1. A multi-tool positioning and manufacturing system comprising:
a top plate;
a workhead to support a workpiece in a plane parallel to the top plate;
a first spindle, fixed with respect to the top plate, to spin a first grinding wheel about a first axis parallel to the top plate;
a second spindle, fixed with respect to the top plate, to spin a second grinding wheel about a second axis parallel to the top plate; and
an eccentric positioning system, supporting the workhead, to move the workhead and the workpiece with three degrees of freedom in the plane parallel to the top plate from the first grinding wheel to the second grinding wheel, the three degrees of freedom including two linear degrees of freedom and one rotational degree of freedom in the plane parallel to the top plate.
