Abstract: Grinding a machine component such as a valve component during remanufacturing, includes seating one end of the valve component in a chuck of the grinding apparatus, then contacting a steady rest with a reference surface on an outer diameter of the valve component while rotating the valve component, and then reseating the one end of the valve component in the chuck. A first valve surface on an outer diameter of the valve component is ground while contacting the steady rest with the reference surface, then a second, different valve surface on the outer diameter of the valve component is ground also while contacting the steady rest with the reference surface. The valve component is then reassembled with a hydraulically actuated device for service therein.
