Introduction
Thank you for your having purchased the machine, favoring our product lines for your use.
This manual contains fundamental information on the machine operation. Please read and fully
understand the contents for your safe machine operation.
In particular , the contents of the items concerning safety in this manual and the descriptions on the
“caution plates” attached to the machine are important. Please follow the instructions contained
and keep them always in mind to ensure safe operation.
The reference record papers on adjusting setting values such as a parameter list are attached to
the machine unit and enclosed in the packing. These are necessary for maintenance and
adjustment of the machine later on. Please keep them safely not to be mislaid.
The design and specifications of this machine may be changed to meet any future improvement.
As the result, there may arise some cases where explanations in this manual could become partly
inconsistent with the actual machine. Please note this point in advance.

3. Procedure of Machine Operation
3-1 At the Time of Start
[1] Turn on the power source switch.
[2] Supply air pressure.
[3] Turn on the power switch of the power
control cabinet.
[4] Press the POWER/STANBY [ON] on the
left corner of themain control panel.
Caution
Main panel and NC unit is sealed type
construction and avoid a mixture of outer
air directly. Therefore, don’t keep open
the door long time of period during power
on.
Check on the display and that fan motors
heat exchanger are started.
[5] Once the Overall screen is displayed,
turn [EMERGENCY STOP] to the right to
unlock it.
[6] Press the POWER/STANBY [ON] on the
left corner of the main operation panel.
(Lamp lights.)
Check a setting pressure of hydraulic unit

[7] Move X and Z axes several times to
lubricate each slide way before starting
operation.
(Pay attention to avoid over travel.)
[8] Press the [ZERO RETURN] .
(Refer to “Procedure of zero return”)
This will return the turret head to the
machine zero point.
[9] Turn on the switch for chip conveyor.
}as fixed value.
Caution
Do not operate the machine with plenty of
chip in the trough of chip conveyor.

3-2 Warming-up Operation of Spindle
Caution
It is important to keep status of bearing in good condition by lubrication, etc., to make
the spindle rotate normally. Sudden rotation of the spindle may cause sticking of the
bearings because of shortage of lubricating oil at the bearing section. To get the best
performance of the spindle function by correct operation, warming-up operation as
below-mentioned is necessary.
Warming-up operation for every starting (30 minutes)
[1] 10 minutes at 30% of the maximum spindle rotation
[2] 10 minutes at 50% of the maximum spindle rotation
[3] 10 minutes at 80% of the maximum spindle rotation
Conduct warming-up operation in the above order, [1], [2], [3]
1 - 16
3-3 Procedure of Zero Return
This function is conveniently designed to return the turret head to the machine zero point in
order of the X- and Z-axis in single-touch operation.
Method 1 of zero return
[1] Make a mode to [JOG].
Move the X- and Z-axis about 100 mm in
the minus direction.
[2] Press the [ZERO RETURN] key.
If a single-touch zero point return
prohibited area alarm is issued, move the
X- and Z-axis until the alarm has
disappeared.
[3] Move a tool head to zero point by rapid
traverse (10% override). The tool head
stops at zero point and a confirmation
lamp of zero point of the axis turns on.
Return the X- and Z-axis to the zero point
in that order.
Method 2 of zero return
[1] Make a mode to [JOG].
[2] If the X and Z axes locate near the zero
point, move it opposite direction (Minus)
from zero point about 100mm.
[3] Press [X+] and [Z+] in that order to return
the X- and Z-axis to the zero point.
[4] Release a finger from the switch after the
confirmation lamp of zero point turned on.
Execute zero point return of each axis by the
operations above.
Caution
1. Execute zero return of axis one by one for safety.
(At first, do it from X-axis.)
2. Pay attention of interference with the tailstock at the time of zero return.
3. The turret head does not move when rapid traverse override is 0 %. Set it to 1 % or
10 %.
4. When rapid traverse override is 1 %, it moves at override of 1 %.
1 - 17
3-4 At the End of Operation
[1] Clean up the machine.
Stop the chip conveyor after all chips
carried out from the conveyor.
[2] Confirm the machine stopped completely.
• Spindle rotation
• Program
• X and Z axes
• Coolant
• Chip conveyor
[3] Press the [EMERGENCY STOP] button
on the main operation panel.
[4] Press power [OFF] button at the main
operation panel and control power off.
[5] Turn off the power switch of the power
control cabinet.
[6] Cut out supply air pressure.
[7] Set the main power switch [OFF].

