Abstract: An abrasive jet blasting machine for a continuous abrasive jet blasting treatment of wire-shaped and rod-shaped workpieces includes a plurality of centrifugal wheel units arranged angularly offset relative to each other. To each centrifugal wheel unit are assigned two jet conducting and guiding plates which are adjustable relative to each other. All jet guiding plates are adjustable jointly either toward or away from the workpiece by means of an adjusting device which includes a swivelable lever. The adjusting device includes a sensing device which is directed toward the workpiece and is adjustable in the same sense as the jet guiding plates. The sensing device is in operative connection with an adjusting drive which acts on the lever of the adjusting device.
