Thank you for purchasing the Ultra-Precision, High-Speed Brushless Motor Spindle " HES510 ". The HES510
Brushless Motor Spindle is designed for use on machining centers without rotating the machine's main spindle, for
small diameter drilling and milling. The E3000 CONTROLLER and Air Line Kit are rquired to drive this Brushless 
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.

DANGER

Do not rotate the machining center's main spindle with the HES Brushless Motor Spindle installed. 
Rotating the machining center's main spindle with the HES Brushless Motor Spindle installed 
can cause the motor cord to become tangled and pull the control unit off it is mounting. This may 
cause lead to a big accident.

. 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 classi

¿

ed as follows in accordance with the seriousness of the risk.

Class

Degree of Risk

 DANGER

Existence of a hazard that could result in personal death or serious 
injury, if the safety precautions are not fo.

 WARNING

A safety hazard could result in bodily injury or damage to the device if 
the safety instructions are not properly followed.

 C A U T I O N

A hazard that could result in light or moderate bodily injury or damage 
to the device if the safety instructions are not followed.

NAKANISHI product's are intended for use by trained, knowledgeable, highly experienced 
professionals only.

This Brushless Motor Spindle is not a hand tool. It is designed to be used install this Brushless 
Motor Spindle to the machining center's machines or milling machine 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 HES Brushless Motor 
Spindle whenever the HES Brushless Motor 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 HES Brushless Motor Spindle until you have thoroughly read the 
Operation Manuals and safe operation has been con

¿

rmed.

1

 To prevent injuries / damages, check the HES Brushless Motor Spindle and cutting tool for 
proper installation, before operating the HES Brushless Motor Spindle.

2

 Before disconnecting the HES Brushless 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 
HES Brushless Motor Spindle.

When installing a HES Brushless Motor Spindle to a 

¿

xed base, make sure the 

¿

xed base is 

grounded in order to avoid the risk of an electric shock.

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 HES 
Brushless Motor 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 HES Brushless Motor Spindle, as shock can damage to the internal 
components.

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.

When cleaning a HES Brushless Motor Spindle, stop the HES510 Brushless 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.

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

Be sure to drain moisture and condensation from the Air Line Kit (air 

¿

lter bowl) regularly to 

avoid moisture being carried to the HES Brushless Motor Spindle. This may cause damage to 
the HES Brushless Motor Spindle.

Check to make sure the HES Brushless Motor Spindle is properly and securely mounted in the 
machine's quill prior to use. If the HES Brushless Motor Spindle is not properly aligned or there 
is excessive play, do not use the HES Brushless Motor Spindle until this situation is corrected.

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 insuf

¿

cient tool shank gripping force.

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

Do not stop the supply cooling air for motor during operation of the machine.
Removing the air pressure from the HES Brushless Motor Spindle causes a loss of purging, 
allowing the HES Brushless Motor Spindle to ingest coolant. This will cause damage to the 
HES Brushless Motor Spindle.

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

Stop working immediately when abnormal rotation or unusual vibration are observed.
Immediately, please check the content of section " 13. TROUBLESHOOTING ".

Always check if the tool, collet chuck, chuck nut, connection hose and air hose for damaged 
before and after operating.

Always check if the tool, collet chuck, chuck nut, connection hose and air hose for damaged 
before and after operating.

After installation, repair, initial operation, or long periods of non operation, please refer to 
section " 12. BREAK-IN PROCEDURE " detailed in Table 2. When checking the spindle, no 
vibration or unusual sound should be observed during rotation.

Do not disassemble, modify or attempt to repair this HES Brushless Motor Spindle. Additional 
damage will occur to the internal components. Service must be performed by NSK NAKANISHI 
or an authorized service center.

When using this HES Brushless Motor Spindle for mass production, please consider the purchase 
of an additional HES Brushless Motor Spindle to be used as a back-up in case of emergency.

Securely connect the compressor supply connection hose and the air hose to the Air Line Kit 
and the HES Brushless Motor Spindle to avoid accidental disconnection during use.
