Thank you for purchasing the Ultra-Precision, High-Speed spindle system, E3000.
The E3000 was designed for use on CNC lathes, robots, NC lathes and special purpose
machines. The motor, spindle and control unit are designed to work as an integrated system
capable of 60,000 min
-1
. This system utilizes air to cool the motor and protect the spindle,
please use an air line kit to ensure clean, dry, properly regulated air is supplied to the motor
and spindle.
The E3000 system is capable of being used with coolants and cutting lubricants.
Please read this Operation Manual carefully prior to use.
Read these cautions carefully and only use in the manner intended.
Safety instructions are intended to avoid potential hazards that could result in
personal injury or damage to the device. Safety instructions are classified as
follows in accordance with the seriousness of the risk.
CAUTIONS FOR HANDLING AND OPERATION
Class
WARNING
A hazard that could result in bodily injury or damage to the device if the safety
instructions are not 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.
Degree of Risk
WARNING
1. The E3000 is not a hand tool. It is designed to be used on a NC lathe or special
purpose machine.
2. In the event of a malfunction or breakdown, grounding provides a path of least
resistance for electric current, reducing the risk of electric shock. This system is
equipped with an electric cord with a grounding conductor and a grounding plug.
The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordnances.
3. Don't use in dangerous environments. Protect the control unit from moisture and
other contaminants. Failure to protect the control unit can result in damage to
internal components and injury to the operator.
4. Always wear safety glasses. Everyday eyeglasses only have impact resistant
lenses, they are not safety glasses. Also use a dust or face mask whenever the
motor is running.
5. Never touch the motor, spindle or cutting tools when the spindle is rotating.
6. Reduce the risk of unintentional starting. Make sure the power switch is in the
Off position before connecting the control unit or plugging the system in.
7. Do not apply excessive force. This may cause tool slippage or tool damage.
8. Do not exceed the maximum allowable tool speed. For your safety, use tools
below the maximum allowable speed.
9. Do not use bent, broken, chipped, out of round or sub-standard tools. They can
shatter or explode, and may cause injury.
CAUTION
1. Motor cooling and Spindle purge air is required to operate the system.
Air hose must be connected to the Air in joint on the front of the control unit.
Between 0.25MPa-0.3MPa air must be supplied.
2. Do not disassemble, modify or attempt to repair the unit or motor as it will
damage internal components and there are no user serviceable parts.
3. When errors occur and error lamp flashes, check and correct the cause of the
malfunction before continuing use. Failure to correct the problem will result in
damage to the unit and motor.
4. When the Warning Lamp on the control unit lights conditions exist that could
result in dangerous operation. Check operating conditions and continue use
only after correcting the problem.
5. Do not hit, drop or subject motor, spindle or control unit to shock as this will
cause damage to internal components and result in malfunctions.
6. Check the tool shank and collet prior to use to ensure they are clean and free of
burs. The introduction of foreign particles or metal chips into the collet or
spindle can cause damage and loss of precision.
7. Make sure that the collet chuck is firmly tightened prior to rotating the spindle.
If the collet chuck and chuck nut are not firmly tightened the tool may be
ejected during rotation resulting in injury.
8. The electric motor and spindle require air for cooling and protection : ensure
that this supply is clean, dry air. Introduction of dust, moisture or other
contaminants into the motor and spindle will cause damage to internal
components.
9. Do not place anything on top of the control unit or block cooling vents.
10. Do not install system next to RF noise sources as malfunctions can occur. If
smoke, noise or strange odors emanate from the unit or motors immediately
turn off the power switch, disconnect and take to a NAKANISHI dealer for
evaluation.
11. Use only tools with shank diameter tolerance similar to the chuck I.D. tolerance.
12. Check if tools, chucks or chuck nuts are damaged before working.
13. When using NE211 continuously, refer to Continuous Area on Torque
Characteristics or check LOAD meter maximum (3 Green Lamps).
14. Attach the provided connector cover when not using Input/Output Connector
A/B or Selector Communication Connector.
15. Stop working immediately when abnormal rotations or unusual vibration are
observed.
16. Do not over tighten the chuck. This may cause spindle damage.
17. Select suitable products or tools for the applications. Do not exceed the
capabilities of the spindles or cutting tools.
