OPTIMUM TU 5620 V MANUAL LATHE

Technical Description

The OPTIMUM TU 5620 V manual lathe is a heavy-duty, precision-engineered machine designed for versatile metalworking applications. It features a robust swing capacity of 22.05 inches (560 mm) and a generous center distance of 78.74 inches (2000 mm), allowing machining of large components. The lathe’s spindle offers a 4.13-inch (105 mm) bore for accommodating sizable workpieces and operates at speeds up to 1600 RPM, powered by a 10.06 HP (7.5 kW) motor controlled via an electronic Siemens frequency inverter for infinitely variable speed adjustment, ensuring consistent power delivery and flexibility. The machine boasts a swing over the cross slide of 13.98 inches (355 mm), facilitating precise cross-sectional machining. It incorporates a hardened and ground Z-axis guideway and a finely ribbed, induction-hardened cast iron bed for enhanced rigidity and durability. The spindle is mounted on adjustable precision tapered roller bearings with guaranteed concentricity of the spindle nose better than 0.015 mm, ensuring high accuracy and smooth operation. Additional features include handwheels with adjustable fine scales (0.04/0.02 mm), adjustable tailstock capable of taper turning ±10 mm, quick tool-free adjustments, a coolant system with separate tank and level indicator, and safety features such as an emergency stop and lockable main switch. The lathe also supports multiple feed rates, with feed ranges on the X and Y axes spanning 0.059 to 1.646 mm/rev and 0.020 to 0.573 mm/rev respectively, suitable for a variety of cutting and threading tasks. It is equipped with tooling such as 3- and 4-jaw chucks, fixed and following steadies, and tool cutter holders, enabling comprehensive manual machining operations. The OPTIMUM TU 5620 V is a German-made machine balancing power, precision, and operational safety for demanding workshop environments.
