OKUMA MULTUS U4000-2SW/2000 CNC LATHES

Technical Description

This high-capacity CNC turning center features a robust main spindle with a 12" chuck (A2-11 mount), operating at speeds up to 3000 RPM and delivering 32 kW peak power (22 kW continuous). The sub spindle (A2-8 mount) supports a 10" chuck, with speeds ranging from 38 to 3800 RPM and power output of 22 kW peak (15 kW continuous). Axis travel includes an upper X-axis of 27.36", a lower X-axis of 9.25", and a Y-axis with ±5.91" travel, complemented by a W-axis stroke of 79.69" on the sub spindle. The through-spindle bore measures 5.5", allowing for long bar workpieces. The machine accommodates a maximum machining diameter of 25.59" and a length of 78.74" between centers, supporting large, complex parts. A high-speed milling turret featuring a CAPTO C6 mount operates between 50 and 12,000 RPM, with power ratings of 22 kW (3 min), 15 kW (15 min), and 11 kW continuous, enabling milling and drilling capabilities integrated into the turning process. The tool magazine combines two 40-position carousels, totaling 80 tools, for versatile multi-tool machining. Overall machine dimensions measure 243" long by 121" deep and 120" high, with a substantial weight of 44,000 lbs, reflecting its heavy-duty industrial design. This configuration supports efficient multi-axis turning and milling operations for complex workpieces with high precision and throughput, ideal for aerospace, automotive, and heavy machinery manufacturing requiring simultaneous multi-spindle machining with integrated milling capacity.
