ABSTRACT:
A process for producing ceramic products such as turbine rotors comprises the steps of contouring a prefired ceramic roughly or primarily formed workpiece into a desired shape by means of a rod-shaped cutting tool having a working end or tip to which abrasive particles have been secured, said tool being rotated about its axis; subjecting the contoured surface of said workpiece to an abrasive finishing; and thereafter firing said workpiece thus finished.
