<p>Abrasive and a fluid are mixed and supplied from a container to a first part of a workpiece to be cleaned and then returned to the container means. The abrasive cleaning is accomplished by reversing the flow of the fluid and abrasive mixture to direct the mixture to a second part of the workpiece and the cleaning is also effected by utilizing the mixture of air and a liquid as the fluid carrier of the abrasive. This mixture is used to clean metal castings or to debur machined metal parts. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.</p> |
