“We want to further automate our line.”
“We want to realize a flexible line using
general-purpose machines.”
“We want to have a space saving machine.”
Okuma has just come up with a brilliant answer to
satisfy these requirements for high production CNC
lathes applications. Our LVT300/300-M vertical NC
lathes are innovators for automatic production lines.
The spindle is equipped with a loading function,
so the workpiece can be carried within the machine.
You can install these lathes in narrow spaces: 1.3 m
(4.26 ft) in width and only 3.69 m2 (39.7 ft2) of floor
space. You can build a reliable production line with
quick rapids, excellent thermal stability, and smooth
chip disposal.
Loaders no longer needed.The spindle carries the workpiece.
Automatic and flexible production lines are achieved with a loader function equipped to the spindle
Layout lines can be shortened, namely these lathes can be installed in only 1.3-m widths (4.26 ft) , or 3.69 m2 (39.7 ft2) of floor space.

Loading and unloading by the spindle greatly reduce both the cycle time and space
The vertical spindle itself functions as a loader, gripping a workpiece and moving it horizontally (X-axis) and vertically (Z-axis). Complete on-board automation of chucking and loading not only reduces the cycle time, it also creates a more compact line by greatly reducing the frontage and floor space.
Smooth chip disposal
As the turret is fixed, the cutting point is always constant, and the chips drop down directly without any scattering. Then, the chip conveyor speedily carries the chips out of the machine, and problems with the chips heating are practically eliminated.
Excellent thermal stability that supports continuous machining accuracy
A box type bed based on logically designed construction is adopted, which has little vibration effect as well as little local distortion due to heat. Thermal deformation and long run dimensional change are minimized.
Outstanding machining capability and superior machining accuracy
Rapid traverse marvelously reduces non-cutting time
A linear guide with high reliability and high stability is fully adopted for the spindle guideway. Together with the high-speed turret, it allows you to greatly reduce non-cutting time.
Highly rigid construction means powerful machining
The highly rigid box type bed and large diameter ø250-mm (ø9.84-in.) coupling for the turret provide heavy cutting with the powerful hydraulic clamping mechanism (non-lift).
Milling specification (LVT300-M)
With one chucking, this is the most suitable for multitask machining (turning, drilling, milling, and tapping).
Reliable accuracy from logically suppressing heat and vibration
•Rapid traverse X: 60 m/min (2362 ipm) Z: 30 m/min (1181 ipm)
•Turret rotation 0.18 sec/index (Okuma standard tooling)
Turning example Workpiece material: S45C• Heavy cutting 3 mm2 (0.005 in.2)• Cutting speed V : 100 m/min (3937 ipm)• Cutting depth t : 6 mm (0.24 in.)• Feedrate f : 0.5 mm/rev (0.02 ipr)
• Max. workpiece weight: 20 kg (44 lb) (when using standard chuck cylinder)• Loading/unloading time: 8 sec

To reduce loading and unloading time, this system uses IN and OUT conveyors.
This system which loading and unloading are on one conveyor.
A variety of layouts can be realized, dependingon your process management and factory space.

Hi-G control, TAS-C (Thermal Active Stabilizer–Construction)
As a “machine & control” builder, Okuma makes further strides in machine tool manufacturing with
this superb, control featuring “Easy Operation”. Okuma took a close look at the way machinists
actually operate machine tools, to help them create smoother and more effective ways of producing
parts. Novice operators as well as professional machinists get complete control—and satisfaction.
Moreover, what you want to see and do conveniently come together in a “single-mode operation”.
First, select one of three operation screens.
Then simply touch the screen or press a function key to see and do your job.
