This indexing rotary spindle blast system facilitates overall descaling, surface preparation and cosmetic finishing of components. The Model SPRXS-900 individually processes a dozen components per load.

The rotary table is suspended from the roof of the blast cabinet, with 12 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 processing 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 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 system can use any type of blasting material, including harsh mineral abrasives such as aluminum oxide grit for etching and profiling, as well as mild engineered materials. The finishing enclosure can be optionally equipped with a rotary basket for tumble-blast treatment of small components.
