Abstract
A method of forming a hydrostatic nut that cooperates with a lead screw for translating a wheel head, or carriage, on a grinding machine, such as a cam grinder. A lead screw, which is externally threaded, is inserted into a cylindrical mold, which is internally threaded. The lead screw is retained therein by pressure plates that seal off opposite ends of the open bore of the mold.
