Abstract

The invention relates to fluid jet polishing machine including a pump that maintains a constant pressure in the polishing fluid during each pass of a nozzle over a component. Fluid actuated diaphragms expand and contract the volume of a pair of pump chambers, thereby eliminating the need for high-speed shafts or components in contact with the abrasive slurry.
