Thank you for purchasing the Motor Spindle " EMSF-3060K-RBT ". This Motor Spindle is designed for grinding,
small diameter drilling and milling, etc. The E3000 CONTROLLER and Air Line Kit are rquired to drive this Motor
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
WARNING A safety hazard could result in bodily injury or damage to the device if
the safety instructions are not properly followed.
CAUTION A hazard that could result in light or moderate bodily injury or damage
to the device if the safety instructions are not followed.
①This Motor 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 Motor Spindle until you have thoroughly read the Operation Manuals
and safe operation has been confirmed.
1) To prevent injuries / damages, check the Motor Spindle and cutting tool for proper installation,
before operating the Motor Spindle.
2) Before disconnecting the Motor Spindle, always turn the control power off and turn the
compressed air supply to the CONTROLLER off. Then it is safe to remove the Motor Spindle.
⑥Whenever installing a Motor Spindle to a fixed metal base, ensure that the fixed metal base is
grounded in order to avoid risk of an electric shock.
⑦When installing a tool, tighten the collet correctly and check again the collet and collet nut before
use. Do not over-tighten the collet. This may cause damage to the spindle.
⑧Do 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.
⑨Do not exceed the recommended maximum allowable speed of the tool. For your safety, use speeds
below the maximum allowable speed.
⑩Do not apply excessive force. This may cause injury to the operator by slippage or damage of

EMSF - 3060K - RBT : 0.3m
CAUTION
①Do not drop or hit this Motor Spindle, as shock can damage to the internal components.
②Be sure to clean the collet and collet nut, the inside of the spindle before replacing the tool
(cutting 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.
③When cleaning a Motor Spindle, stop the Motor Spindle and remove debris with a soft brush or
a cloth. Do not blow air into the dust proof cover area (refer to section " 6 - 2 Outside View ")
with compressed air as foreign particles or cutting debris may get into the ball bearing.
④Always clean the tool shank before installing the tool in the Motor Spindle.
⑤
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 insufficient tool shank gripping force.
⑥
Select suitable products or tools for all applications. Do not exceed the capabilities of the Motor
Spindle or tools.
⑦Do not stop the supply cooling air for motor during operation of the machine.
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.
⑧Carefully direct coolant spray directly on the tool. Do not spray directly on the Motor Spindle
and collet nut. Large amounts of coolant sprayed directly on the Motor Spindle may cause
excess load of the Motor Spindle causing a loss of durability and longevity of the Motor
Spindle.
⑨Stop working immediately when abnormal rotation or unusual vibration are observed.
Immediately, please check the content of section " 13. TROUBLESHOOTING ".
⑩Always check if the tool, collet, collet nut, connection hose and supply air hose for damaged
before and after operating.
⑪If the collet or collet nut show signs of wear or damage, replace them before a malfunction or
additional damage occurs.
⑫After installation, repair, initial operation, or long periods of non operation, please refer to
section " 11. BREAK-IN PROCEDURE " detailed in Table 2. When checking the Motor Spindle,
no vibration or unusual sound should be observed during rotation.
⑬
Do not disassemble, modify or attempt to repair this Motor Spindle. Additional damage will
occur to the internal components. Service must be performed by NSK NAKANISHI or an
authorized service center.
⑭When using this Motor Spindle for mass production, please consider the purchase of an

The Motor Spindle housing temperature during the
break-in process should not exceed 20 degrees C
(36 degrees F) above ambient temperature. Should
the Motor Spindle exceed this limit, rest the motor
spindle for at least 20 minutes and re-start the break
in procedure from the beginning. If the housing
temperature rises again and exceeds 20 degrees C
(36 degrees F) above ambient temperature, check
the Motor Spindle for proper installation.
The Motor Spindle
housing temperature
during the break-in
process should not
exceed 25 degrees
C (45 degrees F)
above ambient
temperature.
Table 2.
11. BREAK-IN PROCEDURE
During transportation, storage or installation, the grease inside the bearings will settle. If the Motor Spindle is
suddenly run at high-speed, the grease will be ejected from the bearings, causing excessive heat that will cause
bearing damage.
After installation, repair, initial operation, or long periods of non operation, please follow the break-in procedure
detailed in Table 2.
①The proper surface speed for general grindstones is 10-30m / s.
②Do not exceed 13mm of overhang for mounted grindstones as shown in Fig. 15. If the overhang must exceed
13mm, reduce the brushless motor speed in accordance with Table 3.
③Dress the grindstone prior to use.
④Do not use cutting tools with bent or broken shanks, cracks or excessive run-out.
⑤For grinding, the maximum depth of cut should not exceed 0.01mm radially or axially. Reciprocate the tool
several times after each pass to eliminate tool pressure.
⑥
Always operate cutting tools within the allowable recommended speed of the cutting tools. Use of a cutting tool
outside of the allowable speed of the cutting tools could cause damage to the Spindle and injury to the operator.
