I"d also suggest that you allow the work you do to help make the decision on rotab size. If you do nothing but small work a 6" table may be fine, but if you intend to pursue a wide variety of work, you"ll come to cuss that small table. They"re geared faster, so using them for large work isn"t very convenient, even if you can mount the work. No problem if you"re just drilling, but if you have to do any milling, it"s harder with a fast table.

The real issue is that a small table can be far more difficult to use for larger work, often eliminating the chance to make the required setup because there"s no surface left after placing the work piece on the table.

Just my 2 cents. Buy a larger rotary table, you"ll appreciate the extra real estate for clamping. If you can, steer clear of the combo horizontal/vertical ones, it"s just extra weight. When you finally have the need, buy a dividing head and foot-stock for horizontal work on the mill.

The Benchmaster Mill table measures 6 by 18 inches. The mill has limited space of about 8 inches from table top to bit bottom. I"ll keep looking for a 6 inch that has more than 3 slots and a low price. At this time i am not interested in the tailstock.

You can put a vise on a rotary table but consider the vise is a chuck. Consider the ability to turn a piece and remove it from the lathe and sit it upon that table and it perfectly centered. That is because you"ve made a center plug to fit the center of your table. The center can end to a thread matching the chuck, threaded or taper. Then again many Many chucks use 3 bolts to attach to the backplate anyway, so there could with centering plug, a chuck affixt quickly which when tightened aligns to center. Then only snug up the pass-thru studs to T nuts.

I have a small aluminum cylinder, 1.00" dia. and 1.00" height. I"d like to drill three holes in the base, equally spaced from the center and from each other (a minimalist bolt hole pattern), and so I believe that a rotary table might simplify the job.

My question is, what is the best or easiest way to hold the workpiece on the table? I"d like to be able to drill a bunch of these, so I need something that is easily repeatable. Is there some way to hold a collet in place in the center of the table, so that the collet can hold the workpiece? Or perhaps a 3-jaw chuck from a mini-lathe centered on the rotary table would do the trick? Or maybe I just need to clamp a vee block to the table?

Sounds like you have only one part. Mounting a rotary table for a one off is a lot of work, and dialing in a 1" diam part on the table, and holding it there is a PITA for one item.

The South Bend rotary table, in addition to being a worthy machine accessory, commands a fairly high collector premium. South Bend stuff is hot these days, and the rotary table is one of several that head the list of most desirable accessories.

As you can see, quite a range! One little exercise that might help is to convert the original selling price for the turntable to current dollars. For example, the RTB101 sold new in 1963 for $61.75. Converting this price to 2009 dollars gives you $453.82(!) This is what the same item might sell for today, if it was still being sold. From this point, one needs to factor in all manner of subjective criteria, such as collector premium (how many people want one?), condition, how badly you want it, how badly the seller wants to sell it, your relationship with the seller, etc.

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.

Our direct drive rotary tables provide high torque and are easy to integrate. They contain high-energy magnets in a simplified mechanical design and drive loads directly without the need for a transmission mechanism or gearbox. It allows customers to build them right into a drive system for flexible placement and integration with cooling pipes and cables, for example.

We supply a wide range of frameless motors, and our adjustable motors include an optical encoder, scale, bearing and housing. Given our selection, it can be challenging to choose the best direct drive motor for your project. Our engineers prefer to help you find the right rotary table for your requirements.

Our most popular rotary motor, the AXD series is characterized by a slim, compact "pancake" design with high peak and continuous torque despite the motor"s quite small form factor.Direct drive and brushless motor

The ACD series is a set of ironless rotary tables. This motor is cogging-free and features high-resolution optical encoder feedback and low speed variability. This permanent magnet motor is equally suited for either low or high speed applications.Zero cogging coreless motor
