The RB212 is a reliable and powerful Double Column Bridge Machining Center from the RB Series, built for power and endurance in heavy jobs that require both high accuracy and productivity. Its heavy-duty, fixed rail bridge design provides exceptional stability and rigidity, essential for precision machining of large components.

The work surface is an ample 78-7 inch x 43-3 inch table with a substantial maximum table load of 7,700 lbs (3,500 kg). The machining envelope is defined by generous travels: 83-5 inches of X-axis travel (2,120 mm), 47-2 inches of Y-axis travel (1,200 mm), and 31-5 inches of Z-axis travel (800 mm).

This bridge machine features high-quality construction elements to ensure smooth and accurate operation, including roller guides on its axes and a Nitrogen counter balancer on the headstock. Machining power is provided by a two-speed, geared #50 spindle which achieves speeds up to 6,000 RPM and produces 388 ft-lb of torque (526 Nm), making it suitable for tough materials like high-temperature alloys, ferrous metals, and non-ferrous metals. High efficiency is maintained with a rapid feed rate of 945 inches per minute (24 m-min) across all axes. The machine guarantees precision with a linear position accuracy of plus-minus 0-0006 inches (0-015 mm) full travel and a linear repeatability of plus-minus 0-0001 inches (0-003 mm). Tool management is flexible with a Tool Storage Capacity of 32 standard or optional 40 or 60 tools.