4. Manual Operation
4-1 Feed of Each Axis
— In case of manual feed —
[1] Press the [JOG] for mode select push
button switch.
You may select the [HANDLE] either.
[2] Set the manual federate rotary switch to
suitable speed.
Move the machine to desired direction by
the manual feed direction push button
switch.
Take a finger off from the switch when
reach to the fixed position.
(The machine moves only when pressing
the switch.)
In case of a feed by the HANDLE, it can
be operated the same about it.
(Example of use)
• Warm up running
• In case of approach near the zero position.
• In case of cutting manually
• Setting work
1 - 19
— In case of the handle feed —
[1] Select the axis by the axis push button
switch.
[2] Fine feed can be done by the manual
handle.
• When select 1/1: One division is
0.001mm
• When select 10/1: One division is
0.01mm
• When select 100/1: One division is
0.1mm
In case of the spindle indexing C axis, the
unit becomes a degree.

4-2 Operating Method of Q-setter
A tool position compensating value can be get easily, since a tool position compensation is
inputted automatically by touching a tool tip to the Q-setter.
In case of the turret rotates, a cursor changes automatically due to a tool face number
correspond an offset number.
[1] Confirm the zero return condition of the X
and Z axes.
If confirmation lamp is not lit, execute
manual zero return.
[2] Make a mode to manual mode [HANDLE]
or [JOG].
[3] Pull out the Q setter
A screen changes to the offset screen
automatically and display the “Q-setter”
and inform a ready of complete condition
of preparation.
Zero return lamp turns on
[4] Call a tool compensation required.
Press the [TOOL INDEX] and
[SELECT] at the same time.

A tool face selected at this moment is
recognized by a cursor position.

[8] When a tool tip touches the sensor by
JOG mode, a compensating value is
inputted automatically. At this time, the
feed rate is fixed, disabling speed
selection.
Caution
If it is executed by operating the
[HANDLE], the accuracy will not be
stabilized. (Reason: When having the tool
nose touch the Q setter, the accuracy is
stabilized by having it touched at a
constant speed.)

When a tool tip touch to the sensor,

[9] Execute a tool tip measurement by touching a tool tip to the sensor twice or so.
Confirm a tool compensation
amount on the screen.
[10] Retract a tool tip from the sensor to safety zone by
[HANDLE] mode. A safety zone is a position which is not
interfered a tool and sensor even if the turret rotates.
When retracting the cutting edge in the [HANDLE]
mode from the beginning, retract it slowly up to about
1 mm. If retracted abruptly in the [HANDLE] mode,
the cutting edge direction may be misconceive,
disabling an entry of a correct compensation value.
[11] Get a compensation amount for the other tool in turn as the same method.
OTHERS
Reference In case of thread cutting tool
In case of thread cutting tool, a tool compensation value of Z value is obtained by the side
of insert as described by Fig. 1 and 2, effective length of thread becomes short by “Width
T” due to position of cutting edge is different. Therefore, get a tool compensation amount
by the Q setter as Fig. 1 then execute incremental compensation input to minus side (In
case of Fig. 2, plus side), so correct effective length of thread can be get as Fig. 3.
The incremental amount you can input at a time is up to 1mm. If it exceeds 1mm, divide the
input into several times, with the amount less than 1mm each time.

How to get a tool compensating amount for a tool
tip may not be touch the Q-setter
A work coordinate system setting should be
done before executing this operation.
A correct compensating amount can not be
found without a work shift operation.
“How to get a tool compensating amount
1.
for a longitudinal direction (Z)”
[1] Call a tool by index the turret.
Select the mode switch either the
[HANDLE] or [JOG].
[2] Call the tool offset screen and
confirm a tool compensating amount
(Z) is zero. Set zero if it is not zero.
Press the [TOOL INDEX]
and [SELECT] at the same
time.
Press F3/TOOL .
Example: In case of T0200
Set the tool (offset) No. 02.
