Abstract
A rotatable workpiece holder for holding a hollow cylindrical workpiece thereon functions as a chiller for cooling the hollow cylindrical workpiece. A coolant, e.g., water, is supplied to the hollow cylindrical workpiece through second coolant passages and branch passageways defined in the workpiece holder, thereby cooling the hollow cylindrical workpiece. The coolant forms a film in a clearance between the outer surface of an annular side wall of the workpiece holder and the inner circumferential surface of the hollow cylindrical workpiece.
