HARDINGE-BRIDGEPORT XR-760 VERTICAL MACHINING CENTER

Technical Description

The Hardinge-Bridgeport XR-760 is a high-performance 5-axis vertical machining center engineered for precision manufacturing of complex geometries. Featuring a vertically oriented spindle with a 25-horsepower motor operating at 12,000 RPM, the machine delivers rapid traverse rates of 1,692 IPM on X/Y axes and 1,417 IPM on the Z-axis, enabling efficient material removal and reduced cycle times. The machine accommodates workpieces on a 35" x 23.6" worktable with a maximum load capacity of 2,000 pounds, supported by rigid 45mm linear guideways and double-nut ballscrews that ensure superior positioning accuracy and repeatability. With 30 inches of X-axis travel, 24 inches of Y-axis travel, and 24 inches of Z-axis travel, the XR-760 provides substantial working envelope for diverse part geometries. The spindle-to-table surface clearance ranges from 3.94" to 27.9", accommodating various workpiece heights. Equipped with a 30-station automatic tool changer (ATC) and CAT-40 spindle taper, the machine minimizes tool-change downtime while maintaining high positioning precision. The robust cast iron construction, weighing 16,000 pounds with overall dimensions of 155" x 92" x 92", provides excellent rigidity for consistent machining quality and reduced vibration. Control options include Fanuc 18i-MB or Heidenhain iTNC 530 systems, offering advanced CNC capabilities for complex part programming and execution.
