Vertical Turning Lathes V760EX 2SP-V760EX

Stable machining of large-diameter workpieces with a compact machine body

Large machining area can accommodate a wide range of applications

The V760EX provides a large work envelope with max cutting diameter of ø760 mm and height of 770 mm while maintaining a small footprint. This is large enough even for odd-shaped components (max swing: ø800 mm possible) to accommodate a wide range of applications

Stable machining achieved even with difficult-to-chuck thin, large-diameter workpieces and unbalanced, odd-shaped components.

Gives both higher machining capacity and better accuracies

Advanced, highly rigid construction enables powerful and very accurate machining

A rock-solid rectangular column is firmly secured to a rigid base with excellent damping performance. Minimal tool-to-column guideway distance assures the rigidity needed to withstand heavy-duty cutting loads. Moreover, the box ways for the X and Y axes help to achieve heavy-duty cutting of big components at high accuracies.

Highly rigid structure with column fixation and saddle movement

Process-intensive machining with powerful milling

More powerful, can use greater number of tools

Turning, drilling, end milling all done on a single machine to accommodate a wide range of applications. A much more powerful milling tool spindle than on previous machines enables more powerful cutting and a wider range of process-intensive machining. The turret minimizes interference with neighboring tools so that millling tools can be attached in all 12 locations.

Applications from turning to milling can be done with a single chucking, reducing the work in progress storage space and between process waiting times.
Chucking error during workpiece installation can also be eliminated for higher machining accuracies.

Okuma's Intelligent Technology reduces operator burden

Manageable Deformation—Accurately Controlled Thermo-Friendly Concept

Machining accuracies change significantly due to temperature changes around the machine, heat produced by the machine and heat produced in machining. The Thermo-Friendly Concept adopts the unique approach of “accepting” these temperature changes to provide highly accurate machining in normal factory environments without special equipment or measures to counter temperature changes.

Machining dimensional change over time: Less than: ø8μm

Cutting condition search Machining Navi L-g (Optional)

Varying the spindle speed in accordance with the best amplitude and period makes it possible to suppress chatter during turning operations. Tool life can be extended and machining time reduced with use of the optimum cutting conditions, producing significant effects in drilling/boring bar, threading, and grooving applications.

Innovative shop floor productivity in many types of production

High productivity with 2 roles by 1 machine (2SP-V760EX)

The 2-spindle spec 2SP-V760EX combines a standard R (right) machine and reverse structure L (left) machine and is operated with a single controller. This gives the maximum productivity with the minimum floor space by shortening lead times and cutting down on intermediate work in progress.

The separated left/right structure also enables stable machining that is unaffected by the machining vibration of the other spindle.
