Indexing in Milling Indexing is an operation of dividing a periphery of a cylindrical workpiece into equal number of divisions by the help of index crank and index plate. Because the operator of the machine may want to rotate the part to an arbitrary angle indexing plates are used to ensure the part is accurately positioned.
Just as I did for my Sebastian treadle lathe, rather than making any permanent, irreversible changes to the Atlas milling machine's plain indexing centers, I made an adapter to enable use of the South Bend lathe's change gears (which mostly have a 9/16ths inch bore) as templates. The adapter consists of a plug closely fit to the bore of the indexing center's spindle and …

Index milling refers to a special kind of milling operation wherein the machine is set to perform identical operations on a work piece. Each of these identical operations is performed one after the other by indexing the work piece into a new position. A very good example of such a process is the gear cutting operation wherein the gear grooves ...
The operation of rotating the job through a required angle between two successive cuts is termed as indexing. This is accomplished with the help of a milling attachment known as dividing head, which is an accessory to the milling machine. It helps to divide the job periphery into a number of equal divisions, i.e., square, hexagonal octagonal, etc.

Universal index head is the name applied to an index head designed to permit power drive of the spindle so that helixes may be cut on the milling machine. Gear cutting attachment is another name applied to an indexing fixture; in this case, one that is primarily intended for cutting gears on the milling machine.
The indexing head doesn't only look great, but allow you to do more with your milling machine: measuring specific angles and dividing a circle into equidistant arcs. It comes with 3 interchangeable indexing plates and a tailstock to ensure more precise and stable work.
