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.
The CNC rotary indexer is a stand-alone unit. You get everything you need to make complex indexing
jobs easy. In addition, the unit can be connected to an existing CNC control to act in conjunction with
that system. An input signal triggers the programmed function. When it is complete, it signals back to
continue the program. The unit can also be "daisy chained" with other units to trigger sequential
actions. As with all Sherline accessories, complete instructions are included.
The rotary table can also be "daisy chained" with Sherline's linear controller (P/N 8800) to achieve
combinations of rotary and linear movement in sequence. This makes it easy to set up for relatively
sophisticated operations like cutting gears without having to know anything about CNC programming
beyond what is entered from these simple keypads.

Vertical Mounting Options
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:
3701 Right Angle Plate--This plate holds the table in the vertical position with a center height of 2.7".
A right angle tailstock P/N 3702 is also available to support long stock held on center in the rotary
table.
3750 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 that allows the 3702 tailstock to
be used with it.
