This indexer is specific to the rotary table, and should not be confused with the linear controller.
Operation is very simple
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.
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 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.
Always wear safety glasses when operating machine tools.
