Product Description

This series NC large-through-hole horizontal / vertical rotary table is the important accessory for various NC borers, NC millers and CNC machining centers. It can be mounted on the working-table of the main machine with its spindle either parallel or perpendicular to the working-table of the main machine and used as the fourth spindle of the main machine. Controlled by the main machines controlling system or the rotary tables independent controlling system, this NC rotary table works with the main machine and performs all necessary indexing rotations.
The workpieces in shapes of plate, disk and other complex shapes can be fixed to this series of rotary table and machined. Utilizing the large through hole in the spindle of the rotary table, hydraulic (or pneumatic) actuating collets or chucks can be attached to the rotary table so that workpieces in long-shaft types can be also fixed between the rotary table and the tailstock and machined. This series rotary table helps the main machine to achieve high-precision machining process.
