摘要
A perforating apparatus for a cylindrical workpiece, including: a cradle having a groove extending in one direction horizontally from one end to another end; a stopper provided at the one end of the groove; a drill disposed vertically above the groove and movable at least in vertical direction, having a drill bit that extends vertically; and a chuck having a pair of opposing grippers movable toward each other in a horizontal direction perpendicular to the direction in which the groove extends, and symmetrically with respect to a rotation axis of the drill bit, each of the grippers further having a pair of vertically symmetric inclined surfaces expanding upwards and downwards.
