A gear hobbing machine having a gear train interconnecting a hob and a workpiece to be machined by the hob, the gear train being disconnectable to permit of cutting a stationary workpiece by a milling cutter substituted for the hob, a subsidiary motor operable to impart an increment of indexing rotation to the workpiece between successive cutting operations of the milling cutter, an index plate geared to a table supporting the workpiece and arranged when the milling cutter is in operation to perform a predetermined integral number of revolutions for each indexing movement of the workpiece, a bolt which is engageable with the index plate to lock the table against rotation, and a counter for counting the rotations made by the index plate when the bolt is withdrawn and causing arrest of the index plate and re-engagement of the bolt after the predetermined number of revolutions of the index plate have been performed. |
