NT Nurse Ⅱ
"NT-Nurse II", "NT Work Navigator" and "Overload
detection/ Airbag" were developed to facilitate
programming and set-up, to reduce fixture costs
of complex parts, and to reduce production
stops.
Less Fixtures! Less Set-up! Less Skills!
ACTIVE SAFETY
N a k a m u r a - T o m e S a f e t y T e c h n o l o g y
Overload detection* PASSIVE SAFETY
● Avoid a crash before it
happens!
Material recognition function (G310/
G312) can be used not only to avoid
collisions, but also to optimize the
face turning process for forgings that
have different lengths. In addition, it
is also useful for part-loading status
confirmation, machining datum shift,
and distinguishing different parts.
● Fixtures no longer necessary
Parts are getting more and more complex.
It is necessary to recognize irregular raw
part geometry before machining.Coordinate
recognition of raw part geometry, which is an
essential tool for milling, can be realized with less
cost, less labor and more ease.The measurement
tool is a round bar, whose contact with the part
triggers the coordinate values to be recorded in
the CNC control. This is possible thanks to torque
control technology of servo motors. In addition
to eliminating the need for highly complex fixtures
for chucks and stocker pallets, the cost of
positioning parts can be dramatically reduced.
● All-in-one Software package!
NT-Nurse is software that provides the
operator with user-friendly environment
for operation, programming, and
production on the machine. Among vital
features are coordinate recognition (a
must for multi-tasking), direct chucking
to prevent positioning error during
transfer, and perfect synchronization of
the left and right hand spindles. Other
features include the load monitor for
detecting tool breakage and tool wear,
tool life management, operation condition
monitoring, in addition to many other
features to simply programming, set up,
operation, and production, all offered in
one single package.
● A security feature to rely on
when the worse happens
When unavoidable human error results
in a collision, the servo drive detects
overload and drastically reduces the
impact on the machine by reversing
the slide movement direction within
less than 8 milliseconds.
In addition to minimizing damage
of the first impact*, fears that the
tool will move to the next program
block and cause a second impact,
are reduced to zero. This standard
feature is available on the X, Z, Y, C
and B-Axes.
Not available
available
* This feature does not mean zero impact.
Arbitrary Axis Torque
Limit (G359)During cut off and part transfer from left
to right, closing the right hand side chuck
may cause overload on the right hand
spindle servo axis (B2-Axis), resulting
in a servo alarm. By controlling the B2-
Axis motor torque in a range between
20 and 100%, this feature prevents the
servo motor thrust force from exceeding
a certain value, by slightly moving the
B2-axis when it is subjected to a certain
load, thus preventing cut-off tool insert
breakage and overload servo alarms.
Deep Hole Rigid Tapping CycleStep feed rigid tapping cycle is useful for
difficult-to-machine materials and deep
holes. Regarding the tapping tool retract
amount, it is possible to choose between
two patterns.
Less Control LimitationsContrary to previous control limitations,
rigid tapping and polygon machining (option)
are now possible on either spindle with
upper or lower turret. Rigid tapping is a
standard feature.

Operator full support through easy operation and reliability
Index OverrideTurret speed can be adjusted with the
feed override rotary switch from 0 to
100% during indexing in automatic or
manual mode. This can be used during
fully automatic operation to reduce turret
speed or even bring it to a halt when
necessary.
Jump Programming(G411)For machines equipped with a gantry loader
or a bar feeder, restarting operation after
an interruption, is significantly improved.
Even if the operator has to stop and reset
the machine in the middle of automatic
cycle, there is no need to remove all the
parts from the chucks or gantry hands
to restart operation. The part status
displayed on the NT Nurse screen, is used
to restart the program, which depending on
part machining condition (raw, half-finished
or finished part), jumps to the appropriate
program block and re-starts from there.
Thanks to this feature, programming of
machines with a gantry loader has become
drastically simplified, eliminating the need to
divide each machining program into several
sub-programs.

A machine management feature, that contributes to drastic reduction of set-up time.NT-Nurse provides a user-friendly environment to achieve the best production results. Among NT Nurse features are the Load Monitor for monitoring tool
breakage and tool wear, the Soft Work Pusher for accurate parts transfer, as well as several other features to prevent errors and facilitate production.

●Machining process (conversational) function・Complex machining processes created with minimum key strokes
・Best guidance for Nakamura-Tome multitasking machines
・Smooth programming without confusion
A programming system for creating NC programs (ISO/EIA G-code programs) easily. Among its features are: creating machining
cycles (conversational function), cutting, copying, pasting and moving already-programmed machining processes, setting waiting
M-codes, as well as simulating NC programs using tool path or solid models.
●Process editing functionA function that automatically recognizes and extracts the name and order of all machining
processes, then displays them in a table layout. Machining processes can be moved, copied
or swapped easily. In addition, waiting M-codes can be added with the click of a button.
