CAUTIONS FOR HANDLING AND OPERATION
1.
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 Motor Spindle whenever
the Motor 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 conrmed.
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.
⑥When 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.
⑦When 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.
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 maximum recommended allowable tool speed. For your safety, use speeds
below the maximum allowable speed.
⑩Do not apply excessive force. This may cause tool slippage, tool damage, injury to the operator or
loss of concentricity and precision.
WARNING
①Do not drop or hit this Motor Spindle, as shock can damage to the internal components.
②Be 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.
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.
⑤When 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 insufcient tool shank gripping force.
⑥Select 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 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.
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 chuck, chuck nut, connection hose and supply air hose for
damaged before and after operating.
⑪If the collet chuck or chuck 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

CAUTION
・How to conrm the correct tightening or clamping of the Motor Spindles in the holder
Measure the current value of the CONTROLLER's power cord by the clamp meter.
Fasten the holder so that the increase in the no-load current value (during rotation at the maximum
rotation speed) with the Motor Spindle fastened is 20mA (for type 120V) / 10mA (for type 200V / 230V)
or less, compared to the no-load current value (during rotation at the maximum rotation speed)
without fastening the Motor Spindle. Do not over-tighten the Fastening Bolt. It may damage Motor
Spindle's precision and shorten the life of the bearings.
・The nal responsibility for ensuring holderʼs safety for use in a given application is left to the
designer of the equipment in which NAKANISHI's Motor Spindle is installed.
NAKANISHI offers Motor Spindles with a wide variety of capabilities and specications.
Please carefully check the Motor Spindle's specications against the requirements of your

CAUTION
BREAK-IN PROCEDURE
11.
During transportation, storage or installation, the grease inside the bearings will settle. If the 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. 20. If the overhang must exceed
13mm, reduce the 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.
⑥Always 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.
⑦Keep the cutting tool shank and collet chuck clean. If contaminants are left in the collet chuck or chuck nut,
excessive run-out will cause damage to the cutting tool and or spindle.
⑧Do not strike or disassemble the spindle.
⑨Please set the cutting tools to minimize the overhang amount. 13mm is the maximum amount of overhang to
maintain high accuracy and safety.
