Abstract

PURPOSE: To provide the subject nozzle wherein sand is supplied from a tapered part connected to one end of the drum part of the nozzle and diameter-enlarged outwardly, and a tube to be ground is connected to a dummy tube fitted and inserted in the inner diameter enlarged part at the other end of the nozzle drum part, thereby to subject the full part of the tube to be ground uniformly to a grinding operation.
CONSTITUTION: The drum part a of a nozzle is formed into a inner diameter substantially the same as the inner diameter of a tube to be ground, and a tapered part b diameter enlarged outwardly is connected to one end of the drum part a. Then, an inner diameter enlarged part c is connected to the other end of said drum part, and a rubber hose or the like for supplying sand to said tapered part b by compressed air is connected to said tapered part b, a dummy tube 11 having an inner diameter the same as that of the tube 2 to be ground being inserted in said diameter enlarged part c, the tube 2 to be ground being connected to the dummy tube 11, and sand which has been introduced from said tapered part being supplied into the tube 2 to be ground by way of the dummy tube 11, thereby to subject the inner surface of the tube 2 to be ground to the grinding operation uniformly in the whole length.
