ABSTRACT:
Apparatus for etching a metal surface utilizes a specially shrouded centrifugal throwing wheel to effect a uniform, non-pulsating application of very fine, lightweight, impact blasting media. The resulting etched finish is of a fine-grained quality suitable for use in lithography. A replaceable, wear-resistant liner is provided within the shroud.
