Air Hose Connection; Changing Cutting Tools - Nakanishi E3200 Series Operation Manual

AIR HOSE CONNECTION

11
(1) Insert the provided ø6mm filtered air hose from the AL-0201 air line kit into the inlet joint
[ 7 ] on the front of the control unit. (If you are not using the AL-0201 air line kit make sure
that the incoming air supply is dry, clean air.)
(2) Insert one end of the provided ø3.2mm cooling air hose into the back of the motor.
(3) Insert the other end of the ø4mm cooling air hose into the air output joint [ 8 ] on the front
of the control unit using the provided ø6mm to ø4mm adaptor.
(4) Regulate air pressure between 0.25-0.3MPa.
The system can be set to operate without cooling air. Please see parameter setting
to set this option. Maximum speed is 30,000min
Note : It is not recommended to use the system in this manner for general machining.
This setting is only for light cutting and not for use with coolants.

CAUTION
1. Regulate the air supply between 0.25-0.3MPa. If the air pressure is too low the
control unit will not operate.
2. The cooling air provides two functions, to cool the electric motor and to protect
the spindle from contaminants. If air supply is shut off do not subject the spindle
to direct coolant spray or use in dusty areas.
3. Do not bend the air hose in any sharp bends or pull on the hose this can cause
the hose to break, cut off the air supply or weaken the hose over time resulting in
deterioration of the motor and spindle.
4. Attach the connector cover (provided) for safety, when not using Input/Output
Connector A/B and communication connector.
5. Never supply over the regulated air pressure. There is a threat to damage to the
air detect sensor inside the control unit.
6. The air detect function with the control unit is the detector of the input only.
When damaging to the air hose of the output of the control unit, can't be able to
detect no air supply to the motor spindle.

CHANGING CUTTING TOOLS

12
The spanner size and the cutting tool replacement varies depends on the spindle types. Be sure
to check the operation manual on the spindle or the motor spindle about the details.
(1) Set the provided wrench on the spindle.
(2) Place the provided wrench on the chuck nut and turn it counterclockwise to loosen the
collet and remove the cutting tool. (The first turn will loosen the chuck nut, but the tool will
not release and turning will become stiff. Keep turning through the stiffness and the collet
will open.)
(3) Insert the new tool and tighten the collet by turning clockwise.
Chuck Nut
CAUTION
Never install a collet into the spindle quill without first assembling it in the chuck
nut. Do not tighten the collet without mounting a cutting tool or dummy bur as this
will result in damage to the collet, spindle and chuck nut and make it impossible to
remove the collet.
