The Sharp 2660B manual lathe is a heavy-duty precision machine designed for large-scale and high-capacity machining tasks. It features a robust 26-inch swing over the bed and a 60-inch distance between centers, accommodating substantial workpieces. Its spindle bore measures 4.5 inches with a D1-11 camlock spindle nose, enabling versatile tooling setups. Power is delivered by a 15-horsepower motor, driving the spindle through a 12-speed gearbox offering speeds ranging from 10 to 1,000 RPM, ensuring both high torque for heavy cutting and fine control for precision operations. The lathe’s bed is a rigid one-piece Meehanite casting, 16 inches wide, with hardened and ground ways for durability and accuracy. It supports direct selection of both inch and metric threads, enhancing versatility. The machine measures 114 inches in length, 41 inches in width, and 52 inches in height, weighing approximately 5,786 pounds, which contributes to its stability during operation. Additional features include a quick-change gearbox, quill with MT #5 taper, and options for digital readouts and double chucks. The spindle assembly is supported by high precision tapered roller and ball bearings for sustained accuracy. This lathe is suitable for industrial environments requiring robust performance and reliability for machining large and complex components.
