A turbo among rotary tables – the new FIBRODYN DA direct driven rotary tables with torque motor are optimally suited for all handling and assembly applications that require the shortest indexing times and flexible positioning. Thanks to its measuring system directly in the rotary table axis, any position can be moved to with the highest precision. The slim design with its very space-saving, compact construction and its fitted boreholes makes it very easy to integrate the rotary tale into your system. FIBRODYN DA is also available as decentralized stand-alone solution with integrated control. In this version, it offers the ideal opportunity to save a separate external NC control to minimize the implementation and start-up costs and to realize small machines without complex peripherals. The rotary tables are lifetime lubricated and maintenance free.

Sherline has taken their accurate and reliable 4″ rotary table into the 21st century with the addition of Computer Numeric Control. Clock-makers or anyone with a need to cut gears or other complicated radially symmetrical patterns will find this accessory takes all the headaches out of repetitive indexing operations.

The rotary table comes with clamps and T-nuts for attaching it to the T-slots of a Sherline mill table. In addition, there are two options available for mounting the table in the vertical position or at other angles:

Right-Angle Attachment—This plate holds the table in the vertical position with a center height of 2.7″. A right-angle tailstock is also available to support long stock held on center in the rotary table.

Tilting-Angle Table—This table holds the rotary table and can be fixed at any angle from 0° to 90°. In the 90° position, the rotary table center is also at the 2.7″ height, which allows the right-angle tailstock to be used with it.

After entering the number of steps per revolution (or the number of degrees per step) on a simple numeric keypad, the table advances quickly and precisely to the next position at the touch of a single advance key. If an error is made, previous positions can be accurately recalled by hitting another button. Basic resolution is 28,800 steps per revolution, ±0.006° per step. This allows the accurate machining of items like gears with odd numbers of teeth. Computations are made internally to a high degree of accuracy to avoid cumulative errors.

Sherline has taken its P/N 3700 manual 4″ rotary table and applied a stepper motor mount with dampened coupling in place of the handwheel. The mount accepts a NEMA #23 frame-size stepper motor for CNC control. This allows the table to be used as a 4th axis with CNC systems that have the capability to drive a rotary axis.

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.

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 product range includes single and multiple axes, tilt/rotating tables, and indexing and high-speed spindles. Additionally, we offer customized solution tables for customer requests or OEM projects.

Even for EDM machines that have been in use for decades, we will work with you to determine the ideal rotary indexing table and/or rotating/indexing spindle solution.

Our state-of-the-art rotary indexing tables and customizable reference and clamping systems provide endless application possibilities and highly efficient solutions.

The robust geared rotary tables of the 500 series are extremely flexible to use and, thanks to the combiFLEX® modular system, can be converted or extended at any time to meet new machining tasks. The rotary tables are not only suitable for positioning operation, but can also be used for short simultaneous machining operations. The preloaded gear and the powerful bearings allow high long-term accuracies as well as large spindle loads. The maximum clamping force of up to 7,000 Nm leaves hardly anything to be desired.
