A tool mounted on a milling machine, offering exact rotational management of a workpiece. This permits for operations akin to reducing gears, splines, and slots at particular angles or intervals. For instance, creating equally spaced holes round a round element requires this managed rotation.
This rotational precision enhances the milling machine’s versatility, enabling advanced machining operations that might be troublesome or unimaginable in any other case. It contributes to elevated accuracy and repeatability, lowering errors and enhancing the general high quality of manufactured elements. Traditionally, such exact divisions relied on guide strategies, making this system a major development in machining expertise.
