Basic Package - Nakanishi EMSF-3060K Operation Manual

CAUTION
① Do not drop or hit this Motor Spindle, as shock can damage to the internal components.
② 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.
③ When cleaning a Motor Spindle, stop the 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.
④ Always clean the tool shank before installing the tool in the Motor Spindle.
When sizing the correct collet chuck size to the tool shank diameter, a tolerance of +0 〜 - 0.01mm
⑤
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.
⑥ Select suitable products or tools for all applications. Do not exceed the capabilities of the Motor
Spindle or tools.
⑦ Do not stop the supply cooling air for motor during operation of the machine.
Removing the air pressure from the Motor Spindle causes a loss of purging, allowing the Motor
Spindle to ingest coolant. This will cause damage to the Motor Spindle.
⑧ Carefully direct coolant spray to the tool. Do not spray directly on the Motor Spindle body.
If large amount splay directly on the Motor Spindle, it may cause excess load of the motor
rotation with loss of durability to the Motor Spindle.
⑨ Stop working immediately when abnormal rotation or unusual vibration are observed.
Immediately, please check the content of section " 13. TROUBLESHOOTING ".
⑩ Always check if the tool, collet chuck, chuck nut, connection hose and supply air hose for
damaged before and after operating.
⑪ If the collet chuck or chuck nut show signs of wear or damage, replace them before a
malfunction or additional damage occurs.
⑫ After installation, repair, initial operation, or long periods of non operation, please refer to
section " 11. BREAK-IN PROCEDURE " detailed in Table 2. When checking the spindle, no
vibration or unusual sound should be observed during rotation.
⑬ Do not disassemble, modify or attempt to repair this Motor Spindle. Additional damage will
occur to the internal components. Service must be performed by NSK NAKANISHI or an
authorized service center.
⑭ When using this Motor Spindle for mass production, please consider the purchase of an
additional Motor Spindle to be used as a back-up in case of emergency.
⑮ Securely connect the compressor supply connection hose and the air hose to the Air Line Kit
and the Motor Spindle to avoid accidental disconnection during use.
