MIGHTY VIPER B-4000GTDW VERTICAL MACHINING CENTER

Technical Description

The Mighty Viper B-4000GTDW is a twin-spindle, bridge-type CNC vertical machining center featuring dual 35 HP spindle motors capable of 6,000 RPM geared operation. The machine boasts a substantial work envelope with 160 inches of X-axis travel, 80 inches of Y-axis spindle head travel, and 32 inches of Z-axis vertical travel. The expansive 165" x 100" working table accommodates workpieces up to 45,000 pounds, while the 108.3-inch width between columns and 40-inch distance between twin spindles enables simultaneous or sequential machining operations. Spindle nose positioning ranges from 5.3 to 37.6 inches above the table surface, providing flexible setup configurations. The machine delivers rapid traverse rates of 393 IPM across all three axes with cutting feedrates reaching 276 IPM. Each spindle is equipped with dual 20-station automatic tool changers (40 total tool capacity per spindle), capable of handling tools weighing up to 33 pounds with maximum dimensions of 7.8" x 14". The system utilizes CAT50 tool shanks with P50T-1 pull studs and features a drum-type tool changer with random tool selection capability. Control is managed by a Mitsubishi M530 CNC system, with the machine incorporating standard accessories including automatic lubrication, coolant systems, spindle oil coolers, chip conveyors, and thermal management systems. At 15,900 hours of operation, this 2006-vintage machine represents a capable platform for high-volume production and complex multi-spindle machining applications requiring precision and throughput.
