Concept: Simple indexing mechanism. A simple indexing mechanism consists of a 40 tooth worm wheel fastened to the index head spindle, a singlecut worm, a crank for turning the worm shaft, and an index plate and sector. Since there are 40 teeth in the worm wheel, one turn of the index crank causes the worm, and consequently, the index head spindle to make 1/40 of a turn; so 40 turns of the ...

An end mill is a type of cutting tool that is used in milling applications. It is a rotating tool that is used to remove material from a workpiece. End mills are usually made of highspeed steel (HSS) or carbide and come in a variety of shapes and sizes. They are available in solid and indexable milling styles.

End milling is facilitated by cuts done in several directions, in contrast to the axial directional cutting that is typical of drill bits. End mills can be categorized based on the sort of tools that are affixed to them, number of flutes, helix angle, compositional material and even coating material. Specifications can vary depending on the ...

In melt spinning, polymer is heated and it melts to form a liquid spinning solution or dope. Chips of polymers are fed to a hopper which is heated. There is a grid (sieve) at the base which permits only molten liquid to pass through. Then the solution is purified by filter. The molten polymer is extruded at high pressure and constant rate through a spinneret into a relatively cooler ...
