General.
Indexing equipment is used to hold the workpiece, and to
provide a means of turning it so that a number of accurately located speed
cuts can be made, such as those required in cutting tooth spaces on gears,
milling grooves in reamers and taps, and forming teeth on milling cutters.
The workpiece is held in a chuck, attached to a indexing head spindle, or
mounted in between a live center in the indexing head and dead center in the
footstock. The center rest can be used to support long slender work. The
center of the footstock can be raised or lowered for setting up tapered
workpieces that require machining.
