Patent ID: 7335091

Claim:
A machine assembly for use in machining a coupling, said machine assembly comprising: a machine tool; at least one grinding wheel comprising: a body comprising a first end, a second end, a chamber defined therebetween; at least one grinding surface extending outwardly from said body second end and defining an end face of said grinding wheel; and a cooling system extending through at least one of said body and said at least one grinding surface for supplying coolant from said chamber to said at least one grinding surface through a plurality of openings defined inward of said at least one grinding surface; a tool storage member coupled to said machine tool, said at least one grinding wheel removably coupled to said tool storage member, said machine tool configured to use said at least one grinding wheel to machine a plurality of troughs in at least one generally annular coupling member such that at least one projection is defined between adjacent troughs, wherein the coupling member is configured to be rotationally coupled to another coupling member using the projections and troughs; and a tool changer configured to move said at least one grinding wheel between said tool storage member and said machine tool.
