Technical Description
This multi-spindle CNC lathe is powered by a robust 35 hp main motor and controlled by a FANUC 31i-B system, delivering sophisticated multi-axis machining capabilities. The machine features dual spindles: a primary spindle rated at 4,000 RPM with a 6-inch nose and 3.15-inch bore, paired with a sub-spindle operating at 5,000 RPM with a 5-inch nose and 2.17-inch bore, each independently powered. The bar capacity accommodates 2.56-inch diameter stock, while the 8-inch main chuck and 6/8-inch sub-chuck enable secure workholding across diverse applications. With a 20-inch swing-over diameter and 37.5-inch distance between centers, this machine handles mid-range component production efficiently. The three turrets with 12 stations provide 192 available tools, while the 36 live tool stations offer 72 live tools operating at 4,000 RPM, enabling simultaneous turning and milling operations. Rapid traverse rates reach 1,181 IPM on the Z-axis and 708 IPM on X/Y axes, with B-axis positioning up to 1,181 IPM, ensuring minimal non-cutting time. Turret indexing completes in 15 seconds, and the 4.72-inch offset stroke facilitates complex part profiles. This machine exhibits moderate service history with 10,352 power-on hours, 5,719 run hours, and 1,069 cutting hours. The precision FANUC 31i-B control system provides nanometer-resolution interpolation and advanced tool path optimization, ideal for high-speed, high-accuracy production of complex geometries in automotive, medical, and aerospace sectors.
