The CNC-TAKANG TK670/4000 manual lathe is a heavy-duty precision machine engineered for large-scale turning applications. It features a maximum swing capacity of 26.3 inches and between-centers length of 157.6 inches, enabling it to handle long workpieces with substantial diameters. The spindle bore measures 4.0 inches, accommodating large tooling and allowing for heavy-duty work. Driven by a robust 15 HP motor, the lathe achieves spindle speeds up to 1,000 RPM to optimize cutting efficiency. The swing over the cross slide is 18.1 inches, providing additional flexibility for machining operations close to the tool post. Constructed with a flat bed design, the TK670/4000 incorporates two extra-wide pitch V-ways and a 45° slant way for the saddle, combined with box ways on the turret, to ensure high rigidity and power transmission during heavy cuts. The headstock includes a multi-speed spindle gearbox designed to deliver broad gear ratios and superior torque, suitable for heavy-duty and precision tasks. A hydraulically controlled tailstock with spindle-grade bearings supports long workpieces to maintain machining accuracy and reduce vibrations. The lathe complies with VDI and ISO precision standards, with all critical components dynamically balanced and multi-axis laser inspected to guarantee stability and precision across operations. This lathe’s design focuses on reliability, precision, and heavy-duty performance, making it suitable for demanding industrial turning tasks requiring both large capacity and fine accuracy. Standard accessories and options include coolant units, auto lubrication systems, and spindle cooling, further enhancing operational efficiency and longevity.
