SUMMIT BIG SWING 52X240 MANUAL LATHE

Technical Description

The SUMMIT BIG SWING 52X240 Manual Lathe is a heavy-duty, precision-engineered machine designed for demanding turning applications. With a maximum swing over the bed of 52 inches (1,320.8 mm) and a center distance of 240 inches (6,096 mm), this lathe accommodates large and heavy workpieces with ease. The spindle features a generous 6.09-inch (154.9 mm) through-hole, enabling the machining of long bar stock and oversized components. Constructed with a fully ribbed, closed-grain cast iron bed that is induction hardened and precision ground, the lathe ensures exceptional rigidity, vibration damping, and long-term accuracy. The clutched headstock houses a dynamically balanced, anti-friction mounted shaft and a forged chrome alloy spindle for reliable performance under heavy loads. The machine is equipped with a quick-change gearbox capable of cutting American (inch), metric, and module threads, as well as a rapid traverse carriage controlled by a 4-way joystick for efficient tool positioning. Standard features include a two-speed tailstock, thread dial, steady rest, follow rest, coolant system, taper attachment, work light, full-length splash guard, and both 3- and 4-jaw chucks. The 27.5-inch (700 mm) wide bed provides ample support for large workpieces, while the induction-hardened bedways ensure smooth, precise movement. This lathe is ideal for shops requiring high-capacity, versatile turning capabilities with the durability and precision expected from Summit Machine Tool.
