Abstract: A torque-resistant dual face seal includes a seal ring having an L-shaped cross-section including an axially-extending flange and a radially-extending flange, the seal ring including an annular seal face and an opposing loading surface. The seal ring includes a plurality of deformations formed in a spaced apart arrangement circumferentially around the axially-extending flange. An axial cross-section through the axially-extending flange and intersecting one of the plurality of deformations includes a stepped geometry. The plurality of deformations allows a load ring to squeeze into the plurality of deformations to increase a surface area contact between the seal ring and the load ring.

Abstract: A machining center with an abrasive blasting system is disclosed. The machining center includes a bed, a headstock mounted on the bed, and a carriage having a tool post. The machining center also includes an abrasive blasting system for imparting a predefined roughness to a surface of the work piece. The abrasive blasting system includes a reservoir, a pump, a tool and a nozzle. The tool is coupled to a tool post. The tool includes a conduit extending along a length of the tool for receiving the abrasive material therethrough. The nozzle is formed on a tip surface of the tool. The nozzle is configured to communicate to the conduit. The nozzle is adapted to discharge the abrasive material on the surface of the work piece during the machining of the work piece for imparting the predefined roughness on the surface.
