Multitasking Expands Potential

The flexibility of multitasking machines improves accuracy and decreases total cost of ownership in a more compact footprint.

Product Detail

Our MULTUS U4000, equipped with B-axis, is a multitasking 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.

Now you can create contours, perform deep drilling and gear cutting, and do simple turning and milling tasks—all in one machine.

Familiar programming methods from both lathe and machining center disciplines blend easily thanks to our OSP-P300 control.
