MULTUS U4000

Manufacturer: Okuma
Series: MULTUS U Series
Type: Horizontal Lathes, Turn Mill Machine

The MULTUS U4000 is a multi-tasking machine with an automatic tool changer and optional sub-spindle and lower turret. This 8 to 10-inch chuck class machine has a broad scope of machining functions and is the embodiment of power, speed, and process flexibility. 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. Familiar programming methods from both lathe and machining center disciplines blend easily thanks to the Okuma THINC-OSP®-P300 control, giving advanced functions such as Collision Avoidance System as standard.
