Sometimes a number of divisions are required. which cannot be obtained by simple indexing with the index plates regularly. supplied. To obtain these divisions a differential index head is used. turn that you should rotate the index crank. For example, the calculation. for determining 15 An indexing head, also known as a dividing head or spiral head, is a specialized tool that allows a workpiece to be circularly indexed; that is, easily and precisely rotated to preset angles or circular divisions.Indexing heads are usually used on the tables of milling machines, but may be used on many other machine tools including drill presses, grinders, and boring machines. index. Basically you can read off the angle on a scale, the scale can uses an indexing plate rather than a dial with angles on it. You need to make the calculation of how many turns and parts of a turn are made for the number of flats or positions you need. 5. Dividing Head One of the more important attachments for milling machine. •Used Index plate hole calculator. This is an online calculator to calculate what indexing plate to use and number of holes to skip for a given number of divisions. This calculator can be used for both rotary tables and indexing heads. The ratio below describes how many turns of the handle makes the table rotate one full revolution.

Using Dividing Plates with the Rotary Table Dividing plates allow you to precisely divide a circle into a number of divisions or degrees. The indexing feature helps prevent errors during the repetitive adjustments required in indexing work. Dividing plates can be used to create bolt circles, gears, polygons, and so on.

## Through gearing, the index plate and worm A can be driven together from the table feed screw when the index pin is in position in any hole of the pla. When worm A is turned by means of the index crank, indexing may be accomplished, and when it is geared to the table feed screw, spiral milling, in addition to indexing, is made possible.
