11 - 1 Operation
Start supplying the
oil mist or coolant
Supplying the
coolant air
Start rotation
Supply clean and dry cooling air (Adjusting the air pressure 0.2 - 0.35 MPa (29 - 50.7psi)) into the
Brushless Motor Spindle.
* If using coolant, adjust to the air pressure 0.2 - 3.0MPa (29 - 435.1 psi).
* If using oil mist, adjust to the air pressure 0.2 - 1.0MPa (29 - 145 psi).
* Set the air pressure 0.35MPa (50.8psi) when using the Brushless Motor Spindle for continuous use.
Rotate the Brushless Motor Spindle.

Cautions for Discharging Drainage
・
Never extremely bend or break the Drain Hose
φ
6mm, causing a restriction to the drainage discharge.
If the drainage cannot be easily discharged, seaping of the drainage into the inside of the Brushless
Motor Spindle will occur, causing extreme damage to internal components, which will result in a
malfunction.
・
After stopping the supply of the coolant or oil mist, be sure to allow at least 5 minutes of cooling air
into the unit to allow adaquate time to purge the Brushless Motor Spindle. If the drainage is allowed
to remain inside the unit, damage will result causing a malfunction to the Brushless Motor Spindle.
THE METHODS OF SUPPLYING THE COOLANT OR OIL MIST
11.
・
A coolant or oil mist supply is required when operating this Brushless Motor Spindle.
* Never operate this Brushless Motor Spindle in a dry condition when using water based coolant. It
will cause internal damage to the Brushless Motor Spindle.
If this Brushless Motor Spindle is being used in a dry cutting condition, always initially supply either
oil based coolant or oil mist to the unit. After every 30 minutes of dry operation, oil based coolant or
oil mist must be re-introduced to the unit. Never operate this unit for no more than 30 minutes in a
dry state. If this Brushless Motor Spindle is run more than 30 minutes in a dry state, premature wear
to the internal parts, abnormal noise, excess heat generation and internal oil leaks to the Brushless
Motor Spindle will occur.
・
Always supply the coolant air
fi
rst into the Brushless Motor Spindle, then you may supply the
coolant or oil mist into the Brushless Motor Spindle.
If the oil mist or coolant is supplied into the Brushless Motor Spindle before the coolant air is supplied
to Brushless Motor Spindle, leakage from the coolant or oil mist will seap inside the Brushless Motor
Spindle, resulting in damage to the Brushless Motor Spindle. It is imperative that cooling air be supplied
fi
rst to assure purging of the Brushless Motor Spindle.
・
Coolant or Oil Mist must be
fi
ltered to a
fi
ltration accuracy of 5µm or less.
・
When using the Brushless Motor Spindle with the oil mist supplied for the
fi
rst time, or after a long
period of a non-use, supply the cooling air
fi
rst, then supply the oil mist for a minimum of 5 minutes
into the motor / spindle prior to use. If using the Brushless Motor Spindle is operated without
supplying suf
fi
cient oil mist, wear to the internal parts, abnormal noise, abnormal heat generation
and oil leakage into the Brushless Motor Spindle will result.
