Oct 21, 2013 . Using a dividing head and a vertical milling machine to cut flats on a shaft. Simple indexing method is used.
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.
Indexing of Milling Machines Indexing is the process of evenly dividing the circumference of a circular work piece into equally spaced divisions. It is used in cutting gear teeth, cutting splines, milling grooves in reamers and taps, and spacing holes on a circle.
These processes involve separating the different fractions of hydrocarbon compounds that make up crude oil base on their boiling point differences. ... industry, which came into force in 1971, did not limit the total amount of pollution, but rather permitted the discharge of pollutants in proportion to the production of the mill.

Non-traditional Machining Processes. Manufacturing processes can be broadly divided into two groups: primary manufacturing processes : Provide basic shape and size; secondary manufacturing processes : Provide final shape and size with tighter control on dimension, surface characteristics. Material removal processes.

In form milling, indexing of the gear blank is required to cut all the teeth. Indexing is the process of evenly dividing the circumference of a gear blank into equally spaced divisions. The index head of the indexing fixture is used for this purpose. The index fixture consists of an index head (also dividing head, gear cutting.

Cold grinding .. For both hot and cold applications, rolls can be divided into two different families: Work rolls and Back-Up rolls.
Differential indexing has to be employed when the number of divisions to be achieved is not possible by simple indexing. You have learnt about simple indexing in the first year. It was employed to divide the circumference into equiangular divisions. The angular movement required was carried out on the indexing head.
The milling cutter is mounted on a spindle which rotates on roller bearings. The combined table unit fitted with cross slide, saddle and table unit is swivellable and travers through a rack & pinion for easy movement. The cross feed movement is graduated in 0.001" division for fine grading and swivel base LH and RH cutters.
