Abstract

<PICT:0962656/C6-C7/1> <PICT:0962656/C6-C7/2> A method of electrolytically and abrasively shaping the internal cylindrical bore surface of a workpiece W, Fig. 3, comprises bringing the surface into contact with a rotating tool 92 having insulating abrasive particles, e.g. of aluminium oxide or diamond bort protruding above the surface of an electrically conductive cylindrical body, making the diameter of the tool only slightly smaller than that of the bore of the workpiece, so rotating both the workpiece and the tool that the surface speed of the tool is substantially greater than that of the workpiece, feeding electrolyte into the interface between the tool and the workpiece and passing direct current at a density of at least 1000 amps/sq. inch between the workpiece and the tool body in a direction to make the workpiece anodic and the tool cathodic. The workpiece and tool are moved generally in the direction of the arrows 110, 112. They may be rotated in opposite directions and the workpiece may be rotated at a low speed for its first revolution and then at a higher speed to finish the shaping. Electrolyte supplied through a bore 68, Fig. 4, in a shaft 30 supporting the workpiece (or through a bore in a shaft supporting the tool, Fig. 5 not shown) floods the working interface and flows from the other end of the workpiece. The tool and workpiece are mounted so that they can be moved over ways 20, 22, 24 at right angles to one another, (Fig. 1 not shown).
