Rigid and Precise CNC Lathe NL SERIES 
NL 1500/NL2000/NL2500/NL3000

The millíng mechanísm on conventional lathes generates a great deal of heat and víbration due to the large number of parts involved, including the motor and gear belt. The NL Seńes, however, features the industry's first BMT. This revolutionary design minimízes heat generation and vibration while elíminating transmission losses. The new design increases both machiníng accuracy and cutting performance.

In order to enhance the milling function, it is essential to increase the rigidity of the rotary tool holders. The NL Seríes rotary tool holders have a broader grip compared to conventíonallathes. By raising attachment precision we have vastly improved rigidity.

Comparison of rotary tool holder rigidity
With conventional lathes, chattering occurred when the depth of cut was increased. The NL serìes, however, is equipped with rotary tool holders with
improved rigiılity, allowing deeper cutting than before.

Super-rigid rotary tool holders
Taking a hint from coupIings, which are praised for their high
repeatability, we developed a very rigid rotary tool holder.

High-performance rotary tool spindle
A DDs motor that has no gear belt is used for the rotary tool spindle, delivering high-speed, high-efficiency machining.
DDs: Direct Dríve spindle

Turret variations
Quick-change type turret head (VDI) oá
Turret is equipped with quick-change specifications for VDI tools. Tool attachment time is dramatically reduced.

Capto-compatible holder
The Coromant Capto modular tooling system, wìth much faster tool-changing  time than conventional machines.

20-station turret head 
(NL1500, NL2000)
A 20-station turret for workpieces which require many machining processes, or for various types of workpieces.

10-station turret head (NL3000)
Equipped with the bolt-fastened type, 10-station turret from the NL3000.
The ultimate in turning
Improved tool tip rigidity
By íncreasíng the rígidity between the spindle and tool tip, tool típ vibration has been minimized, achieving a high-quality cutting
surface during turning. At the same time, tool tip vibratíon control also contributes to longer tool life.

Conventional machines create a pattern on material due to the amount of vibration the tool tip generates. If you do the same machining with the NL Series, the high machine rigidity shows in the cutting surface.

Rigid basę
Ultra-high rigidity structure
We have a new design for the basic structure: the spíndle, saddle and taílstock. Thís new design ensures consístent rígidity. The result ís a level of rigidity that has not been seen
before, wíth increased stabílity due to the broad bottom face.
Torsionally rigid
Bed torsion rigidity
Dramatically better bed torsion rigidity compared to conventional machines has been achieved through static analysis.
Broader guideways
The slideways are 30% wìder than those of conventional machines and are the largest in the class. We have achieved an unknown level of stability not only in turning work but also in milling work.

Highly rigid spindle
The axis rigidity of the headstock and its mounting have been improved by changíng the shape of the headstock and increasing the thíckness of its parts. The diameter of the beańngs has been increased. Thís allows better spindle rigidity while enlarging the through-hole diameter.

Thermal isolation
Designed to eliminate all heat
The most prominent feature of the NL Seríes is said to be the elimínation of the adverse effects of heat. In order to raíse the continuous machíníng precísion of lathes, 95% of whích ís said to be taken up by cuttíng tíme, we at Mori Seíkí have come up with the concept of total heat elimínatíon.

Previous model
It is commoп to find the oiI cooler — a major source of heat —located right next to the spindle in conventional machines. As a result, the headstock is affected adversely by that heat.

NL SERIES
Placing the oil cooler behind the machine removes that heat source from the headstock. The machine is designed so that the exhaust from the oil cooler doesn't come in direct contact with the machine.

Spíndle cooling
We have redesígned the spíndle, whích ís the greatest source of heat, to employ a
uniform-heat constructíon that maíntaíns an equal temperature all around the spindle. The main spindle unít is protected from ríses ín temperature by the spiralíng oil jacket located all the way to the back side.

Inverter-type oil cooleг
An inverter-type oil cooleг with very accurate temperature regulation has been used.

Ball screw shaft cooling (option)
As an option to íncrease machiníng accuracy even further, we have províded ball screw core coolíng. (X-axis only)

Variations
We want everyone to use the new standard in CNC lathes.
Moń Seiki's NL Seńes has machines in four classes for different workpiece sizes and síx types to best match the level of thecustomer's machining and process integration. Wíth a total of 36 variations, you are bound to fınd one right for you.

NL3000
Y-axis specifications
We also independently developed a powerful platform for maximizing performance in the Y-axis specifications. Thís has achieved rigidity between the spíndle
and the tool tip that exceeds that of conventíonal two-axis lathes
Linking the X-axis and a virtual axis creates the Y-axis movement. The axis unit has been
downsized to lower machine height.

On a conventionai turning center, polar coordinate interpolation is used for tool motion controI during grooving and contouring, as illustrated in the left figure. 1n this control mode, however, the x-axis travel direction is reversed at points "a", the intersectìons between the workpiece center line and the profile to be machined.
This reversal changes cutting conditions and subsequently effects profile accucacy. Machining with Y-axis control, on the other hand, is free of such changes and ensures a high level of profile accuracy.

