SOUND SLL 30 MANUAL LATHE

Technical Description

The SOUND SLL 30 Manual Lathe is a heavy-duty precision machine tool engineered for professional metalworking operations. This industrial-grade engine lathe features an impressive 47.24-inch swing over the bed, enabling operators to work with large-diameter workpieces. The exceptional 118.11-inch distance between centers accommodates extended workpieces for longitudinal turning operations, making it suitable for manufacturing extended shafts, spindles, and similar components. The 4.13-inch spindle bore provides substantial capacity for chuck mounting and tooling versatility, supporting various chuck sizes and work-holding configurations. The machine utilizes precision-ground hardened guideways constructed from high-quality cast iron, annealed to relieve internal residual stress and ensure dimensional stability during extended operation. The bed structure is reinforced with an internal framework to minimize vibration and deflection under heavy cutting loads, essential for maintaining tolerances during precision work. Standard equipment typically includes rapid traverse capabilities for efficient carriage movement, adjustable feed rates for various cutting applications, and a universal gearbox for cutting metric and inch threads. The lathe incorporates manual operation with mechanical control systems, including spindle speed selection via a multi-step pulley system or gearbox arrangement, and hand wheels for precise longitudinal and cross-slide positioning. Additional features commonly found on this class machine include a tailstock with adjustable quill, foot brake pedal for safety, and a coolant system for extended tool life. The robust construction and versatile capacity make the SOUND SLL 30 suitable for job shop environments, tool and die work, and prototype manufacturing applications requiring precision and reliability.
