The Tongtai iTD-2000YBC CNC turning center, available from Absolute, features a rigid, ergonomic 75-degree bed cast from Meehanite and designed for chip flow and operator accessibility. The bed is said to simplify the programming of the optional Y axis, as the axis runs perpendicular to the X axis, similar to a vertical machining center. The machine’s X-axis cross travel measures 9.05", Z-axis longitudinal travel is 23.6", B-axis subspindle travel is 24.8", and optional Y-axis travel is ±2" from the center line. The true linear Y axis is said to provide turret movement perpendicular to the X axis for complex off-center milling functions.

The main spindle is driven by a 20-hp, high-torque motor designed to provide power and fast acceleration ranging to 4,500 rpm. In addition, the 5,000-rpm subspindle is driven by a 10-hp, high-torque integral motor spindle. According to Absolute, the spindles are synchronized on the fly for part transfer to the subspindle. Rapid traverse rates are 1,181 ipm for the X, Z, and B axes and 590 ipm for the Y axis. The company says the high rapid-traverse rates achieved with 45-mm roller-type linear ways reduce non-cutting time.

The turning center includes a 12-station bidirectional servo BMT-65 turret (16-station BMT-55 optional) that enables 0.3-sec. indexing and coolant through the toolholders. A full C axis with live tools is standard for milling operations on both the main subspindles. The FANUC OiT-F CNC control is equipped with operator-friendly features including Manual Guide i Conversational. Standard equipment also includes a tool setter and chip conveyor.
