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