CERAMIC BLASTING APPARATUS AND METHOD TO PREVENT GEAR PITTING

摘要

An improved method for media blasting a workpiece (20) is described. The media blasting method of the present invention includes the steps of positioning the work piece (20) in a part holder (130) for maintaining the workpiece in at least one predetermined position during a blasting operation; supplying positive air pressure to deliver ceramic media to a blast nozzle (155); directing the ceramic media at the workpiece through the blast nozzle (155); exposing multiple surfaces of the workpiece to the ceramic media; and collecting the ceramic media for reuse in subsequent blasting operation.
