ABSTRACT:
An ancillary device with at least one rotating workpiece holder for removing abrasive from externally accessible cavities inside such large workpiece as engine blocks, transmission housings, etc. once they have been sand blasted in a centrifugal-jet system. The device has a shaft (4) that has the workpiece holder (3) extending out of its outer end and that rotates along with the workpiece holder about a single horizontal axis. The device also has a rotary drive mechanism (7) that has a horizontal axis of rotation. The inner end of the shaft is secured to the drive mechanism by way of a transmission, causing the shaft to rotate or pivot about its axis. The device can also have at least two shafts (4 & 5) with workpiece holders (3 & 6) mounted symmetrically on the rotary drive mechanism.
