This is for ease of use when indexing plates are available.

Index plates with up to 400 holes are available.

It used a toothed index plate and a worm gear to advance the mechanism.

Brown and Sharpe indexing heads include a set of 3 indexing plates.

The advantage of the direct indexing plate is that it is fast and simple and no calculations are required to use it.

A circular metal plate with even spaced holes around the periphery, mounted to the spindle, is called an "index plate".

Interchangeable indexing plates are used when the work must be rotated to an angle not available on the direct indexing 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.

Direct indexing plate: Most dividing heads have an indexing plate permanently attached to the spindle.

A pin in the base of the dividing head can be extended into the direct indexing plate to lock the head quickly into one of these angles.

This is simpler than setting up a manual indexing head because there is no need to interchange indexing plates or to calculate which hole positions to use.

The number of flutes cut on a shape is dependent on its diameter and the width of the cutter, and the number of indexing plates available.

Vinco Corporation was a Detroit, Michigan based manufacturer of jig (tool)s, fixtures, gauges, gears, ground tools, index plates, and angle tangents.

A lathe equipped with indexing plates, profile cutters, spiral or helical guides, etc., so as to enable ornamental turning is an ornamental lathe.

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.

CNC indexing heads are similar in design to the manual variety except that they have a servo motor coupled to the spindle instead of a hand crank and indexing plates.

It is also faster for repetitive operations because the work can be indexed by simply pressing a button, eliminating the need to count rotations of the hand crank or specific hole positions on the indexing plate.

If the indexing worm is not disengaged from the table, one can move the table in a highly controlled fashion via the indexing plate to produce linear movement of great precision (such as a vernier scale).

Rogers's original telegraph instrument for the train replaced the traditional sending key and sound receiver with a dial indicator, a circular index plate bearing the letters of the alphabet and a pointer that turned to the letter to be transmitted.

Some rotary tables allow the use of index plates for indexing operations, and some can also be fitted with dividing plates that enable regular work positioning at divisions for which indexing plates are not available.
