Abstract

PURPOSE: To pressure-mold the bore surface of the casting immediate after solidification and improve the productivity and yield of various kinds of centrifugal castings by puring molten metal into a centrifugal casting mold then inserting a pressing member into the hollow part thereof.
CONSTITUTION: After molten metal is injected into a centrifugally casting mold 1 in order to cast a casting 2, a pressing head 6 is inserted into the hollow part of the casting 2. Next, the pressure molding operation of the inside surface is performed by the pressing head 6 while the casting is hot right after solidification. More specifically, the roller 7 of the pressing head 6 is pressure-contacted to the bore surface of the casting 2 and is reciprocatively moved in the axial direction of the casting 2 whereby the bore surface is evenly pressure-molded and at the same time the bore surface is smoothed by the cutting tool 8 at the end of the pressing head 6 prior to pressing of the roller 7.
