Symmetrical mill

摘要

An apparatus and method for in-situ milling includes a support and a pair of spaced apart rails attached to the support. The support and rails are mounted between a pair of opposed mill housing wear plate surfaces. A milling assembly is reversibly mounted on the rails in either of a first orientation and a second orientation. In the first orientation, the milling assembly mills one of the wear plate surfaces. The milling assembly is reverse mounted on the rails to the second orientation for milling the other of the wear plate surfaces. This permits the support and the rails to remain in one position between the wear plate surfaces requiring only the milling assembly to be moved to accomplish milling of each of the wear plate surfaces.
