High precision grinding and remanufacturing of machine components

A process for grinding elongate machine components comprising:

• engaging a chuck of a grinding apparatus with an elongate machine component, including seating one end of the machine component in the chuck and clamping the chuck about the one end;
• contacting a rolling element of a steady rest of the grinding apparatus with the machine component at a contact location subsequent to the engaging of the chuck, the machine component defining a first axis and the grinding apparatus defining a second axis;
• grinding a first and a second surface on an outer diameter of the machine component each positioned between the one end and the contact location, while contacting the rolling element with the machine component at the contact location, and such that the machine component is rotatably supported by the rolling element and rotates relative to the steady rest;
• and
• prior to grinding the first and second surfaces, establishing congruity between the first axis and the second axis by rotating the machine component while contacted with the rolling element at the contact location, and such that the machine component is rotatably supported by the rolling element and rotates relative to the steady rest, then reseating the one end of the machine component in the chuck.
