INDEXING HEADS (Dividing Head) An indexing head (also called a dividing head) is a machining tool that allows a workpiece to be rotated, that is, easily and precisely rotated to any angle or circular division. Indexing heads are usually used on the tables of milling machines. The milling of spirals or helical cutting action requires the rotation of the workpiece in a known relation to the traversal of the cutter.
MILLING MACHINE OPERATIONS OD1644 LESSON 1/TASK 1 (8) Differential Indexing. Sometimes a number of divisions are required. which cannot be obtained by simple indexing with the index plates regularly. supplied. To obtain these divisions a differential index head is used. The.
Process of adjusting the vertical milling machine head so that the spindle is perpendicular to the top surface of the machine table. Direct indexing Method of indexing that allows the spindle of the indexing device to be directly rotated by hand and locked with pin or plunger against an indexing plate having the appropriate number of divisions.
Aug 16, 2008· Indexing Indexing is the process of accurately spacing holes, gear teeth or other machined areas on the perimeter or face of a workpiece. There are several variations in the indexing operation such as direct indexing, simple indexing, angular indexing, differential indexing and rotary table indexing.
a. General. The milling machine removes metal with a revolving cutting tool called a milling cutter. With various attachments, milling machines can be used for boring, slotting, circular milling dividing, and drilling. This machine can also be used for cutting keyways, racks and gears and for fluting taps and reamers. b. Types.
Extends the capabilities of drill presses, surface grinders, and milling machines. Vernier reads to 10 minute accuracy, .0005" ground lapped; 2" travel for flute grinding. Simple 1° indexing. Hardened and ground spindle. Index plate has 36 hole circle. Spindle run out within .0005" on Phase II model. Spindle lock and hole for tightening collet.
A simple indexing mechanism consists of a 40-tooth worm wheel fastened to the index head spindle, a single-cut 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 index crank revolve the spindle one full turn.
a fractional part of a turn with index plates. A. Example: Indexing for a hexagon head bolt: commonly used index head comes with three index. because a hexagon head has six flats, plates. Each plate has six circles of holes, which we. will use as an example.
The indexing attachment can be attached directly to the table of the Sherline milling machine, or the indexing head can be used by itself in a horizontal position similar to a rotary table. The indexing attachment is not recommended for use on the Sherline lathe with the vertical milling column; however, with the use of shims to elevate the unit high enough to clear the crosslide handwheel, it can be done.
CE High precision milling machine 1.Features: 1)Rectangular table guide-ways with high stability; 2).Hardened and ground table surface; 3).Automatic feeds on X,Y
Standards ranging from the classic production turning machine to tailor-made machining cells equipped with handling units. For the machining of simple to highly complex parts, in small to large lot sizes, INDEX consistently offers economically and technologically superior solutions.
Indexing heads are usually used on the tables of milling machines, but may be used on many other machine tools including drill presses, grinders, and boring machines. Common jobs for a dividing head include machining the flutes of a milling cutter, cutting the teeth of a gear, milling curved slots, or drilling a bolt hole circle around the circumference of a part.
May 21, 2018· 2. Horizontal Milling Machine. In horizontal milling machine, the spindle axis is aligned horizontally. The base of horizontal milling machine is made up of grey cast iron. In this machine, an arbor is used and it is inserted in spindle nose. The gear arrangement is inside the
In case of head milling machine feed motion is given by hand and movements of the machine are provided by motor. This is simple and light duty milling machine meant for basic operations. Plain Milling Machine Plain milling machine is similar to hand milling machine but feed movement can be powered controlled in addition to manual control.
Mar 14, 2012· Indexing or dividing_head. 2. 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
TYPES OF MILLING MACHINES KNEE-TYPE MILLING MACHINE Knee-type milling machines are characterized by a vertically adjustable worktable resting on a saddle which is supported by a knee. The knee is a massive casting that rides vertically on the milling machine column and can be clamped rigidly to the column in a position where the milling head

May 09, 2009· Index milling machine 745 ??? Today, I looked at an Index model 745 milling machine. It was impressive. The serial number is 14620. Can anyone comment on age and give "pros and cons" of this milling machine? I have two Leblond lathes and was thinking of selling one and getting a milling machine and starting the research.
Indexing (motion) When indexing a machine part, its new location is known to within a few hundredths of a millimeter (thousandths of an inch), or often even to within a few thousandths of a millimeter (ten-thousandths of an inch), despite the fact that no elaborate measuring or
A simple or plain type diesinker is similar in its general arrangement to a vertical-milling machine. The cutters used are such which will assist as far as possible obtaining whatever shape required for die cavity.
