Guyson SPRXS-900 Spin-Blaster Automates Batch Finishing
November 3, 2004 - Saratoga Springs, NY
Guyson Corporation has designed an indexing rotary spindle blast system that facilitates overall descaling, surface preparation and cosmetic finishing of components. The Model SPRXS-900 individually processes a dozen components per load.
The blast cabinet is 30 inches wide and 36 inches deep, with a large side door to provide access to the finishing enclosure for inspection, adjustment and maintenance. Hinged doors actuated by pneumatic cylinders seal the front of the cabinet at the load/unload station to keep operating noise levels low and to prevent the escape of dust or blast media into the work environment.
The rotary table of the SPRXS-900 is suspended from the roof of the blast cabinet, with twelve rotary spindles mounted around the perimeter of the table. One unfinished part is hung below each spindle on a hook, a mode of component handling that normally does not mask the part-holding area or interfere with complete coverage. The table's precise cam indexer jogs to ease loading of parts through the full width front door.
When the door is closed and the automated process cycle is initiated, the spindles at two active blast stations rotate at controlled and adjustable speed as the components are exposed to blast from multiple pre-arranged nozzles. Vertical oscillation of the blast guns enables even finishing of all aspects of the components with a minimum number of nozzles, and it's stroke and frequency can be simply adjusted to accommodate parts of different lengths and diameters. After the rotary table has indexed to present each component for the programmed blast treatment, completion of the batch is signaled to summon the attendant for reloading.
Available with suction-blast or direct pressure media delivery, the SPRXS-900 can utilize any type of blasting material, including harsh mineral abrasives such as aluminum oxide grit for etching and profiling, as well as mild engineered materials like resilient plastic beads for deburring and deflashing work. The finishing enclosure can be optionally equipped with a rotary basket for tumble-blast treatment of small components.
The overall dimensions of the automated blast cabinet are 90" H x 52" W x 51" D. A touch-screen panel streamlines the system control interface, provides text prompts or instructions and simplifies entry of processing data to be stored in the machine's programmable logic controller (PLC). The blast system manufacturer offers an extensive list of sensor and fault indicator options that are claimed to help eliminate potential sources of process variation and reduce the demands on the human operators.
Prospective users of the Model SPRXS-900 or other manual or automated blast systems are encouraged to submit sample components for free testing in the application engineering laboratory at Guyson's Saratoga Springs, New York, factory.
