7. CONNECTION OF THE SPINDLE TO THE BRUSHLESS MOTOR
CAUTION
Make sure your hands and all interlocking parts of the Spindle and brushless motor are clean
before connecting the Spindle to the brushless motor. This is critical in preventing contaminants
from entering the Spindle or brushless motor.
Align the thread on the front end of the brushless
motor and the rear of the Spindle, and turn the
Spindle clockwise. If the drive shaft of the brushless
motor does not engage properly to the drive dog
on the Spindle, it may only turn aprroximately two
threads before stopping.
DO NOT FORCE THEM TOGETHER. Loosen
the Spindle from the brushless motor, rotate the
Spindle shaft by hand then re-try. The drive shaft
and the drive dog must be fully engaged. When
fully engaged, secure the brushless motor and
Spindle using the provided 27mm wrench (Fig. 2).

9. CHANGING THE TOOL
CAUTION
WARNING
Do not open and close the collet while the brushless motor is running.
・
When the air is supplied to the inlet joint of the Spindle, the tool will be pushed out by
exhausting the coolant air of
brushless
motor from the edge of Spindle. Be careful not to be
damaged to the tool or be injured.
・Use the air on-off valve through which the air can be exhausted. Do not use 2 way valve,
because the 2 way valve is not echausted and the collet is not closed.
・Do not open and close the collet before the tool is not installed. Because this will cause damage
to the collet or loss of precision.
8. CONNECTION OF AIR HOSE AND AIR SUPPLY
Securely connect the air hose to the brushless motor and air line kit to avoid accidental
disconnection and injury to the operator during use.
CAUTION
①
Connect the provided ȭ6mm Air
Hose
with lter and 3-way valve to
Air Inlet Joint shown in Fig. 3.
②Supply clean air from air
compressor through air lter or air
dryer to the 3-way valve at the set
air pressure : from 0.55 - 0.6MPa
(79.8 - 87psi).

①Stop the motor (Or check if the motor is stopped).
②Supply air pressure: from 0.55 - 0.6MPa (79.8 - 87psi) to Air Inlet Joint through 3-way valve. Then, the chuck
will be opened. At the same time, the tool is pushed out by the air exhaust for the coolant of motor. So, need
the tool holder not to be damaged to the tool.
③Replace the tool.
④Exhaust the air through 3-way valve. The collet will be closed and the tool can be xed.
WARNING
①The Spindle is not a hand tool. It is designed to be used on CNC machines or special purpose
machines.
②Do not touch the cutting tool while it is running. It is very dangerous.
③Wear safety glasses, dust mask, and use a protective cover around the Spindle whenever the
Spindle is rotating.
④Never connect, disconnect or touch the Power Cord Plug or Motor Cord Plug with wet hands.
This may cause an electric shock.
⑤Never operate or handle the Spindle and brushless motor until you have thoroughly read the
Operation Manuals and safe operation has been conrmed.
1)To prevent injuries / damages, check the Spindle, brushless motor and cutting tool for
proper installation, before operating the Spindle and brushless motor.
2)Before disconnecting the Spindle and brushless motor, always turn the control power off
and turn the compressed air supply to the CONTROLLER off. Then it is safe to remove the
Spindle and brushless motor.
⑥When installing a Spindle to a xed base, make sure the xed base is grounded in order to
avoid the risk of an electric shock.
⑦When installing a tool, tighten the collet correctly and check again the collet before use. Do not
over-tighten the collet. This may cause damage to the spindle.
⑧Do not open and close the collet while the brushless motor is running.
⑨Do not use bent, broken, chipped, out of round or sub-standard tools, as this may cause them
to shatter or explode. Tools with fractures or a bent shank will cause injury to the operator.
When using a new tool, rotate it in a low speed and increase speed gradually for safety.
⑩Do not exceed the maximum recommended allowable tool speed. For your safety, use speeds
below the maximum allowable speed.
⑪Do not apply excessive force. This may cause tool slippage, tool damage, injury to the operator
or loss of concentricity and precision.
CAUTION
①Do not drop or hit this Spindle, as shock can damage to the internal components.
②Do not connect this Spindle to the redutcion gear. This may cause collet breakage by overload.
③Be sure to clean the collet, the inside of the spindle before replacing the tool. If ground
particles or metal chips stick to the inside of spindle or the collet, damage to the collet or
spindle can occur due to the loss of precision.
④When cleaning a Spindle, stop the brushless motor and remove debris with a soft brush or a
cloth. Do not blow air into the end of spindle area (refer to section " 6 - 2 Outside View ") with
compressed air as foreign particles or cutting debris may get into the ball bearing.
⑤Always clean the tool shank before installing the tool in the spindle.
⑥
When sizing the correct collet size to the tool shank diameter, a tolerance of +0 ~
-
0.01mm is
strongly recommended. A tool shank within the +0 ~
-
0.1mm range is mountable, however, this
may cause poor concentricity and or insufcient tool shank gripping force.
⑦Select suitable products or tools for all applications. Do not exceed the capabilities of the
Spindle or tools.
⑧Do not stop the supplied cooling air to the brushless motor during operation of the machine.
Removing the air pressure from the brushless motor causes a loss of purging, allowing the
Spindle to ingest coolant and debris. This will cause damage to the Spindle.
⑨Carefully direct coolant spray directly on the tool. Do not spray directly on the Spindle body.
If large amount spray directly on the Spindle, it may cause excess load of the Spindle rotation
with loss of durability to the Spindle.
⑩Stop working immediately when abnormal rotation or unusual vibration are observed.
Immediately, please check the content of section " 14. TROUBLESHOOTING ".
⑪Always check if the tool, collet, connection hose and supply air hose for damaged before and
after operating.
⑫If the collet show signs of wear or damage, replace it before a malfunction or additional
damage occurs.
⑬After installation, repair, initial operation, or long periods of non operation, please refer to
section " 12. BREAK-IN PROCEDURE " detailed in Table. 2. When checking the Spindle, no
vibration or unusual sound should be observed during rotation.
⑭Do not disassemble, modify or attempt to repair this Spindle. Additional damage will occur
to the internal components. Service must be performed by NSK NAKANISHI or an authorized
service center.
⑮When using this Spindle for mass production, please consider the purchase of an additional
Spindle to be used as a back-up in case of emergency.
RECOMMENDATIONS
Please set the cutting tools to minimize the overhang amount. 13mm is the maximum amount of
overhang to maintain high accuracy and safety.
