2008 BRIDGEPORT XR760 VERTICAL MACHINING CENTER

Technical Description

The 2008 Bridgeport XR760 is a 3-axis vertical machining center produced by Hardinge Inc. under the Bridgeport brand, sharing specifications with the 2007 production year. The machine features a 35.4-inch by 23.6-inch worktable with a 30-station side-mount automatic tool changer and a CT 40 or BT 40 Big-Plus spindle taper. The spindle motor delivers 25 HP (18.5 kW) at a maximum speed of 12,000 RPM. X-axis travel is 30 inches (760mm), Y-axis travel is 24 inches (610mm), and Z-axis travel is 24 inches (610mm). The machine is equipped with a Fanuc 18i-MB CNC control providing high-speed contouring, rigid tapping, and Look Ahead processing. Rapid traverse rates reach 1,692 IPM on X/Y and 1,417 IPM on Z. The XR760 is built on a grey cast-iron base with 45mm linear roller guideways. Standard equipment includes flood coolant, through-spindle coolant, automatic lubrication, and chip conveyor. Overall machine dimensions are approximately 155 inches long by 92 inches wide by 92 inches tall, with a machine weight of approximately 16,000 lbs. The 2008 XR760 benefits from one additional year of production refinement and represents a mature, stable configuration of this model. The Fanuc 18i-MB control is globally supported with readily available service technicians, parts, and documentation. The XR760 is well suited for production of precision components where a 30-inch X travel is sufficient and the full 24-inch Y and Z envelope is required.
