Product Description

This series NC horizontal rotary table is a critical accessory for various NC milling machines, NC machining centers. It can be mounted on the working-table of the main machine with its spindle parallel to the working-table and used as the fourth rotary spindle or the working-table of the main machine. Controled by the controlling system of the main machine, this series NC rotary tables can carry out high-precision machining of equally or unequally spaced holes, slots or continuous special curved surfaces.
Rectangular and circular rotary tables are available as per request of buyers. (NCRT1600, NCRT2000, NCRT2500A models of rotary tables can achieve a ± 2 seconds indexing precision when fit with the angular encoders. )
