What is a dividing head?

The dividing head or indexing head is an attachment of the machine that allows the work piece to be rotated in accurate, predetermined additions to machining repeated profiles. For example, if a part of the round steel rod needs a hexagonal profile machined to one end, a dividing head could be used to rotate the rod in precise steps to make the machine on the machine for the machine for the machine. Usually, rotation or promotion of the dividing head is achieved manually using a crank handle equipped with a locking pin that locks the head to the position for each machining cycle. The dividing heads can also be tilted by 90 degrees along their own axis to ensure flexibility during adjustment. The dividing head is generally used as accessories on milling machines to the machine for any product consisting of several same radial aspects.

Use of milling machines to cut geometrically accurate,Multiple -sided professionals require a work piece to be advanced or rotated in very accurate steps for each cut. The dividing head achieves this accurate rotation by using a disk mounted on a spindle with concentric rows of equidist holes drilled through it. The crank handle equipped with a spring blocked pin and then changes the spindle the desired distance, whereupon the locking pin is inserted through one of the holes to lock the spindle in the position. When the cut is complete, the pin is pulled out and the spindle turns with the same number of holes and locked with a pin. This allows the working piece to turn exactly the same distance.

Since the disk or index plate has several rows of holes, a large range of different rotary distances can be achieved. Each concentric ring or line will have fewer holes located on different spacing as soon as the lines approach the center of the disk. The indexing board will generally be equipped with six rows of holes and are often purchased in sets of threeEch boards, each with different holes of the hole. A typical set of indexing plates will contain openings numbers ranging from 15 to 49 holes per row, giving a wide range of incremental flexibility.

Division accessories are used on milling machines for production as much as objects such as reamers, gears, pieces of machine tools and geometric arms used to receive handles and power bars. The dividing head assembly can be used in an orientation of a straight axis or tilted over 90 degrees for additional machining flexibility. Most of the dividing heads are indexed manually, although larger units can be fully automated.
