V760EX/V920EX: This Okuma vertical lathe provides the maximum in floor space productivity.

V920EX: The V920EX increases productivity by providing stable machining of thin and odd-shaped workpieces.

Motor case: High efficiency and stable machining with ATC integration. (V920EX)

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

Large machining area can accommodate a wide range of applications

Large machining area achieved with small footprint. Sufficient space (maximum swing: ø800 mm/V760EX, ø1,000 mm/V920EX) for chucking of odd-shaped workpieces is also provided, meeting a wide range of customer machining needs.
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.
The features of vertical lathes provide for highly accurate, stable machining

Since the adhesive weight of a workpiece helps clamp it to the chuck's reference surface.
This prevents workpiece warp, and accommodates thin, large-diameter, or heavy workpieces.
With fixtures for odd-shaped components, manual part load/unload (without holding the part in place) is also easy.
Machining capacity (actual data)

Process-intensive machining with powerful milling: More powerful, can use greater number of tools; V760EX

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.

Innovative shop floor productivity in many types of production

High productivity with 2 roles by 1 machine (2SP-V760EX, 2SP-V920EX)

The 2-spindle spec 2SP-V760EX, 2SP-V920EX 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 right-left structure also enables stable machining that is unaffected by the machining vibration of the other spindle.

Compact lines that minimize robot travel can be built.
