Lever Type Spindle

OPERATION MANUAL

003

OM-K0539E

Thank you for purchasing the Lever Type Spindle " NRR - 3060 ". This Spindle has a simple lever operated 
collet. No wrenches are required for tool changing. This Spindle is designed for cutting PC boards. 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.

 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 classi

¿

ed 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.

This Spindle is not a hand tool. It is designed to be used on CNC machines or special purpose 
machines.

Do not touch the cutting tool while it is running. It is very dangerous.

Wear safety glasses, dust mask, and use a protective cover around the Spindle whenever the 
Spindle is rotating.

Never connect, disconnect or touch the Power Cord Plug or Motor Cord Plug with wet hands. This 
may cause an electric shock.

Never operate or handle the Spindle and brushless motor until you have thoroughly read the 
Operation Manuals and safe operation has been con

¿

rmed. 

1) To prevent injuries / damages, check the Spindle, brushless motor and cutting tool for proper 

installation, before operating the Spindle and brushless motor. 

2) Before disconnecting the Spindle and brushless motor, always turn the control power off and 

turn the compressed air supply to the CONTROLLER off. Then it is safe to remove the Spindle 
and brushless motor.

When installing a Spindle to a 

¿

xed base, make sure the 

¿

xed base is grounded in order to avoid 

the risk of an electric shock.

Stop the brushless motor prior to operating the lever. If lever operation is performed during 
spindle rotation, contact with internal components will damage the spindle.

Make sure that lever position is LOCK before rotating with mounting cutting tool.

When installing a tool, tighten the collet correctly and check again the collet before use. Do not 
over-tighten the collet. This may cause damage to the spindle.

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.

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 or 
loss of concentricity and precision.

 

 WARNING

Do not drop or hit this Spindle, as shock can damage to the internal components.

Do not connect this Spindle to the reduction gear. This may cause collet breakage by overload.

Be sure to clean the collet, 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.

When cleaning a Spindle, stop the brushless motor 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. 

Always clean the tool shank before installing the tool in the spindle.

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 insuf

¿

cient tool shank gripping force. 

Select suitable products or tools for all applications. Do not exceed the capabilities of the Spindle 
or tools.

Do not stop the supplied cooling air to the brushless motor during operation of the machine. 
Removing the air pressure from the brushless motor causes a loss of purging, allowing the 
Spindle to ingest coolant and debris. This will cause damage to the Spindle. 

Carefully direct coolant spray directly on the tool. Do not spray directly on the Spindle body. If 
large amount spray directly on the Spindle, it may cause excess load of the Spindle rotation with 
loss of durability to the Spindle. 

Stop working immediately when abnormal rotation or unusual vibration are observed. Immediately, 
please check the content of section " 14. TROUBLESHOOTING ". 

Always check if the tool, collet are damaged before and after operating.

If the collet show signs of wear or damage, replace it before a malfunction or additional damage 
occurs.

After installation, repair, initial operation, or long periods of non operation, please refer to section 
" 13. BREAK-IN PROCEDURE " detailed in Table. 2. When checking the Spindle, no vibration or 
unusual sound should be observed during rotation.

CONNECTION OF THE SPINDLE TO THE MOTOR

7.

Make sure your hands and all interlocking parts of the brushless moto and Spindle are clean before 
connecting the Spindle to the brushless motor. This is critical in preventing contaminants from 
entering the Spindle or brushless motor.

 

 CAUTION

Align the thread on the front end of the 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 approximately 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).
