ABSTRACT:
Successively supplied rod materials with one or more flat surfaces such as tuning pins used for pianos are intermittently and periodically forwarded in axial alignment to each other along a prescribed guide path towards a drilling station with axial postures thereof being regulated through rolling and, when required, sliding contacts with machine parts and, drilled transversely preferably by a pair of drills from two opposite sides with difference in timing and stroke without development of metal refuses and, after the drilling operations, the results in the drilling operation are preferably inspected in mechanical or photoelectrical manner in order to stop the entire machine running when any failure in the drilling operation is detected, all the recited operations being carried out fully automatically.
