ABSTRACT:
A tapping machine of the type in which the workpiece is automatically positioned, has a releasable connection of the worktable and carriage with the means for horizontally moving the worktable and the means for horizontally moving the carriage, so that the worktable and carriage may be released for manual operation. The tapping machine also has a means for detecting the position of the carriage and a means for detecting excessive thrust from the workpiece. In addition, the tapping machine may be provided with means for detecting the position of the worktable and a control device having a memory connected with the means for positioning the worktable so that when the worktable is manually positioned, the manual position may be entered and recorded in the memory of the control device. The tapping machine may thus be programmed so that multi-variety, small volume tapping is efficiently performed.
