741. Mar 18, 2015. #1. I recently saw where someone needed to cut a 63 tooth gear but his dividing head (40:1) didn't have a plate with 63 holes. His rotary table (90:1) did have a 63 hole circle on a plate. I'm just wondering why plates for a 40:1 dividing head don't seem to have a 127 hole pattern or in this person's case a 63 hole pattern.
As the milling machine dividing disc with holes limited, some of the division number because there is no suitable hole ring, and can not be simple dividing method, such as 73, 83, 113 and so on.
Indexing (Dividing) Head • Once one of the more important attachments for milling machine • Used to divide circumference of workpiece into equally spaced divisions when milling gear teeth, squares, hexagons, and octagons • Also used to rotate workpiece at predetermined ratio to table feed rate 2. 3.
: a table-milling machine equipped with all the movements and a dividing head with spare wheels to be able to carry out any type of milling operation. How are partial heads calculated? The first thing you need to do is calculate the number of decimal places for the distance between the slots, which is 360 degrees divided into 7 divisions.
Install the Dividing Plate 1. Slide the dividing plate onto the shaft. 2. Secure it with two socket head cap screws. 3. Place the flat spring in the groove in the dividing plate hub. 4. Put the two sector arms on the dividing plate. 5. Install the retaining nut. 6. Install the crank handle. 7. Reinstall the washer and nut on the end of the shaft.
Depends on the stuff you do, but I have both and use the dividing head about 5-10X the amount I use the rotary table. The dividing head can be rotated vertical and the lathe chuck attached, with the lathe work still in it. IMO, the rotary table is always a pain to set up, locate center, then somehow clamp the work where you need it.

When used as a plain dividing head the dividing plate is locked in position. When used for helical milling the dividing plate is unlocked and can be turned by means of the auxiliary input. Dividing heads that swivel in the horizontal plane. These are very unusual. It would seem that the one thing they can do conveniently is making bevel gears.
A dividing head is indispensable for machining gears on a milling machine, and, when used in conjunction with a universal milling machine (swiveling table), helical gears can be readily machined. In addition, the dividing head makes it possible to easily yet accurately produce special cutting tools.

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.

The mandrel is then mounted between the centre of the dividing head. A form relieved shaped profile fluting cutter (right-hand) is mounted on the arbor with its largest diameter opposite the spindle (Fig. 16.69). In this way the profile cutter will mill the flute by the conventional or up milling method.
A dividing head, or indexing head, is a machine tool attachment that allows a work piece to be rotated in precise, pre-determined increments for machining of repeated profiles. A dividing head is generally used as an accessory on milling machines to machine any product consisting of several equal radial facets.
