Automatic Tool Replacement Spindle
NR50 -5100 ATC
OPERATION MANUAL
Thank you for purchasing Automatic Tool Replacement Spindle " NR50 - 5100 ATC ". This Spindle is designed
for suited for PCB drilling. The E3000 CONTROLLER, Brushless Motor and Air Line Kit are required to drive this
Spindle. Read this and all the associated component Operation Manuals carefully before use. Always keep this
Operation Manual in a place where a user can referred to for reference at any time.
1 . CAUTIONS FOR HANDLING AND OPERATION
■ Read these warnings and cautions carefully and only use in the manner intended.
■ These warnings and cautions are intended to avoid potential hazards that could result in personal injury to the
operator or damage to the device. These are classified as follows in accordance with the seriousness of the risk.
Class Degree of Risk
A safety hazard could result in bodily injury or damage to the device if
WARNING
the safety instructions are not properly followed.
A hazard that could result in light or moderate bodily injury or damage
CAUTION
to the device if the safety instructions are not followed.
WARNING
① The Spindle is not a hand tool. It is designed to be used on CNC machines or special purpose
machines.
② Do not touch the cutting tool while it is running. It is very dangerous.
Wear safety glasses, dust mask, and use a protective cover around the Spindle whenever the
③
Spindle is rotating.
④ Never connect, disconnect or touch the Power Cord Plug or Motor Cord Plug with wet hands.
This may cause an electric shock.
□□□
Never operate or handle the Spindle and brushless motor until you have thoroughly read the
⑤
□□□
Operation Manuals and safe operation has been confirmed.
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.
□□□□□
When installing a Spindle to a fixed base, make sure the fixed base is grounded in order to
⑥
□□□□□
avoid the risk of an electric shock.
□□□□□ ⑦ When 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.
Do not open and close the collet while the brushless motor is running.
⑧
□□□□□
⑨ Do 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.
⑩ Do not exceed the maximum recommended allowable tool speed. For your safety, use speeds
below the maximum allowable speed.
⑪ Do not apply excessive force. This may cause tool slippage, tool damage, injury to the
operator or loss of concentricity and precision.
CAUTION
Do not drop or hit this Spindle, as shock can damage to the internal components.
①
② Do not connect this Spindle to the redutcion gear. This may cause collet breakage by overload.
Be sure to clean the collet, the inside of the spindle before replacing the tool. If ground
③
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.
When cleaning a Spindle, stop the brushless motor and remove debris with a soft brush or
④
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.
Always clean the tool shank before installing the tool in the spindle.
⑤
When sizing the correct collet size to the tool shank diameter, a tolerance of +0 〜 - 0.01mm is
⑥
strongly recommended.
A tool shank within the +0 〜 - 0.1mm range is mountable, however, this may cause poor
concentricity and or insufficient tool shank gripping force.
Select suitable products or tools for all applications. Do not exceed the capabilities of the
⑦
Spindle or tools.
Do not stop the supply cooling air for motor during operation of the machine.
⑧
Removing the air pressure from the Motor / Spindle causes a loss of purging, allowing the
Motor / Spindle to ingest coolant. This will cause damage to the Motor / Spindle.
Carefully direct coolant spray to the tool. Do not spray directly on the Spindle body. If large
⑨
amount splay directly on the Spindle, it may cause excess load of the motor rotation with loss
of durability to the Spindle.
Stop working immediately when abnormal rotation or unusual vibration are observed.
⑩
Immediately, please check the content of section " 15. TROUBLESHOOTING ".
⑪ Always check if the tool, collet, connection hose and supply air hose for damaged before and
after operating.
⑫ If the collet show signs of wear or damage, replace it before a malfunction or additional
damage occurs.
After installation, repair, initial operation, or long periods of non operation, please refer to
⑬
section " 13. BREAK - IN PROCEDURE " detailed in Table. 2. When checking the Spindle, no
vibration or unusual sound should be observed during rotation.
Do not disassemble, modify or attempt to repair this Spindle . Additional damage will occur
⑭
to the internal components. Service must be performed by NSK NAKANISHI or an authorized
service center.
⑮ When 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.

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).
8 . CONNECTION OF AIR HOSE AND AIR SUPPLY
CAUTION
Securely connect the air hose to the brushless motor and air line kit to avoid accidental
disconnection and injury to the operator during use.
① Connect the provided φ6mm Air Hose with filter and 3-way valve to Air Inlet Joint shown in Fig. 3.
② Supply clean air from air compressor through air filter or air dryer to the 3-way valve at the set air pressure :
from 0.55 - 0.6MPa (79.8 - 87psi).
