Pressure-Blast System performs precision finishing.
January 16, 2008 -
Rotary indexing spindle-blast machine, RXS-1400, uses direct pressure media delivery and media reclamation features to precisely control surface roughness of components. Measuring 102 x 94 x 78 in., blast cabinet features wrap-around work table and vacuum return media catch-tray at front loading station. System also incorporates 6 sealed and double-shielded ball bearing spindles, 20 ft³ capacity pressure vessel, and 7 adjustably mounted pressure-blast nozzles.
Guyson Corporation has introduced an expanded rotary indexing spindle-blast machine with direct pressure media delivery and special media reclamation features to precisely control the surface roughness of components. The Model RXS-1400 blast system is adapted for production use in preparation of surfaces prior to application of advanced functional coatings.
The blast cabinet, with its wrap-around work table and vacuum return media catch-tray at the front loading station, stands 78 inches high, 94 inches wide and 102 inches deep (1.98 x 2.44 x 2.59 meters). Extra wide vertically sliding doors allow processing of components up to approximately 20 inches (500 mm) in diameter.
Six sealed and double-shielded ball bearing spindles are equally spaced around the circumference of the RXS-1400's rotary table. The standard weight capacity of each spindle is 55 pounds (25 kg). A high quality cam indexer provides extremely accurate positioning of the spindles as they move from the loading station to blast and blow-off locations in the finishing enclosure, then return to the front unload station. The radial indexer is so exact that it is fully compatible with any type of automated loading facility, including machine-tending robots or pick-and-place devices.
A 20 cubic foot capacity pressure vessel with abrasion-resistant boron carbide grit valves meters blasting media to 7 pressure-blast nozzles clustered around two blasting stations in the blast chamber. Adjustably mounted at the optimum angles and distances from the components, three nozzles programmably traverse vertically at one blast station, while four nozzles traverse horizontally at the second blast station. Nozzle motion is synchronized with controlled, adjustable and programmable rotation of the fixtured component to ensure thorough and repeatable coverage.
Media reclamation in the precision finishing system is enhanced with the addition of a vibrating screen classifier in the cyclone separator and pressure vessel stack-up. The blast system manufacturer claims that media classification enables the tightest control over blast particle sizing, delivering only screened grit to the nozzles and yielding the most consistent surface roughness and uniformity of the specified texture.
The specially configured controls system includes a touch-screen interface for simplified machine programming and monitoring, as well as software to permit data logging and documentation of all blasting parameters to ensure a high level of process integrity.
Prospective users of automated blasting systems are encouraged to submit sample components for free laboratory test cleaning and application engineering evaluation at the machine builder's factory in northeastern New York State.
