Three additional indexing plates included to provide the ability of indirect dividing of all divisions from 2 to 50 and also most common divisions up to 380. • Hardened Simple index includes 3-jaw chuck, masking plates 2, 3, 4, 6, 8 a

The worm wheel usually carries 40 teeth, with the worm is single-threaded. The two following examples show how the index plate is used to obtain any desired part of a whole spindle turn and, consequently, the work by simple indexing: (a) First example: To mill a hexagon. Procedure: Using the rule previously given, divide 40 by 6, which equals 6-1/2 turns, or six full turns plus 2/3 of a turn on any circle whose number of holes is divisible by 3. The index plate has 24 holes and the periphery of job can be divided into 2, 3, 4, 6, 8 and 12 equal parts directly. This type indexing is most commonly used for indexing fixture. 2. Simple or Plain Indexing: In this case, different index plates with varying number of holes are used to increase the range of indexing.

So, for the example of a rocket tube with 4 fins, indexing and marking through the numbers 0, 15, 30, and 45 gives the correct points. Here's a method I figured out on how to index a work piece on a lathe for marking out degrees or divisions. This is very useful for marking 3, 4 or more hole 2012-10-09 · Today, lets talk about indexing, a technique used to compare changes in values over time. What is indexing?

## Clarification: Indexing ratio = (number of slots on index plate)/ (number of division required). Hence indexing ratio is equal to 3. 5. Circumference of a work piece is to be divided into 60 equal divisions using simple indexing method having 40 worm wheel teeth. Indexing movement will be a) 12 holes on 18 hole circle b) 16 holes on 18 hole

Indexing movement will be a) 12 holes on 18 hole circle b) 16 holes on 18 hole Simple Indexing Calculating the indexing or number of turns of crank for most, simply divide 40 by number of divisions or flats to be cut. Meaning: 19 Turns of the crank = 40 No of flats needed Indexing (Dividing) Head.

Half of that, or a resolution of 2.5 minutes of arc, is easily guesstimated by positioning the index pin midway between the index holes. of divisions can be made by dividing this dimension by the number of divisions required. The calculated linear dimension for one complete revolution is 4.712 inches (119.685 mm), but this dimension may vary slightly from one indexing attachment to the next.
