STAMAC ST250K MANUAL LATHE

Technical Description

The STAMAC ST250K is a precision engine lathe engineered for general-purpose turning operations in manufacturing and job shop environments. This manually operated machine features a robust swing capacity of 19.63 inches, enabling the machining of workpieces up to this diameter across its full length. The extended center distance of 118.98 inches provides substantial longitudinal workpiece capacity, making it suitable for medium to long-form components including shafts, cylinders, and tapered parts. Operating at a maximum spindle speed of 1,600 RPM, the ST250K delivers controlled cutting action across diverse material types and finish requirements. The manual operation configuration allows skilled machinists direct control over feed rates, threading operations, and cutting parameters, providing flexibility for both production runs and specialized job work. This design philosophy emphasizes operator control and mechanical reliability over automated functions. The lathe's construction incorporates a substantial bed structure designed to dampen vibration and maintain dimensional accuracy during extended machining operations. The headstock assembly houses the spindle mechanism with integrated gearing for speed selection, while the tailstock provides support for long workpieces and accommodates various tooling attachments. The carriage system enables precise longitudinal and cross-feed movements for finishing operations and complex geometries. The ST250K is particularly effective for operations including cylindrical grinding, taper turning, threading, boring, and facing. Its specifications make it ideal for small to mid-sized manufacturing operations, tool and die shops, and educational institutions requiring reliable manual lathe capability. The combination of adequate swing, substantial center distance, and controlled spindle speed establishes this model as a versatile workhorse for conventional turning applications demanding precision and durability.
