OKUMA MULTUS B250II-1SW/750 CNC LATHE

This advanced multi-axis turning center features an 8-inch main chuck with 2-inch bar capacity and a 6-inch sub-spindle chuck, enabling simultaneous dual-spindle machining operations. The main spindle delivers 30/20 HP at speeds up to 5000 RPM with an A2-6 nose and 2.44-inch bore, while the sub-spindle provides 15/10 HP at speeds reaching 6000 RPM. The machine accommodates 60 tools total with a swiveling H1 live tool spindle offering 50-12,000 RPM capability and 225-degree rotation, supporting tool diameters up to 5.12 inches and lengths of 7.87 inches. The Y-axis provides 7.87 inches of off-center milling capability, complemented by rapid traverse rates of 1575 ipm (X/Z), 1023 ipm (Y), and 787 ipm (W-axis). Travel distances include 19.69 inches (X-axis), 31.5 inches (Z-axis), and 31.89 inches (W-axis sub-spindle), with a 40.55-inch distance between spindles for maximum part flexibility. Both main and sub-spindles feature 0.001-degree C-axis indexing precision, while the H1 swivel head maintains 0.001-degree H1 indexing accuracy. The machine can machine parts up to 23.62 inches in diameter, making it ideal for complex, multi-featured components requiring integrated turning, milling, drilling, and secondary operations without part handling.
