Many different types of wet blasting systems are suitable for robotic automation. In most cases, the robot is integrated with the slurry-blast cabinet as a nozzle manipulator, with one or more wet blast guns bracketed to the end of the articulated arm. Rotary spindle wet-blast systems may have a servomotor drive, so the rotation or orientation of the spindle can be controlled as a 7th axis of robotic motion. A rubberized, laminated fabric skirt seals the wall of the blast enclosure and isolates the robot from the wet blasting process. While executing the programmed motion routine, the robotic wet blast system accurately maintains the correct nozzle angle, stand-off distance and surface speed.

This work-cell-sized model brings a new level of precision to rotary spindle blasting and surface finishing. A single suction-blast gun or pressure-blast nozzle is manipulated by a compact robot like the Fanuc LR Mate 200iC, saving a great deal of compressed air (energy) compared to multiple-gun systems. The rotary spindle is usually servomotor driven and controlled as a 7th axis of robotic motion.

In this single spindle design, a compact nozzle-manipulating robot, such the 6-axis Fanuc LR Mate 200iC is rigidly suspended from the removable roof of the blast enclosure. Available with suction-blast or pressure-blast media delivery and a single blast gun or nozzle, the RB-600 has a servomotor driven spindle mounted on an automatic swing-down door that presents the finished component at a convenient height and position at the loading station.

Capable of processing larger components, this model is popular as a pressure-blast system for precision surface preparation. A mid-size robot is generally mounted behind the blast cabinet and directs a single nozzle, exactly repeating the programmed process routine associated with each component. The spindle or up to a 42-inch diameter table is normally servomotor driven and controlled as a 7th axis of coordinated robotic motion.

In this robotic blast machine design, two servomotor-driven spindles are housed in a 180-degree indexing rotary drum. Inside the blast chamber, the fixtured component is purged by core air as it is exposed to the blast from a single pressure-blast nozzle precisely directed by a mid-size robot, such as the ABB IRB-140. Unload/load takes place during the blast cycle, so idle time is kept to a minimum.

This model is based on our expanded 2-spindle indexer, but normally has a single suction-blast gun or pressure-blast nozzle directed by a 6-axis robotic nozzle manipulator. The spindles are typically servomotor driven and controlled as a 7th and 8th axis of robotic motion, so the fixtured component may be rotated at adjustable speed or presented to the blast in a specific orientation for complete coverage. The ability to constantly maintain the correct blast angle, offset and surface speed while tracing contours of the component with a single gun results in a more consistent blast process with significant energy (compressed air) savings compared to multiple-nozzle machines.

Our dual arm robotic blasting cell has two side-by-side process chambers joined in the middle by a vertical sliding door. Both articulated arms can be equipped for component handling to blast each part and pass it to the other chamber for a second operation, or one arm can be fitted-out to manipulate a blast gun. Configured according to your own requirements, the RB-2+2 offers great multi-tasking flexibility.

Designed for single-piece-flow processing, the Model RB-6 has a component-handling robot located in an antechamber between the front loading station and rear blasting enclosure. Using a custom-designed gripper, the robot grasps the part, then manipulates it under a single blast gun or pressure-blast nozzle, constantly maintaining the correct angle, stand-off distance and surface speed.

For precision blast treatment or surface preparation of extra-bulky or long components, including aircraft structural parts, Guyson designs and builds custom-engineered systems with a 6-axis robot riding on a rail the runs the length of the blast cabinet. The linear travel of the nozzle manipulator is controlled as a seventh axis of robotic motion. Multiple rails enable two or more robot arms to be active in the same blast system, when required.

In this 40 × 40-inch machine, one or two suction-blast guns are positioned over the mouth of the removable perforated steel basket to cover the batch of small components as they turn over. The working load capacity is approximately one-third cubic foot or 55 pounds of components. Various basket perforation sizes, coated baskets and mini-baskets for very small batches are available.
