Abstract:  
A cleaning and treating apparatus which employs a series of nozzles or guns for propelling abrasives into interior and exterior exposed surfaces of components. The forces required to propel the abrasive materials are provided by fluid pressure supply sources which can be adjusted separately to deliver a wide range of high and low pressures to each individual nozzle outlet. Having available these variably selectable fluid pressure sources at each individual nozzle, combined with means for directing each nozzle relative to the machined component being cleaned or treated, enables this apparatus to perform its intended function without distorting the surfaces upon which the work is being performed. Furthermore, it allows an operator of the unique apparatus to correct any existing surface disconfigurations or otherwise control the shape of the component as desired.
