High-Rigidity, High-Precision Large Vertical Lathes

vertical lathes, machining flanges,

Mori Seiki Co., Ltd. introduces its NVL1350 Series of high-rigidity, high-precision large vertical lathes. The NVL Series machine is a large vertical lathe with a maximum turning O.D. of 1,600 mm. The NVL1350T has turret head specifications, and is specialized for machining flanges. The NVL1350MC is equipped with an ATC, and handles milling with a wide work envelope. Mori Seiki has developed the NVL Series in response to increasing demand from the aircraft, construction machinery and energy industries for a machine capable of handling large-diameter workpieces. The NVL Series machine reliably meets customers' needs with its (1) high-rigidity, (2) high precision, (3) improved productivity, (4) outstanding
operability, (5) MAPPS IV and (6) compliance with safety standards.
(1) High rigidity
T type: The stroke is designed to suit large-diameter flanges. High rigidity is ensured with the low machine
height.
MC type: The rotary tool spindle is equipped with a built-in motor, large-diameter bearing and ORC
(Octagonal Ram) with a distance between opposite sides of 380 mm, ensuring rigidity. The Z-stroke can
be extended by positioning the cross rail at arbitrary positions on the ZB-axis. Since the cross rail moves
up and down on the ZB-axis according to the workpiece height, ram overhang can be kept as short as
possible during machining.
Both the T and MC types use slideways for all axes to minimize vibration during machining.
(2) High precision
T type: The turret head offers stable, long-term machining.
T/MC types: The twin ball screws drive the Z-axis, offering more precise positioning control. In addition,
in-machine measuring system capable of measuring the workpiece diameter is available as an option to
offer higher precision machining. The X-axis scale is also provided as standard to improve machining and
positioning accuracy.
(3) Improved productivity
T type: The stroke is designed to suit large-diameter flanges in response to the market demand. Since the
machine width, height and installation area are kept compact compared to other companies' machines in
the same class, productivity per unit area has been increased.
MC type: The ATC double arm drastically reduces ATC time. This makes the NVL1350MC different from
other companies' machines in which a ram travels to a magazine and directly changes tools. In addition,
hydraulic chuck specifications, 2-station shuttle type APC and rack magazine specifications are available as
options so that customers can choose the best specifications to suit their machining.
(4) Outstanding operability
T type: The operator can change more than one insert in only one indexing through the window that is
placed at the setup area and opens wide. There is no need to go inside the machine for insert change.
In addition, the turret is designed for easy holder change operation using a crane, and its holder mounting
surface can be indexed horizontally.
T/MC types: Since the internal steps can be flipped up, the inside of the machine can be cleaned easily.
The floor level difference between the internal and external steps is eliminated so that the operator will not
lose his/her footing when going in and out the machine. In addition, the chip conveyors placed on the both
sides of the table reliably discharge chips outside of the machine.
(5) MAPPS IV
The MAPPS IV high-performance operating system has been installed in the NVL1350 Series' operation
panel. The automatic programming software offers flexible machining according to customers' workpieces.
The NVL1350 Series machine offers outstanding operability with the industry's largest 19-inch display,
customizable soft-keys placed on the right and left sides and a PC-type keyboard.
(6) Compliance with safety standards
The NVL1350 Series complies with safety standards of the respective countries around the world. (CE
marking, UL, ANSI and other standards)
