Hardinge and Bridgeport make it easy to select and connect a rotary device to the vertical machining center for precision fourth-axis parts positioning. Hardinge fourth-axis rotary tables will increase the machine capability with rapid positioning speeds and fast job change-over. The rigid design characteristics of the machine and the quick-change spindle nose design of the rotary device offer a rugged and flexible fourth-axis machining option.

The Bridgeport GX 1000 OSP machining center is unique to the Bridgeport family of mills as it incorporates the Okuma OSP P200 CNC control, encoders, motors and drives. The advanced architecture of the OSP-P200 NC control enables access to almost any application and peripheral, including factory management systems and will interface with bar coders, feeders, robots, probes and toolsetters to help streamline production, according to Hardinge.

The stiff and thermally stable spindle, rigid C-frame fixed column design and fixed pre-tensioned double nut ballscrews on all axes of the machining center, provide superior rigidity, accuracy and repeatability. Hardinge provides a smooth integration of their precision rotary tables into the GX 1000 OSP, to operate in a fully interpolated fashion with the other axes of the machine.  

Rotary packages include the Okuma motor and cables to connect via fourth-axis to the pre-wired GX 1000 vertical machining center with an OSP control. The Bridgeport VMC must be prewired to accept the rotary package. Rotary systems can also be operated using just the Hardinge servo control if the true fourth-axis is not required.

Hardinge has a large selection of rotary products that are compatible with the Bridgeport GX 1000 OSP machining center including single and multi-spindle units. Hardinge rotary products incorporate an A2-4, A2-5 or 5C threaded-nose, collet-ready spindle that will accept collets, expanding collets, step chucks and chucks (as well as the traditional faceplate) to expand part gripping capabilities and improve part accuracies. The 44.09” × 21.25" Bridgeport machine table provides plenty of room for a rotary table and a vise to allow maximum job flexibility.
