Abstract

An improved tool includes a milling tool rotatable about an axis, and a coaxially mounted grinding wheel positioned slightly axially towards a workpiece from the milling tool. The milling tool provides rough finish on a workpiece, and the grinding tool follows, providing finish grinding. The present invention recognizes that the grinding tool will be deflected away from the workpiece at high speed due to centrifugal forces. The present invention positions the milling tool relative to the grinding wheel at a location that compensates for the expected deflection of the grinding wheel, and achieves the desired amount of grinding.
In further features of this invention, the phenomena of deflection of the grinding wheel due to increased speed is utilized to compensate for wear on the milling tool.
