Abstract: A centerless microfinishing machine especially adapted for machining camshaft workpieces. The microfinishing machine causes the camshaft workpiece to rotate through the use of a centerless drive system including spaced rollers which frictionally engage the workpiece. A tooling head assembly strokes between engage and disengage positions and includes individual shoes which simultaneously engage the camshaft lobe and camshaft bearing journal surfaces. Through the use of separate compliant elements, these tools are caused to follow the contours of the surfaces being machined. The tooling head assembly allows these surfaces to be machined simultaneously; therefore, multiple machine functions can be accomplished in a single manufacturing step, which reduces the number of individual pieces of equipment which are required in accordance with typical machining approaches.