Choose from S-type, which allows both-face continuous machining, SMC-type which offers consistent machining from turning to secondary machining and back face machining thanks to its combination of headstock 2 and rotary tools, and SY-type, which achieves superior multi-axis machining with the additional Y-axis.
The NL Series comes standard with a new feature — a highly rigid digítal tailstock
driven by a servo motor. This drastically reduces setup time. (New standard feature
does not apply to S, SMC and SY types.)

Fewer steps requíríng operatíon of the taílstock
The operator is freed from the hassle of having to lock the tailstock when
changing to a workpiece of a different length, connecting it to the turret, etc.
■ Operatíng time reduced
With the conventional hydraulic system, changing the tailstock spindle settIngs was
inconvenient, so there was a limit to how much operating time could be reduced. A digital
tailstock with vańable feed speed control allows separate speeds to be set for approach
and engagement, reducing the operating time of the tailstock spindIe by over 20%.
■ Varíable pressure control using program instructíons
With a hydraulic tailstock spindle, thrust is controlled indirectly using a hydraulic pressure
meter, so if you use different machine models, you will get different thrusts even if the
same pressure is set. With a digital tailstock, however, the thrust is measured directly,
so the workpiece engagement is done accurately, raIsing machir ing precision.
■ símple operatíon using MAPPS III
Approach positìon, retract position, re-chucking and more can be done simply and
easily from the MAPPS III screen. Besides being able to handle a variety of different
workpiece types, it can also work with M-code thrust selection as a standard feature

More applicatíons
With a servomotor for positioning, the digital tailstock has outstanding functionality. It can also be used for certain types of machining (e.g., drilling, boring) of the center of the workpiece end face.

Distance between centers 2000 type, 3000 type (NL3000)
In order to machine long workpieces wíth high speed and high precision, we have added a high-rigidity bed and special functions and equipment for machining long workpíeces. It ís the definitíve bar work machine, eliminating
all compromise.

NL SERIES
Ever since our first machíne tool rolled off the production line ín 1968, we here at Moń Seíkí have continued to make CNC lathes that are praised by customers everywhere. Over those 35 years, we have released around 100 models. We can say with
confidence that we believe every síngle one was an ímprovement on íts predecessor. So Moń Seíki has been able to create a new generatíon of CNC
lathes, a lathe that moves the world. By revíewing the structure of everу feature, by confronting the pгoblem of heat generatíon, by reflecting on a
product which íncorporates all the customers' many demands. Through uncompromísing
development, we have achieved previously unheard of levels of ńgídíty, accuracy and reliabílity. Our efforts have created our newest line, the NL Seńes.
These new machines are high-rígidity, híghprecisίon CNC lathes and set the new standard in
"common sense" machining for a new age.

By employing a super-rigid construction for the NL S and equipping it with a BMTTM (Built-ín Motor Turret), it is able to deliver cutting equal to that of machines one class above. This contributes to productivity.

Productivity
What are the differences in machining time, production volume and sales between previous models and the NL Series?
We have included a machíning simulation comparing the NL Series to previous models, so take a look at the outstanding productivŕty of the innovative NL Seńes for yourself.

N Series cost structure comparison
This is a comparison of costs between the N series and conventìonal machines, assuming the same sales (i.e. production). Even if the price were set at 20% higher, the
N series, with its advantages of shorter machining time, the ability to control personnel costs, tool life and power consumption, allows you to double your profits.

Minimizing machine down time. In our constant effoıt become the most trusted machine tool company in industry, we design Mori Seiki machines with maintenance and reliability in mind.

Convenience
The NL Series has been designed with the operator first and foremost in mind, with innovations included throLighout the machines to increase convenience.

Broader field of vision
The new design includes a vertical front door and a window closer to the operator. The broader field of vision allows the operator to view the machine interior without having to stoop down. The distance between the operation panel and the machine interior has been shortened, thus reducing eye strain.

Eco-friendly design
Reducing the strain on the environment has become an important task facing companies today. NL seńes have been designed with environmentally frìendly functions to make this task easier.
The new functions focus on reducing lubricant and electricity consumption. This focus fills customer needs at reduced costs.

Automatic machine light functíon
If the operation panel is not touched for a certain amount of time, the interior light turns off. This saves energy and lengthens the life of the machine lights.

Function to reduce power consumption during standby
The amount of electricity consumed in standby mode has been reduced.

Automatíc sleep function
If the keyboard is not touched for a certain amount of time and NC operation is not being performed, power is cut off to the servo motor, the spindle, the coolant pump and the chip conveyor, thereby saving energy.

MAPPS III for CNC Lathes
The CPU's processing power has been improved, with many functions whích dramatically
reduce the time for programming and setup. The 3rd generation NC unit MAPPS III is
designed for productivity. A new interface connectíng person and machíne.
