OPERATION MANUAL
Thank you for purchasing motor spindle BMS-5010 ・ BMS-5010RA. This motor spindle is designed for high precision
machining including grinding, drilling and milling. The <E4000 CONTROLLER> and the <Air Line Kit> are required to
drive this motor spindle. Read this Operation Manual carefully before use. Also read <E4000 CONTROLLER> and
the <Air Line Kit> Operation Manual.
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 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.
WARNING
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 hearing protection, 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 and Motor Cord Connector with wet
hands. This may cause an electric shock.
⑤
Never operate or handle the motor spindle until you have thoroughly read the owner's manual
and safe operation has been confirmed.
1
）
To prevent injuries/damages, check this motor spindle and cutting tool for proper installation,
then operate this motor spindle.
2
）
Before disconnecting this motor spindle, always turn the control power off and turn the
compressed air supply to the control unit off. It is then safe to remove this motor spindle.
⑥
When 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 motor spindle.
⑦
Do not use bent, broken, chipped, out of round or sub-standard tools as they can shatter or
explode. It shatters, it cracked, and the tool that bends and breaks disperses and it causing
injures. When using a new tool, rotate it in a low speed and increase speed gradually for safety.
⑧
Do not exceed the maximum recommended allowable tool speed. For your safety, use speeds
below the maximum allowable speed.
⑨
Do not apply excessive force. This may cause tool slippage, tool damage, injury to the operator,
loss of concentricity and precision.
CAUTION
①
Do not drop or hit this motor spindle, as shock can damage to the internal components.
②
Be sure to clean the collet and collet 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, damage to the collet
or spindle can occur due to the loss of precision.
③
When cleaning a spindle, stop the motor and remove dirt with a brush or a cloth. Do not blow air
to a dust proof area (refer to Section 6 - 2 "Outside View") with compressed air, foreign particles
or cutting chips might get into the ball bearing.
④
Always clean the tool shank before installing the tool in the motor spindle.
⑤
Please select the suitable tool diameter from Table 2 for each collet size. If you use a tool that is
out of range, you may experience problems such as core runout, insufficient holding power, and
collet deformation.
⑥
Select suitable products or tools for all applications. Do not exceed the capabilities of the motor
spindle or tools.
⑦
Carefully direct coolant spray to the tool. Do not spray directly on the motor spindle body.
⑧
Stop working immediately when abnormal rotation or unusual vibration are observed. Afterwards,
please check the content of Section "15. TROUBLESHOOTING".
⑨
Always check if the tool, collet or collet nut are damaged before and after operating.
⑩
If the collet or collet nut show signs of wear or damage, replace them before a malfunction or
additional damage occurs.
⑪
After installation, repair, initial operation, or long periods of non operation, please refer to Section
"12. BREAK-IN PROCEDURE" detailed in Table. 3. When checking the motor spindle, no vibration
or unusual sound should be observed during rotation.
⑫
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.
⑬
When using this motor spindle for mass production, please purchase the another motor spindle
as a spare in case of an emergency.

Please set the air pressure to 0.35 MPa for continuous use, although the motor spindle can be operated at the air
pressure within 0.2 MPa~0.35 MPa.
7. INSTALLING THE COLLET
CAUTION
• Be sure to clean the collet, the collet nut and the inside of the spindle before installing the collet
or the tool. If ground particles or metal chips stick to the inside of the spindle or the collet,
damage to the collet or spindle can occur due to the loss of precision.
• When installing the collet in the collet nut, make sure that the latches of the collet nut are properly
seated in the groove of the collet. If the latches are not properly seated when you tighten the
collet nut, the collet may become stuck inside the spindle.
• Never tighten the collet nut without inserting a tool in the collet. Excessively tightening the collet
may damage the latches that hold the collet in the collet nut, making it difficult to remove the
collet from the spindle.
• Keep the overhang length to a minimum when installing the tool. If the overhang length is too
long, the tool may bend and cause injury.
① Hold the collet nut in one hand, and install
the collet. (Fig. 4)
If the collet is difficult to install, tilt the collet
to one side when inserting it, so that the
latches can more easily be seated in the
groove. (Fig. 5)
At this time, make sure that the latches of
the collet nut are properly seated in the
groove of the collet. (Fig. 6)
②
Insert the tool, place the provided 22 mm
wrench on the wrench flats of the spindle
shaft and place the provided 27mm wrench
on the collet nut and turn clockwise to
secure the tool.
8. CHANGING THE TOOL
① Place the provided 22 mm wrench on the wrench flats of the spindle shaft. (Fig. 7)
② Place the provided 27 mm wrench on the collet nut and turn it counterclockwise to loosen the collet and remove
the tool. (Fig. 7)
(The first turn of the collet holder is stiff. Keep turning through the stiffness and the collet will open. The turning
may not become stiff.)
③ Insert the new tool and turn the collet nut clockwise to secure the tool. (Fig. 7)
9. REPLACING THE COLLET
① Loosen the collet nut with the tool installed as described in
section "8. CHANGING THE TOOL". Keep turning the collet nut
until it comes out of the spindle shaft together with the tool, and
then remove the tool from the collet. (Fig. 8)
② Hold the collet nut in one hand, and tilt the collet to one side to
release it. If the collet is not released, try tilting it to the other
side. (Fig. 5)
③ Install the collet as described in section "7. INSTALLING THE
COLLET".
