SUMMIT BIG SWING 42X160 MANUAL LATHES

Technical Description

The SUMMIT BIG SWING 42X160 Manual Lathe is a heavy-duty precision machine designed for large and demanding machining tasks. It features a robust 42-inch swing over the bed and a long center distance of 160 inches, allowing for machining of unusually large workpieces. The lathe is equipped with a 6.09-inch spindle bore, accommodating substantial bar stock and enabling through-spindle work. Constructed from high-grade cast iron with heavily ribbed castings for enhanced rigidity and vibration damping, the lathe ensures long-term stability and precision. Its bedways are induction hardened and precision ground, with extra-wide surfaces for superior accuracy and wear resistance. The headstock includes a forged chrome alloy spindle mounted on precision taper roller bearings for durable, smooth operation under heavy axial and radial loads. The machine provides a quick-change gearbox suitable for cutting American (inch), metric, and module threads, enhancing versatility. Rapid traverse capabilities are controlled via a 4-way joystick for efficient carriage movement. Additional standard features include a clutched headstock, two-speed tailstock, thread dial, steady rest, follow rest, coolant system, taper attachment, work light, full-length splash guard, and multiple jaw chucks. This lathe balances rugged oil country durability with precision machining capabilities, making it suitable for heavy industrial applications requiring large-scale turning with high reliability and accuracy. Power and tooling support enable efficient and precise metalworking for large-diameter and long-length components.
