Flexible machining from all directions
Tough cutting in entire Y-axis rangeWith the ideal, large work envelope for lots of milling of complex parts. The class best Y-axis travel is fully utilized with a highly rigid traveling column, for powerful cutting along the entire Y axis. |
Wide B-axis swing: 240°The wide 240-degree swing of the B axis spindle allows it to have equivalent machining areas for both the main and opposing spindle. With the NC-B axis, roller gears are used to achieve “0” backlash during B-axis drive, and highly accurate 5-axis machining. |
 |
 |
Superb C-axis positioning accuracy: 0.0001°control
As an option*, a highly accurate C-axis function is used for both the main and opposing spindles. This will support end-users requiring very accurate machining of component shapes that are quite complex.
Moreover, heavy-duty milling, with a solid retention mechanism, makes possible applications that require both high accuracy and high efficiency.
* Standard in certain markets.

Achieves process-intensive machining beyond the framework of multitasking machines
Sloped axis turning
Turn-Cut
Turn-Cut is an original Okuma technology that enables turning on a milling spindle. The circular turning of the feed shaft and the spindle indexing angle are simultaneously controlled so that the tool edge is always facing the center of the milling spindle circular turning.
Sloped axis turning can be done by sloping the B axis. Moreover, machining of any diameter can be done with a single tool. Inside and outside diameter machining that is larger than the maximum tool diameter can be done. In setting cutting conditions, the Turn-Cut Guide (Optional) advises the best turning speed when the diameter and roundness of the machining area are designated.

High accuracy gear cutting with a multitasking machine
Gear Machining Package (Optional)
Gear cutting that previously required complex programming can now be done with ease. With easy programming, simply input the tool type, gear data, and cutting conditions to achieve highly accurate machining, reducing programming time to about one-tenth that of manual input. Process-intensive machining is achieved, including the gear cutting that used to be done on expensive special-purpose machines.
