Abstract
An apparatus is described for machining a conical ring, particularly a friction ring, which has inside and outside conical machinable surfaces having parallel radially aligned generatrices, which apparatus comprises two coaxial machining tools which consist of an outer tool having an inside conical machining surface for machining the outside machinable surface of said ring and an inner tool having an outside conical machining surface for machining said inside machinable surface of said ring, which machining tools are mounted to be rotatable about a common axis relative to said ring and said ring is adapted to be held between said tools so as to be centered on said axis. The tools are mounted to be axially movable relative to each other to a range of positions in which said outside concial machinable surface of said ring is adapted to be in sliding contact with said inside conical machining surface of said outer tool and said outside conical machinable surface is adapted to be in sliding contact with said inside conical machining surface of said outer tool and said outside conical machinable surface is adapted to be in sliding contact with said inside conical machining surface of said outer tool at the same time and said tools are axially movable toward each other to a predetermined position, which is defined by stop means.
