①
Remove the tool according to the section " 7.
CHANGING THE TOOL " procedure above
and remove chuck nut assembly (Fig. 4).
②
The collet chuck and chuck nut are secured
by a groove in the collet chuck and a ange
in the chuck nut. To remove the collet chuck
hold the chuck nut in one hand and push
diagonally down on the collet chuck. The
collet chuck should be released (Fig. 5).
③
To install the collet chuck, hold the collet
chuck at a slight angle, and insert it into the
chuck nut (Fig. 6).
Press the collet chuck in the chuck nut by
positioning the collet chuck in the chuck nut
and pressing down on at surface (Fig. 5).
Be sure to fully engage the latch inside
the chuck nut into the groove on the collet
chuck's outer circumference area (Fig. 7).
①
Set the provided 12mm wrench on the
spindle.
②
Place the provided 14mm wrench on the
chuck nut and turn it counterclockwise to
loosen the collet chuck and remove the
tool. (The rst 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 chuck will open.)
③
Clean the collet chuck and chuck nut,
then insert the new tool and tighten the
collet chuck by turning clockwise. Do not
overtighten.

OPERATION MANUAL
003
OM-K0525E
Thank you for purchasing Motor Spindle " EMS - 3060K
・
EMS - 3060K - 1M ". This Motor Spindle is designed for
grinding, small diameter drilling and milling, etc. The E3000 CONTROLLER and Air Line Kit are required 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.
■
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 classied 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.
CAUTIONS FOR HANDLING AND OPERATION
1.
①
This Motor 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 Motor Spindle whenever
the Motor 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 Motor Spindle until you have thoroughly read the Operation Manuals
and safe operation has been conrmed.
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.
⑥
When installing a Motor Spindle to a xed base, make sure the xed 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 and
chuck nut before use. Do not over-tighten the collet chuck. This may cause damage to the spindle.
⑧
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.
⑨
Do not exceed the maximum recommended allowable tool speed. For your safety, use speeds
below the maximum allowable speed.
⑩
Do not apply excessive force. This may cause tool slippage, tool damage, injury to the operator or
loss of concentricity and precision.
WARNING
①
Do not drop or hit this Motor Spindle, as shock can damage to the internal components.
②
Be sure to clean the collet chuck and chuck nut, 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.
③
When 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.
④
Always clean the tool shank before installing the tool in the Motor Spindle.
⑤
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 insufcient tool shank gripping force.
⑥
Select suitable products or tools for all applications. Do not exceed the capabilities of the Motor
Spindle or tools.
⑦
Do 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.
⑧
Carefully direct coolant spray to the tool. Do not spray directly on the Motor Spindle body. If large
amount spray directly on the Motor Spindle, it may cause excess load of the motor rotation with
loss of durability to the Motor Spindle.
⑨
Stop working immediately when abnormal rotation or unusual vibration are observed. Immediately,
please check the content of section " 13. TROUBLESHOOTING ".
⑩
Always check if the tool, collet chuck, chuck nut, connection hose and supply air hose for
damaged before and after operating.
⑪
If the collet chuck or chuck nut show signs of wear or damage, replace them before a malfunction
or additional damage occurs.
⑫
After 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 Spindl, 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.
⑭
When using this Motor Spindle for mass production, please consider the purchase of an additional
Motor Spindle to be used as a back-up in case of emergency.
⑮
Securely connect the compressor supply connection hose and the air hose to the Air Line Kit and
the Motor Spindle to avoid accidental disconnection during use.

Do not tighten the collet chuck without inserting a tool or dummy bur, as this will damage the collet
chuck, spindle or chuck nut, causing difculty removing the collet chuck.
CAUTION
Please set the cutting tools to minimize the overhang amount. 13mm is the maximum amount of
overhang to maintain high accuracy and safety.
RECOMMENDATION
Fig. 3
When installing the collet chuck into the chuck nut, be sure to fully engage the latch inside the chuck
nut to the groove on the collet chucks outer diameter area. In addition, remember that if the collet
chuck is attached without being engaged with the latch of the chuck nut, the collet chuck cannot be
removed and this may cause damage to the collet chuck or the spindle.
