Changing The Tool - Nakanishi NR33-6000ATC-ESD Operation Manual

・ Please purchase the recommended commercially available air inlet fitting for the air inlet joint.
recommended air inlet
(With outside diameter of φ9.9mm or less)
・ When installing the collet clamp / unclamp fittings, thoroughly read the instructions before connecting.(Fig. 4)

9 . CHANGING THE TOOL

WARNING
Do not open and close the collet while the brushless motor is running.
CAUTION
When the air is supplied to the inlet joint of the Spindle, the tool will be pushed out by exhausting
・
the coolant air of brushless motor from the edge of Spindle. Be careful not to be damaged to the
tool or be injured.
Use the air on-off valve through which the air can be exhausted. Do not use 2 way valve, because
・
the 2 way valve is not echausted and the collet is not closed.
Do not open and close the collet before the tool is not installed. Because this will cause damage
・
to the collet or loss of precision.
RECOMMENDATION
Please set the cutting tools to minimize the overhang amount. 13mm is the maximum amount of
overhang to maintain high accuracy and safety.
① Stop the brushless motor and check that the motor is not rotating before replacement.
② Supply air pressure: from 0.55 - 0.6MPa (79.8 - 87.0psi) to Air Inlet Joint through 3-way valve. Then, the collet
will be opened.
At the same time, the tool is pushed out by the air exhaust for the coolant of brushless motor. So, need the tool
holder not to be damaged to the tool.
③ Replace the tool.
④ Exhaust the air through 3-way valve. The collet will be closed and the tool can be fixed.
