Technical Description
The SUMMIT 24-4 x 120B Manual Lathe is a heavy-duty, precision-engineered machine designed for demanding turning applications. Constructed entirely from cast iron, it delivers exceptional rigidity and vibration absorption for consistent accuracy and durability. The lathe features a 25-inch swing over the bed, 17-inch swing over the cross slide, and a 120-inch distance between centers, making it suitable for large and complex workpieces. The spindle boasts a generous 4.13-inch through-hole and a D1-8 camlock nose, supporting a wide range of chucking and workholding options. With a 15 horsepower main drive motor, the lathe achieves spindle speeds from 20 to 1,250 RPM across 21 steps, providing flexibility for various materials and cutting conditions. The quick-change gearbox enables efficient cutting of American (inch), metric, module, and diametrical pitch threads, while the 4-way rapid traverse joystick enhances operator productivity. Standard features include a cross-ribbed headstock, hardened and ground alloy steel gears, precision chrome alloy spindle, clutched headstock for improved control, and hardened, ground bedways for long-lasting accuracy. The lathe also includes a two-speed tailstock, thread dial, steady rests, follow rest, taper attachment, coolant system, carriage stop, work light, full-length splash guard, and a 3-jaw chuck. Measuring 48 inches wide, 60 inches high, and 194 inches long, and weighing approximately 9,000 pounds, this lathe is built for stability and heavy-duty industrial use.
