Automatic Tool Replacement Spindle
NR50 - 5100 ATC RS
OPERATION MANUAL
Thank you for purchasing Automatic Tool Replacement Spindle " NR50 - 5100 ATC RS ". 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 This 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.
③ Wear safety glasses, dust mask, and use a protective cover around the Spindle whenever the
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.
⑤ Never operate or handle the brushless motor and Spindle until you have thoroughly read the
Operation Manuals and safe operation has been confirmed.
1 ) To prevent injuries / damages, check the brushless motor, Spindle and cutting tool for
proper installation, before operating the brushless motor and Spindle.
2 ) Before disconnecting the brushless motor and Spindle, always turn the control power off
and turn the compressed air supply to the CONTROLLER off. Then it is safe to remove the
brushless motor and Spindle.
⑥ When installing a Spindle to a fixed base, make sure the fixed base is grounded in order to
avoid the risk of an electric shock.
⑦ When installing a tool, tighten the collet chuck correctly and check again the collet chuck
before use. Do not over-tighten the collet chuck. This may cause damage to the Spindle.
⑧ Do not open and close the collet chuck while the brushless motor is runing.
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.
Do not apply excessive force. This may cause tool slippage, tool damage, injury to the operator
⑪
or loss of concentricity and precision.
CAUTION
① Do not drop or hit this Spindle, as shock can damage to the internal components.
② Do not connect this Spindle to the reduction gear. This may cause collet chuck breakage by
overload.
③ Be sure to clean the collet chuck, the inside of the Spindle before replacing the tool. If ground
particles or metal chips stick to the inside of Spindle or the collet chuck, damage to the collet
chuck or Spindle can occur due to the loss of precision.
④ When 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.
⑤ Always clean the tool shank before installing the tool in the Spindle.
⑥ When sizing the correct collet chuck 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 insufficient tool shank gripping force.
⑦ Select suitable products or tools for all applications. Do not exceed the capabilities of the
Spindle or tools.
⑧ Do not stop the brushless motor and Spindle while coolant spray is being applied to the
cutting tool. Removing the air pressure from the brushless motor and Spindle causes a loss of
purging, allowing the brushless motor and Spindle to ingest coolant. This will cause damage to
the brushless motor and Spindle.
⑨ Carefully direct coolant spray to the tool. Do not spray directly on the Spindle body. If large
amount splay directly on the Spindle, it may cause excess load of the motor rotation with loss
of durability to the Spindle.
⑩ Stop working immediately when abnormal rotation or unusual vibration are observed.
Immediately, please check the content of section " 14. TROUBLESHOOTING".
⑪ Always check if the tool, collet chuck, connection hose and supply air / oil hose for damaged
before and after operating.
⑫ If the collet chuck show signs of wear or damage, replace it before a malfunction or additional
damage occurs.
⑬ After 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.
⑭ Do 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.
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 brushless motor to the Spindle. This is critical in preventing contaminants
from entering the brushless motor or Spindle.
Align the thread on the front end of the Transmission Clutch
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 6mm 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.

〈 When using the rear air inlet joint 〉
CAUTION
・ The rear air inlet port is closed with an M5 screw before shipment. When changing the air inlet
port location, remove the M5 screw to install an air inlet joint.
・ Use any one of the two air inlet port. Be sure to close the unused air inlet port with the removed
M5 screw.
・ After installing the fitting, supply air and confirm that there is no air leakage, then proceed with
the installation.
・ Please purchase the recommended commercially available air inlet fitting for the air inlet joint.
recommended air inlet SMC is KQ2S04-M5N. 6mm to 4mm tubing reducer SMC is KQ2H04-06A.
・ When installing the collet chuck clamp / unclamp fittings, thoroughly read the instructions before connecting.
