Abstract

PURPOSE:To enable both shaft holes casted at both ends of a connecting rod or the like to be efficiently worked at one time of centering by a double spindle machine tool. CONSTITUTION:A workpiece A is mounted on a jig 16, and centering means 23a, 23b of centering devices 20a, 20b are lowered to be inserted into casted holes of the workpiece for centering. The workpiece A is fixed by clamp devices 30a, 30b and then the centering means 23a, 23b are lifted to the original position. The movement range of the workpiece A is determined by stoppers 13a, 13b adjusted by the operation of a cylinder 12. When a table 11 is shifted to the right position shown by the chain line, the right side hole is worked and then the left side hole worked when the table 11 is shifted to the left side.
