Okuma MULTUS U4000

MULTUS U Series | MULTUS U4000

The MULTUS U4000, an 8-10 inch chuck class machine, is the embodiment of efficiency and process flexibility with an automatic tool changer, optional sub-spindle and lower turret and a variety of machining functions. With this machine, you can complete the work in one setup and with tools to spare in the ATC.

The MULTUS U4000 has a 240° B-axis range with 12,000 rpm H1-milling spindle with dual function (L/M). The H1 dual function spindle head utilizes CAPTO C6 tooling and has a heavy duty 30 HP (intermittent) milling motor spindle. The base offering has 40-tools available via the ATC with an option for 80 tools. The H1-turret has a 0.001 degree B-axis which is provided by a traveling column-type Y axis feed, providing powerful Y axis machining over the range of 11.81 inches. Both the left and right (optional) spindles are equipped with a full contouring C-axis, and the optional lower turret provides additional capability for increased throughput and process balance.

The Okuma THINC®-OSP-P300 control blends familiar programming methods from both lathe and machining center disciplines, giving advanced functions such as “Collision Avoidance System” as standard.
