⑳When disposal of a CONTROLLER is necessary, follow the instructions from your local
government agency and dispose as an industrial waste.
㉑When using the Air Bearing Spindle, please supply the recommended regulated air pressure to
the Air Bearing. When rotating the spindle with less the regulated air pressure, this may make
you damage to the spindle or the CONTROLLER.
㉒Be sure to clean the collet and collet 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, damage to the collet
or spindle can occur due to the loss of precision.
㉓ Always clean the tool shank and the machine spindle taper before installing the tool in the machine.
㉔When 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 insuf¿cient tool shank gripping force.
㉕Select suitable products or tools for all applications. Do not exceed the capabilities of the
spindle or tools.
㉖Do not stop the supplied cooling air to the motor, spindle, motor spindle, during operation of
the machine.
Removing the air pressure from the motor, spindle, motor spindle, causes a loss of purging,
allowing the motor, spindle, motor spindle, to ingest coolant and debris. This will cause
damage to the motor, spindle, motor spindle.
㉗Carefully direct coolant spray to the tool. Do not spray directly on the spindle body. If large
amount splay directly on the spindle, it may cause excess load of the motor rotation with loss
of durability to the motor / spindle.
㉘Stop working immediately when abnormal rotation or unusual vibration are observed.
Afterwards, please check the content of Section " 20. TROUBLESHOOTING ".
㉙Always check if the tool, collet or collet nut are damaged before and after operating.
