Guyson Corporation manufactures a series of work-cell-sized automated blasting machines for surface finishing, shot peening, precision roughening and other media-blast applications. One of the most popular models of this type is the RXS-400 indexing spindle-blast system, now available with pressure-blast media delivery and a lance nozzle for treating the inside diameter of hollow components.
The 34 x 36-inch blast cabinet has automatic vertical sliding doors at the front loading station and a hinged access door on one side to facilitate inspection, adjustment and maintenance. Two shielded ball bearing spindles are mounted on a180-degree indexing turntable allowing components to be unloaded and loaded during the blasting cycle. The cam indexer of the RXS-400 is sufficiently accurate to allow automated loading by a machine-tending robot or pick-and-place device.
Inside the blast chamber, the fixtured component is rotated at controlled and adjustable speed as target surfaces are exposed to the timed blast from one or more blast guns. In the lance blasting version, a single angled blast nozzle is rigidly bracketed in position on a ball screw / ball nut linear actuator, so the programmable stroke and speed of the lance nozzle can be synchronized with component rotation.
Configured for ceramic shot peening of precision-bore industrial machine parts, the RXS-400 is equipped with a media reclamation system enhanced by a vibratory screen classifier to feed only shot of the specified size to the pressure pot.
The Allen-Bradley programmable logic controller (PLC) coordinates all functions of the rotary spindle blast machine and is capable of storing and recalling blast process recipes for many different components. In addition to dimensional data for a variety of parts, such as bore diameter and component length, from which the traversing motion of the nozzle and rotation rate based on surface speed are derived, the programmed recipe can include the blast pressure, the duration of the blast and blow-off air wash cycles and verification of shot flow.
Larger and smaller standard models of rotary indexing spindle-blast machines are available from Guyson Corporation to meet the production and finish requirements of each individual customer.
Prospective users of automated or robotic blasting equipment are encouraged to submit sample components for free laboratory testing and application engineering evaluation at the Guyson factory in northeasternNew YorkState.
