The SOUND SJL 50 is a precision engine lathe designed for general-purpose turning and shaft work operations. Featuring a 47.24-inch swing, this machine accommodates workpieces up to approximately 23.62 inches in diameter, making it suitable for mid-sized components in automotive, manufacturing, and job shop applications. The impressive 196.85-inch center distance provides substantial working length, enabling the machining of extended shafts and cylindrical parts with minimal setup adjustments. The spindle bore of 4.13 inches allows for the passage of bar stock and supports various spindle-mounted accessories, collets, and chuck configurations. As a manual lathe, the SJL 50 relies on operator skill and control for feed rates, depth of cut, and spindle speed adjustments, offering flexibility for complex operations and custom work that may require judgment-based decision-making during the cutting process. This class of engine lathe typically incorporates a robust cast-iron bed construction for stability and vibration damping, essential for achieving tight tolerances and quality surface finishes. The machine's specifications position it within the mid-range industrial lathe category, suitable for small to medium production runs, prototype development, and repair work where versatility and operator control are prioritized over fully automated production. The SJL 50 represents a dependable platform for manual machining operations, combining adequate capacity with the mechanical simplicity and ease of maintenance characteristic of conventional lathes, making it a practical choice for experienced machinists and tool rooms requiring reliable, versatile turning capabilities.
