Tongtai TD-2000YBC Sub-Spindle, Multitasking Y-Axis Turning Center


iTD-2000YBC is an advanced, high-precision CNC turning center cast from Meehanite iron.  


The system is loaded with innovative features not found on comparable machines in its class. This machine features a rigid, ergonomic, and super-accurate 75-deg. bed design for excellent chip flow and operator accessibility. The 75-deg. bed also simplifies the programming of the optional Y-axis as the Y-axis is perpendicular to the X-axis like a vertical machining center. High rapid-traverse rates using 45 mm roller-type linear ways are also achieved to reduce non-cutting time.


X-axis cross travel is 9 in., Z-axis longitudinal travel is 24 in., B-axis sub-spindle travel is 25 in., and optional Y-axis travel is +/-2 in. from the center line. The main spindle is driven by a 20 hp, high torque motor which provides power and fast acceleration at 4,500 rpms. The 5,000 rpm sub-spindle is driven by a 10 hp high torque integral motor spindle. The spindles are synchronized on the fly for part transfer to the sub-spindle. Rapid traverse feed rates for X, Z, and B-axes are 1,181 in./min. and 590 in./min. on Y. Standard equipment also includes a tool setter and chip conveyor.


A 12-station bi-directional servo BMT-65 (16-station BMT-55 optional) turret provides 0.3-second indexing and coolant through the tool holders. A full C-axis with live tools is standard for milling operations on both the main sub-spindles. The true linear Y-axis provides turret movement perpendicular to the X-axis for complex off-center milling functions and easy programming. The Fanuc OiT-F CNC control is standard and fully loaded with operator-friendly features including Manual Guide i Conversational
