Abstract

PURPOSE: To remove fins through simple operation with a simple device by press ing a tapered punch into a casting hole in removing the flash of the casting hole.
CONSTITUTION: Fins 3 projecting in the axial line direction of the casting hole 2 of a casting 1 from the edge of said hole are produced. A punch 4 is pressed coaxially to the casting 1 in the axial line direction of the hole 2. If this pressing force is made larger than the shearing force of the fins 3, the leading end part 5 of the punch 4 shears and removes the fins 3 from the root while flaring the fins forcibly as the punch advances. Thereby, trimming is accomplished by the simple operation of just pressing the tapered punch 4 to the axial line direction of the hole 2.
