Designed for wet-blast cleaning, descaling and pre-polish treatment of dies or molds, Guyson’s Vaqua slurry blasting system features a gun manipulator that moves the blast nozzles vertically and horizontally in a repeatable, programmed routine. Two banks of four guns are bracketed at the appropriate angles and offsets on the X-axis arms of the manipulator so that both faces of a workpiece can be blasted simultaneously. Controlled and adjustable traversing of the blast guns in two axes enables thorough, consistent coverage of components as large as 30" in diameter, and blast treatment can be concentrated on specific target surfaces, if necessary. All rotating parts of the precision ballscrew/ballnut actuators are located on the roof of the machine, outside the wet and abrasive environment of the blast chamber.
The 72" × 72" wet-blasting machine also offers a 1,500-lb-capacity powered transfer cart with a custom-designed rack on which a component can be loaded by overhead crane or hoist. The blast enclosure, cabinet hopper and all structures exposed to the slurry are fabricated from polished 304 stainless steel. The interior walls of the process chamber also are lined with rubber curtains for abrasion resistance and noise abatement. A full-depth, swing-out side door fitted with a view window and safety interlocks permits access to the inside of the blast cabinet for inspection, adjustment and maintenance.
