ABSTRACT:
A microfinishing machine particularly adapted for microfinishing external cylindrical surfaces such as found on internal combustion engine crankshaft bearing journal. The machine includes a microfinishing tool assembly which presses an abrasive coated film against the workpiece and a gaging tool assembly which enables in-process diameter measurements to be made. The microfinishing tool assembly features means for shifting the center of pressure exerted on the abrasive coated film along the axial surface of the cylindrical surface being machined. Such adjustment can be achieved by shifting the pivot axis of the tool or by exerting an external torsional load onto the tool. The microfinishing tool assembly according to this invention allows axial form errors such as tapering of journal surfaces to be corrected in the microfinishing operation.
