB-9 robotic grit-blasting system is designed to enable consistent production of a specified finish on a wide variety of complex-shaped components for precision and flexibility in critical surface preparation work.

 

A six-axis robot serves as a nozzle manipulator when paired with the rotary table blast cabinet. Rotation of the turntable is powered by a servo motor and controlled as a seventh axis of robotic motion, allowing accurate positioning and movement of the work piece during automated blasting routines. According to the company, this allows the system to maintain a specific nozzle angle, offset (stand-off distance) and surface speed as it follows the intricate contours of components in execution of the programmed grit blasting process. Optionally, the system can be equipped with a crane slot in the roof of the blast cabinet to facilitate loading and unloading of heavy workpieces by an overhead hoist. Access to the blast enclosure is provided by two full-width doors with abrasion-protected view windows. The entire blasting chamber and turntable are lined with quarter-inch-thick bonded rubber sheeting to resist the abrasive effects of harsh grit media.

 

Available with either suction-blast or pressure-blast media delivery, the system  can also be set up with an enhanced media reclamation system that includes a vibrating screen classifier to separate larger or smaller particles from the blasting grit of the exact mesh size specified for the surface preparation process. The robotic grit-blast system can also feature media level sensors and an automatic dispensing hopper to replenish the supply of blasting grit before a low media level could compromise the precision finishing results.

 

The unit is available with a freestanding control console with a touch-screen panel. Blast process parameters associated with up to 100 different robotic blasting routines are stored by the system's programmable logic controller. Prospective users are invited to submit sample components for free laboratory testing and application engineering evaluation.
