Okuma double-column machining centers with highly rigid and accurate construction Stability and high-accuracy from the spindlehead ways A ram-type spindlehead for super rigidity With a cross section of 350 x 350 mm (13.78 x 13.78 in.) there's enough rigidity in the square ram-type spindlehead to handle any horizontal cut. Big parts machining expertise. This machine was engineered with Okuma’s field-proven experience of building in exceptional power, rigidity, and smooth operation to assure close tolerances over time and high production. The shudder free design means heavy-duty face milling...

All kinds of shapes can be machined under the best conditions with the abundant variation of attachments. Many different processes can be performed continuously in auto operation with the auto tool changer (ATC) and auto attachment changer (AAC), greatly increasing productivity. For oil hole, air hole, thru-spindle coolant, oil mist, and dual contact specifications for each spindle (some specifications not available). One ATC arm performs the changes for both the horizontal and vertical spindles. And with the next tool brought to the standby position during a machining operation, the actual...

I Many functions for a wider range of applications The Okuma NC makes it all possible. Things impossible on non-NC machines like User Task for example, are programmable like on a PC; making for a tremendous range of machining center applications. ■ Geometric change (Optional) 2 Programmable mirror image Mirror image operations can be command programmable as well as handled by switching. Using the points commanded by local coordinates, the drawings produced by a part program can be enlarged or reduced with this function. ■ User Tasks Variables can be used with arithmetic and branch commands...

Spindle speed • Maximum non-adjacent tool size This is the maximum tool size when there are no tools on either side of a tool. * Note: Commercially available milling chucks may interfere with ATC arm and other _ _ , tools. Prior to use, confirm size dimensions with the tool manufacturer Note: Tools with a tool mass moment of 29.4 N-m or more cannot be used. With tools of 19.6 N-m or less, ATC can be used with high-speed operation. ■ Optional Accessories and Optional Specifications ■ Working ranges [When using an L150 extension head, a 90° angular head, and a 300-mm (11.81 in) tool] Unit: mm...

I With revamped operation and responsiveness— ease of use for machine shops first! Smart factories implement advanced digitization and networking (IIoT) in manufacturing to achieve enhanced productivity and added value. The OSP has evolved tremendously as a CNC suited to advanced intelligent technology. Okuma’s new control uses the latest CPUs for a tremendous boost in operability, rendering performance, and processing speed. The OSP suite also features a full range of useful apps that could only come from a machine tool manufacturer, making smart manufacturing a reality. Smooth,...
