<p>Abrasive jet stream polishing, wherein an abrasive is suspended in a flowable jet medium (24) and projected at high velocity and pressure at a workpiece (12), where the jet is projected at the surface to be polished at an oblique angle. The method is substantially improved by forming the medium of a polymer having reformable sacrificial chemical bonds which are preferentially broken under high shear conditions. Projecting the medium and suspended abrasive breaks the reformable sacrificial chemical bonds while polishing. The chemical bonds will reform permitting recycling (80, 82, 84) of the medium and abrasive for reuse in the method. The jet is effective at relatively low pressures of about 5 to about 80 MPa.</p> |
