The Okuma MULTUS B550 is a multi-function turning center including left and right spindles, milling spindle and automatic tool changer. The MULTUS 550 has a broad scope of machining functions and is the embodiment of power, speed, and process flexibility. Complete the work in one set-up and with tools to spare in the ATC.

The MULTUS B550 has a 240° B-axis range with 5,000 rpm H1-milling spindle with dual function (L/M). The standard H-1 dual function spindle head utilizes CAPTO C8 tooling and has a 50/30hp VAC milling motor spindle [opt. 10,000rpm]. The base offering has 40-tools available via the ATC [optional 80 & 160 tools]. The H1-turret has a 0.001 degree B-axis and traveling column Y-axis for machining flexibility.

Familiar programming methods from both lathe and machining center disciplines blend easily on the MULTUS thanks to the Okuma THINC®-OSP control, giving advanced functions such as total “Collision Avoidance System” as standard. The advantages of the Okuma absolute encoders handle the control of X and Z, the C1, C2, B, Y and W axes without the need for re-zeroing.
