TRAUB TNK 28/36 CNC LATHE

The Traub TNK 28/36 is a fixed headstock, single spindle CNC automatic lathe engineered for producing standard screw machine parts in higher lot sizes from bar stock. This German-manufactured machine features a maximum turning diameter of 36 mm (approximately 1.42 inches) with a bar capacity of 3 inches and a turning length of 8.3 inches, making it well-suited for precision component production. The machine is equipped with a main motor rated at 9 HP, delivering robust cutting power at maximum spindle speeds of 6,300 RPM. With a tool capacity of 22 positions across dual turrets—12 stations on the front attachment and additional positions on the backworking attachment—the TNK 28/36 provides exceptional machining versatility. The CNC control system utilizes the Traub TX8i controller, enabling precise, repeatable machining operations. The machine measures 3.4 × 1.3 × 1.7 meters and weighs 4,000 kg, featuring a bar feeder compatible with material diameters ranging from 5-42 mm and maximum bar length of 3,200 mm. Advanced features include integrated motorspindle synchronous drive technology for compact, high-power design and active temperature control for optimal thermal stability. The machine includes a chip conveyor for efficient material handling. Designed for high-volume production of complex screw machine components, the TNK 28/36 combines Swiss-precision engineering with modern CNC automation, making it ideal for manufacturers requiring reliable, multi-axis capability in a compact footprint.
