Since you mention production, I"m assuming the very many small optical stage tables are not suitable because they can"t withstand machining forces. But if the job is inspection, not machining, lots of options open up that you won"t find in the McMaster-Carr or MSC catalogs.

I have questions about what sort of things your students will be doing, and how they intend to fasten/clamp work to the table. I find that a 9" diameter table with T-slots is limited to surprisingly small parts when conventional clamping hardware is used. Plan to use a subplate mounted to the rotary table and used as a glue chuck or as a custom fixture? Milling? Drilling? Grinding?

What sort of angular resolution and repeatability do you need? Would a direct indexer with an angle scale work? Do you need the precision of setting angles with gage block stacks? Do you need to rotate the table while machining?

They aren"t intended as rotary tables, but you could probably adapt a Suburban, Harig or Hermann Schmidt spin and index fixture as the basis of a small rotary table if you don"t need to change angles while actively cutting. These are generally intended for grinding, but will stand up to light milling, and would certainly meet any requirements for quality and service life! Hermann Schmidt makes a small horizontal "flatspin" fixture about the size you want, but it"s a 24-position direct indexer, no angle scale or clamp.

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.

I"ve used my 6" Asian made rotary table probably 6 to 8 times in the 10 or 12 years that I"ve had it. It has worked well for those jobs. No slop, very little backlash or drag of the gears when engaged fairly snugly on the eccentric. I bought the indexing plates and sector arms kit with it but have never used those parts. But then I"ve never tried to make any gears. Most of the uses have been for indexing to degrees of accuracy that only needed using the degree wheel. Two jobs involved actually using it to rotate the part while milling away a circular portion.
