NAGI 550-12 MANUAL LATHE

Technical Description

The NAGI 550-12 is a manual engine lathe designed for precision turning operations on mid-range workpieces. With a swing capacity of 61.0 inches, this machine accommodates workpieces up to approximately 30.5 inches in diameter, making it suitable for general machining applications in automotive, aerospace, and industrial manufacturing environments. The 78.0-inch center distance provides adequate workspace for extended workpiece lengths, enabling efficient production of shafts, bushings, and similar cylindrical components. This lathe features robust construction with precision spindle bearings and hardened, quenched rails that ensure dimensional accuracy and repeatability. The manual operation allows skilled machinists direct control over spindle speed, feed rates, and tool positioning, providing flexibility for custom jobs and prototype work. The machine is equipped with multiple chuck options, including 4-jaw independent chucks in various sizes and 3-jaw scroll chucks, facilitating rapid workholding setup for diverse workpiece geometries. The NAGI 550-12 incorporates a DC motor-driven spindle with variable speed control, typically ranging from 50-2250 RPM depending on specific configuration, enabling optimization for different material types and cutting operations. Standard accessories include live centers, face plates, and taper cutting attachments, supporting turning, boring, threading, and grooving operations. The lathe's rigid construction and proven design make it an economical choice for job shops and production facilities requiring reliable, manual precision turning capability without the complexity and maintenance demands of CNC systems.
