FUKUNO SEIKI FL-2140 CNC LATHE

Technical Description

This CNC lathe features a swing capacity of 20.87 inches, enabling machining of cylindrical workpieces with diameters up to this specification. The machining length of 39.37 inches provides substantial axial capacity for extended components, making it suitable for producing shafts, bushings, and similar cylindrical parts with extended profiles. The computer numerical control (CNC) system enables precise automated operation through pre-programmed instructions, eliminating manual intervention and ensuring consistent part quality across production runs. The machine's control system automatically manages critical cutting parameters including spindle speed, feed rate, and depth of cut to optimize tool life and surface finish. With CNC operation, typical spindle speeds range from 1500-12,000 RPM depending on material properties, while feed rates are precisely controlled from 0.001-0.005 inches per tooth to achieve desired dimensional accuracy. The machine delivers standard tolerances of ±0.125 mm on critical features, with feasible tolerances reaching ±0.025 mm for high-precision applications. The combination of swing and length specifications positions this lathe for versatile production capabilities, accommodating various material types including steels, aluminum alloys, and composites. CNC automation significantly reduces setup time between operations and minimizes human error, resulting in higher productivity and repeatability. The machine's rigid structure and advanced spindle system maintain exceptional accuracy during high-force cutting operations. This configuration makes the lathe ideal for small to medium production runs requiring tight dimensional tolerances and consistent surface finishes across batch quantities.
