Abstract

An apparatus for finishing a surface of a camshaft extending along an axis with the surface offset from the axis has a drive for rotating the camshaft about the axis, a support displaceable radially of the axis, and a plurality of pusher heads on the support. The heads are movable independently of each other toward and away from the camshaft relative to the support along respective angularly offset pusher axes extending radially of the camshaft. All the pusher heads are biased along the respective pusher axes toward the camshaft axis with substantially the same force.
