Summary

The Okuma MULTUS B300II is a CNC multi-tasking turn-mill center designed for process-intensive machining combining turning, milling, and material handling on a single platform. Its B-axis head, compound-motion Y-axis, and full-contouring C-axis enable complex part manufacturing with reduced setups. Key differentiators include a 225° B-axis range, CAPTO-C6 tooling, dual-function spindle head, and options for automation and multi-tool storage.
