2011 Mighty Viper VT33-BL CNC Turning Center

The Mighty Viper VT33-BL is a heavy-duty big-bore CNC turning center built for the large-diameter, thick-wall work that defines oil-field, energy, and heavy-component machining. This 2011 example pairs a 5.15" spindle bore and 4.5" bar capacity with a 15" chuck on an A2-11 spindle nose, turning up to 19" in diameter within a 27" swing over the bed. A 35 HP spindle (50 HP optional, 30-minute rating) drives cuts to 2,400 RPM, while a 12-station turret and 9.4" X-axis travel keep heavy roughing and finishing on one rigid slant-bed platform.

Compared with the standard-bore Mighty Viper VT33 and earlier small-bore turning centers in the class, the VT33-BL is the big-bore, high-torque evolution built to pass far larger stock through the spindle. The 5.15" bore and 4.5" bar capacity open up pipe, coupling, and large-shaft work the standard VT33 simply cannot chuck, and the 35/50 HP spindle brings the torque to hog heavy material without stalling. For a shop that keeps turning away oversized jobs, stepping up to this VT33-BL converts those lost quotes into billable spindle time - a meaningful capacity gain, not just a newer machine.
