The TB series is Tongtai's 60-degree slant-bed CNC lathe, built with a symmetric saddle for even airflow and less heat distortion. A 12-station VDI 40 turret and preloaded ball screws hold precision across long runs, with a Y-axis and sub-spindle available.

Why does saddle design matter on a slant-bed lathe?

Heat distorts the saddle, and a distorted saddle moves the tool off the part as the shift wears on. The TB series' symmetric saddle circulates air evenly and the preloaded ball screw resists thermal growth, so the 620 mm swing holds its accuracy from the first part of the day to the last.

• 620 mm swing, 330 mm turning diameter
• A2-6 spindle, 4,500 rpm, 51 mm bar
• 12-station VDI 40 turret
• Optional Y-axis and sub-spindle

Against a flat-bed machine, the TB series sheds chips and heat together — the stability a high-volume run needs to stay in tolerance.
