Nakanishi RA-200 Operation Manual

90
° Angle Spindle
RA - 200
OPERATION MANUAL
Thank you for purchasing 90° Angle Spindle " RA - 200 ". This Spindle is designed for drilling on side faces,
or working on corners dif¿cult to work or un¿t for working with straight type Spindles. The E2530 Control Unit,
Brushless Motor or Air Motor and Air Line Kit with Lubricator combination are required to drive this Spindle. Read
this and all the associated component Operation Manuals carefully before use. Always keep this Operation Manual
in a place where a user can referred to for reference at any time.
1 . CAUTIONS FOR HANDLING AND OPERATION
■ Read these warnings and cautions carefully and only use in the manner intended.
■ These warnings and cautions are intended to avoid potential hazards that could result in personal injury to the
operator or damage to the device. These are classi¿ed as follows in accordance with the seriousness of the risk.
Class
A safety hazard could result in bodily injury or damage to the device if the
WARNING
safety instructions are not properly followed.
A hazard that could result in light or moderate bodily injury or damage
CAUTION
to the device if the safety instructions are not followed.
WARNING
① This Spindle is not a hand tool. It is designed to be used on CNC machines or special purpose
machines.
② Do not touch the cutting tool while it is running. It is very dangerous.
③ Wear safety glasses, dust mask and use a protective cover around the Spindle whenever the
Spindle is rotating.
④ Never connect, disconnect or touch the Power Cord Plug or Motor Cord Plug with wet hands.
This may cause an electric shock.
⑤ Never operate or handle the Spindle and brushless motor until you have thoroughly read the
Operation Manuals and safe operation has been con¿rmed.
1) To prevent injuries / damages, check the Spindle, brushless motor and cutting tool for
proper installation, before operating the Spindle and brushless motor.
2) Before disconnecting the Spindle and brushless motor, always turn the control power off
and turn the compressed air supply to the CONTROLLER off. Then it is safe to remove the
Spindle and brushless motor.
⑥ When installing a Spindle to a ¿xed base, make sure the ¿xed base is grounded in order to
avoid the risk of an electric shock.
⑦ When installing a tool, tighten the collet correctly and check again the collet before use. Do not
over-tighten the collet. This may cause damage to the Spindle.
⑧ Do not use bent, broken, chipped, out of round or sub-standard tools, as this may cause them
to shatter or explode. Tools with fractures or a bent shank will cause injury to the operator.
When using a new tool, rotate it in a low speed and increase speed gradually for safety.
⑨ Do not exceed the maximum recommended allowable tool speed. For your safety, use speeds
below the maximum allowable speed.
⑩ Do not apply excessive force. This may cause tool slippage, tool damage, injury to the operator
or loss of concentricity and precision.
CAUTION
① Do not exceed the maximum allowable motor speed of 20,000min
② The speed reducer is always used to connect between the air motor AM - 300 ‡ AM - 310 and
RA - 200.
③ Do not drop or hit this Spindle, as shock can damage to the internal components.
④ Be sure to clean the collet, 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.
⑤ When cleaning a Spindle, stop the motor and remove debris with a soft brush or a cloth. Do
not blow air into the Spindle with compressed air as foreign particles or cutting debris may
get into the ball bearing.
⑥ Always clean the tool shank before installing the tool in the Spindle.
When sizing the correct collet size to the tool shank diameter, a tolerance of +0 〜 - 0.01mm is
⑦
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.
⑧ Select suitable products or tools for all applications. Do not exceed the capabilities of the
Spindle or tools.
⑨ Do not stop the supply cooling air for motor during operation of the machine.
Removing the air pressure from the Spindle causes a loss of purging, allowing the Spindle to
ingest coolant. This will cause damage to the Spindle.
⑩ Carefully direct coolant spray to the tool. Do not spray directly on the Spindle body. If large
amount spray directly on the Spindle, it may cause excess load of the motor rotation with loss
of durability to the Spindle.
⑪ Stop working immediately when abnormal rotation or unusual vibration are observed.
Immediately, please check the content of section " 13. TROUBLESHOOTING ".
⑫ Always check if the tool, collet are damaged before and after operating.
⑬ If the collet show signs of wear or damage, replace it before a malfunction or additional
damage occurs.
⑭ 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.
⑮ Do not disassemble, modify or attempt to repair this Spindle. Additional damage will occur
to the internal components. Service must be performed by NSK NAKANISHI or an authorized
service center.
⑯ When using this Spindle for mass production, please consider the purchase of an additional
Spindle to be used as a back-up in case of emergency.

7 . CONNECTION OF THE SPINDLE TO THE MOTOR
CAUTION
Make sure your hands and all interlocking parts of the Spindle and motor are clean before
connecting the motor to the Spindle. This is critical in preventing contaminants from entering the
motor or Spindle.
Align the thread on the front end of the brushless motor /
reducer and the rear of the Spindle, and turn the Spindle
clockwise. If the drive shaft of the brushless motor / reducer
does not engage properly to the drive dog on the spindle,it
may only turn approximately two threads before stopping. DO
NOT FORCE THEM TOGETHER. Loosen the Spindle from the
brushless motor / reducer, rotate the Spindle shaft by hand then
re-try. The drive shaft and the drive dog must be fully engaged.
When fully engaged, secure the brushless motor / reducer and
Spindle using the provided 20mm wrench (Fig. 2) .
