Manufacturer: OKUMA
Series: MULTUS B Series
Type: Horizontal Lathes, Turn Mill Machine

The MULTUS B400II is the ultimate fusion of turn-mill operations, with lathe, vertical or horizontal machining center and material handling operations consolidated into one 10-12 inch chuck class machine. This multi-tasking CNC machine performs process-intensive machining for shorter deliveries, while making more effective use of floor space. With fewer setups, work in process is drastically reduced and machine utilization is greatly increased.

The MULTUS B400II has a 225° B-axis range with 6,000 rpm H1-milling spindle with dual function (L/M). The H-1 dual function spindle head utilizes CAPTO-C6 tooling and has an 18/13 hp PREX milling motor spindle [opt: 10,000 rpm – 27/19 hp]. The base offering has 40-tool ATC, with an optional 60-tool ATC available. The H1-turret has a 0.001 degree B-axis and compound motion Y-axis for machining flexibility. The main spindle is equipped with a full contouring C-axis.

Thermo-Friendly construction assures high accuracy, even in the most complex applications, and the optional W version with sub-spindle allows a part to be handed from one spindle to the other. The MULTUS B400II is equipped with Okuma’s THINC-OSP P300S control that is designed with ease of operation in mind. With single-mode operation and superior graphics, novice operators as well as professional machinists will experience a smoother, more effective way of producing parts.
