Indexing Heads for 8 inches to 12 inches Phase II Horizontal Rotary Tables. Phase II Indexing heads or Dividing Plates (241-101) allow you to precisely divide a circle into a number of divisions or degrees. The indexing feature helps prevent errors during the repetitive adjustments required in indexing work. The dividing plate set is used to divide one 360° table rotation into divisions of 30". The gear ratio of the compatible horizontal rotary table is 1:90. This means that 90 rotations of the handwheel rotate table one full rotation. This model of dividing plate accessories is compatible with Phase II horizontal rotary tables of size 8 inches, 10 inches and 12 inches. Therefore for one full rotation of the table, the number of handwheel rotations per division "N" times the number of divisions "T" is equal to 90 rotations of the handwheel. So N x T= 90 or N = 90 ÷ T. Say for example, if 17 divisions are required for indexing on a workpiece, then T=21, so N= 90/17 =55/17 = 5 10/34. With 5 full handwheel rotations, 17 divisions are covered and the rest 10/34 by one handwheel rotation. The 10/34 of a handwheel rotation is obtained by using the dividing plates. The annular holes as provided in the dividing plates permit the required number of divisions of one handwheel rotation. The weight of the dividing plate is about 5 lbs.

The reverse rotary table is perfect for using on the tilting angle table. The reverse mount allows access to the handwheel from the front of the machine (see photo below). If you used a standard rotary table in the previously described set-up, the handwheel would be mounted facing the backside of the X-axis.

NOTE: When the worm housing is reversed to the opposite side, a clockwise rotation of the handwheel or stepper motor will result in a counter-clockwise rotation of the rotary table.

The rotary tables can hold more weight when they are not under a continual load. Click on the Video tab above to see examples of different weights and uses for our rotary tables.

This accessory offers a great variety of setup options. With the base mounted square to the mill table, parts mounted to the tilted table can be machined or drilled at precise angles. It can be set at any angle from 0° to 90°. The hole pattern in the table accepts Sherline’s mill vise and rotary table. A threaded chuck mount is also included, which means parts from the lathe can have machining operations done on them without removing them from the chuck. They can then be put back on the lathe for further operations without re-centering.

With the rotary table mounted to the table and tilted, many additional machining possibilities are opened up. The pre-drilled and tapped hole pattern is laid out so that when the rotary table is rotated to the 90° position, its center is the same height as the right angle adjustable tailstock P/N 3702. This eliminates the need for the P/N 3701 right-angle attachment.

Like the 90° Angle Plate P/N 3559 and the Rotary Table P/N 3700, this accessory can also be useful for setups on other machines besides your Sherline machines.

A rotary table is a precision work positioning device used in metalworking. It enables the operator to drill or cut work at exact intervals around a fixed (usually horizontal or vertical) axis. Some rotary tables allow the use of index plates for indexing operations, and some can also be fitted with dividing plates that enable regular work positioning at divisions for which indexing plates are not available. A rotary fixture used in this fashion is more appropriately called a dividing head (indexing head).

The table shown is a manually operated type. Powered tables under the control of CNC machines are now available, and provide a fourth axis to CNC milling machines. Rotary tables are made with a solid base, which has provision for clamping onto another table or fixture. The actual table is a precision-machined disc to which the work piece is clamped (T slots are generally provided for this purpose). This disc can rotate freely, for indexing, or under the control of a worm (handwheel), with the worm wheel portion being made part of the actual table. High precision tables are driven by backlash compensating duplex worms.

The ratio between worm and table is generally 40:1, 72:1 or 90:1 but may be any ratio that can be easily divided exactly into 360°. This is for ease of use when indexing plates are available. A graduated dial and, often, a vernier scale enable the operator to position the table, and thus the work affixed to it with great accuracy.

Rotary tables are most commonly mounted "flat", with the table rotating around a vertical axis, in the same plane as the cutter of a vertical milling machine. An alternate setup is to mount the rotary table on its end (or mount it "flat" on a 90° angle plate), so that it rotates about a horizontal axis. In this configuration a tailstock can also be used, thus holding the workpiece "between centers."

With the table mounted on a secondary table, the workpiece is accurately centered on the rotary table"s axis, which in turn is centered on the cutting tool"s axis. All three axes are thus coaxial. From this point, the secondary table can be offset in either the X or Y direction to set the cutter the desired distance from the workpiece"s center. This allows concentric machining operations on the workpiece. Placing the workpiece eccentrically a set distance from the center permits more complex curves to be cut. As with other setups on a vertical mill, the milling operation can be either drilling a series of concentric, and possibly equidistant holes, or face or end milling either circular or semicircular shapes and contours.

with the addition of a compound table on top of the rotary table, the user can move the center of rotation to anywhere on the part being cut. This enables an arc to be cut at any place on the part.

Additionally, if converted to stepper motor operation, with a CNC milling machine and a tailstock, a rotary table allows many parts to be made on a mill that otherwise would require a lathe.

Rotary tables have many applications, including being used in the manufacture and inspection process of important elements in aerospace, automation and scientific industries. The use of rotary tables stretches as far as the film and animation industry, being used to obtain accuracy and precision in filming and photography.
