Patent ID: 8474140

Claim:
A method of remanufacturing an elongate valve component of a hydraulically actuated device comprising: receiving an elongate valve component removed from service in a hydraulically actuated device; setting up a grinding apparatus for regrinding the valve component, including seating one end of the valve component in a chuck of the grinding apparatus and clamping the chuck about the one end, then contacting a rolling element of a steady rest of the grinding apparatus with the valve component at a contact location while rotating the valve component in the chuck, such that the valve component is rotatably supported by the rolling element and rotates relative to the steady rest, and then reseating the one end of the valve component in the chuck; and subsequent to setting up the grinding apparatus for regrinding the valve component, regrinding a first surface and then a second surface of the valve component each positioned between the one end and the contact location, while contacting the rolling element with the valve component at the contact location, and such that the valve component is rotatably supported by the rolling element and rotates relative to the steady rest.
