Abstract
A method of grinding an annular workpiece having an inner peripheral surface and an outer peripheral surface at least one of which is centered on a workpiece axis comprises the steps of holding the workpiece in a chuck rotatable about the axis and rotating the chuck and workpiece about the axis. A grinding tool is pressed radially against the one surface to remove material from the one surface and a cutting liquid is fed to the one surface to form thereon a liquid layer. A plurality of measuring shoes supported at angularly equispaced locations about the axis are urged radially toward the one surface. A jet of liquid is projected from each of the shoes against the one surface that forms a layer supporting the shoes on the one surface and merges with the layer of cutting liquid.
