CAUTION
③When cleaning a Brushless Motor Spindle, stop the 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.
④Always clean the tool shank before installing the tool in the spindle.
⑤When 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 insufficient tool shank gripping force.
⑥Check to make sure the Brushless Motor Spindle is properly and securely mounted
in the machine's spindle prior to use. If the Brushless Motor Spindle is not properly
aligned or there is excessive play, do not use the Brushless Motor Spindle until this
situation is corrected.
⑦Select suitable products or tools for all applications. Do not exceed the capabilities of
the Brushless Motor Spindle or tools.
⑧Do not stop the supplied cooling air to the Brushless Motor Spindle during operation
of the machine.
Removing the air pressure from the Brushless Motor Spindle causes a loss of purging,
allowing the Brushless Motor Spindle to ingest coolant and debris. This will cause
damage to the Brushless Motor Spindle.
⑨Carefully direct coolant spray directly on the tool. Do not spray directly on the
Brushless Motor Spindle collet nut. Large amounts of coolant sprayed directly on
the Brushless Motor Spindle may cause excess load of the Brushless Motor Spindle,
causing a loss of durability and longevity of the Brushless Motor Spindle.
⑩Stop working immediately when abnormal rotation or unusual vibration are observed.
Immediately, please check the content of section " 14. TROUBLESHOOTING ".
⑪Always check if the tool, collet, collet nut, connection hose and supply air hose for
damage before and after operating.
⑫If the collet or collet nut show signs of wear or damage, replace them before a
malfunction or additional damage occurs.
⑬After 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
Brushless Motor Spindle, no vibration or unusual sound should be observed during
rotation.
⑭Do not disassemble, modify or attempt to repair this Brushless Motor Spindle.
Additional damage will occur to the internal components. Service must be performed
by NSK NAKANISHI or an authorized service center.
⑮When using this Brushless Motor Spindle for mass production, please consider the
purchase of an additional Brushless Motor Spindle to be used as a back-up in case of
emergency.
⑯Securely connect the compressor supply connection hose to the Air Line Kit, and
connect the air hose to the Air Line Kit, CONTROLLER and the Brushless Motor
Spindle to avoid accidental disconnection during use.
