1990 BRIDGEPORT INTERACT412 VERTICAL MACHINING CENTERS

Technical Description

The 1990 Bridgeport Interact 412 is a 3-axis vertical machining center produced by Bridgeport Machines, Inc. at its Connecticut facility, representing the compact end of the Interact series VMC lineup. The machine features a 32.8-inch by 12.5-inch worktable and a 12-tool automatic tool changer with a BT 40 spindle taper and power drawbar. The spindle motor delivers 10 HP with a speed range of 540 to 4,000 RPM, suitable for milling, drilling, boring, and tapping operations in steel, cast iron, and non-ferrous materials. X-axis travel is 18 inches, Y-axis travel is 12 inches, and Z-axis travel is 12 inches. The machine is equipped with a Heidenhain TNC 2500 CNC control, providing conversational Klartext and ISO G-code programming with high-accuracy contouring capability. The Interact 412 was built with a rigid cast-iron base and column with precision-ground ballscrews and recirculating-ball guideways on all axes. Standard equipment includes flood coolant, automatic lubrication, and a tool magazine with random access. Shipping dimensions are approximately 84 inches long by 80 inches wide by 91 inches tall, with a machine weight of approximately 5,000 lbs. Power requirements are 230V 3-phase. The 1990 Bridgeport Interact 412 was designed to bring full VMC capability to shops requiring a compact footprint machine, and was well regarded for its build quality and the reliability of the Heidenhain TNC 2500 control. It was popular in toolroom and small-batch production environments throughout the early 1990s.
