Abstract

PURPOSE: To easily and surely remove a residual object even after burring work, by supplying freezing material to the inside of a hollow member, and then applying pressure from one side of the hollow member, breaking a burr while deforming further circulating the freezing material and discharging the burr to the outside.
CONSTITUTION: In the surroundings of small holes 3, 4, there are formed burrs 5, 6 protruding toward a hollowed part. To remove these burrs 5, 6, the small holes 3, 4 are closed by using gum tapes 7, 8, and then liquid of water or the like is poured into the hollowed part of a cylinder 1 from another opening part 2, lowered its temperature and frozen. Then the gum tapes 7, 8 are removed, and a rod 10 is inserted into the cylinder 1 while applying pressure. As pressurizing force increases a frozen material 9 is discharged from the small holes 3, 4 to the outside, here the burrs 5, 6 are curved around a supporting point in the vicinity of their base part, broken off and discharged to the outside.
