A lens polishing machine is provided with a carriage which supports a tool carrying yoke for operative oscillation relative to a mounted lens. The yoke has a crank arm with a protruding crank pin which engages a slot wall in a pivotally mounted, slotted elongated link. An elongated, horizontally slidable member, connected to the yoke crank arm and having a longitudinally adjustable pin positioned within the link slot, simultaneously rotates and translates the yoke relative to the lens. The pin is longitudinally adjusted to grind a predetermined contour in the mounted lens. Author
