If a vertical milling machine is being used then the same cutter is used but it is mounted on a stub arbor. This is then fitted to the vertical head. Cutting a spur gear using the horizontal arbor – 708. Use of spur gears. Spur gears can be use to transfer power. In doing this they can also be used to shift the axis from where the power comes from to any other axis parallel to the first

A simple indexing mechanism consists of a 40tooth worm wheel fastened to the index head spindle, a singlecut worm, a crank for turning the wormshaft, and an index plate and sector. Since there are 40 teeth in the worm wheel, one turn of the index crank causes the worm, and consequently, the index head spindle to make 1/40 of a turn; so 40 turns of the index crank revolve the spindle one full
