Abstract
An actuator adapted to adjust the profile of a carrier supporting a bar relative to a lapping surface. The carrier including a plurality of spaced control or actuation points along the length of the carrier for adjusting the profile of the mounting surface of the carrier adapted to support a bar for lapping. The actuator adapted to actuate the carrier at the spaced actuation points and including a plurality of actuation members movably actuated via pressure supplied to the actuation members. The actuation members are supported in spaced staggered relation in chambers in a manifold. The actuation members are spaced relative to the spaced actuation points and are supported relative to the manifold to provide precision actuation for incrementally adjusting the profile of the carrier.
