Nakanishi IC-300 User manual

OPERATION MANUAL 002
OM-K0032E
Thank you for purchasing the 90°/ 50°Angle Attachment " IC - 300・EIC - 300・KC - 300・EKC - 300 ". This
Attachment is designed for polishing corners and internal surfaces and Àat surfaces with rubber pad. The Emax
EVOlution control unit and motor, Espert 500 control unit and motor, and ROTUS air motor and Air Line Kit are
required to drive this Attachment. 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.
■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 Degree of Risk
WARNING A safety hazard could result in bodily injury or damage to the
device if the safety instructions are not properly followed.
CAUTION A hazard that could result in light or moderate bodily injury or
damage to the device if the safety instructions are not followed.
CAUTIONS FOR HANDLING AND OPERATION
1.
①The Attachment is designed for hand use. Never install the Attachment or any hand tool on a
machine such as a special purpose machine, NC lathe or mill.
②Do not exceed the " Maximum Allowable Motor Rotation Speed " (Refer to " 6 - 1 Speci¿cations ").
③When sensing that the Attachment and motor / reducer, are overheated during operation, reduce
the working force or the motor rotation speed, or stop the operation until the Attachment cools
down before restarting.
④Do not touch the cutting tool while it is rotating. It is very dangerous.
⑤Wear safety glasses, dust mask and use a protective cover around the Attachment whenever the
Attachment is rotating.
⑥When installing a cutting 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.
⑦Do not use grindstones with an outside diameter over 20mm.
⑧Do not exceed 13mm of overhang for mounted grindstones as shown in Fig. 1. If the overhang
must exceed 13mm, reduce the motor speed in accordance with Table. 1.
⑨Do not use bent, broken, chipped, out of round or sub-standard cutting tools as they may cause
shatter or explode. The cutting tool with cracked, bended may cause some injury to operator.
When using a new cutting tool, rotate it in a low speed and increase speed gradually for safety.
⑩Always operate cutting tools within the cutting tool manufacturer's recommended speed limits.
Use of a cutting tool higher than the manufacturer's recommended speed limits could cause
damage to the spindle and injury to the operator.
⑪Do not apply excessive force. This may cause cutting tool slippage, cutting tool damage, injury to
the operator, loss of concentricity and precision.
WARNING

①KC - 300 and EKC - 300 are rotates the opposite direction of motor runs so that be aware of this
fact at the time of use.
②Do not drop or hit this Attachment, as shock can damage to the internal components.
③Be sure to clean the collet, the spindle taper and threads before replacing the 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.
④When cleaning an Attachment, stop the Attachment and remove debris with a soft brush or a cloth.
Do not blow air into the Attachment with compressed air as foreign particles or cutting debris may
get into the ball bearing.
⑤Always clean the cutting tool shank before installing the cutting tool in the spindle.
⑥When sizing the correct collet size to the cutting tool shank diameter, a tolerance of +0 〜
-
0.01mm
is strongly recommended.
A cutting tool shank within the +0 〜
-
0.1mm range is mountable, however, this may cause poor
concentricity and or insuf¿cient cutting tool shank gripping force.
⑦Select suitable products or cutting tools for each application. Do not exceed the capabilities of the
Attachment or cutting tools.
⑧Keep everything in order not to place the rag which could be caught near the Attachment.
⑨Stop operating immediately when abnormal rotation or unusual vibrations are observed.
Immediately, please check the content of section " 11. TROUBLESHOOTING ".
⑩Always check if the cutting tool and collet are damaged before and after operating.
⑪If the collet show signs of wear or damage, replace it before a malfunction or additional damage
occurs.
⑫No lubrication is required because grease impregnated ball bearings are used.
⑬After installation, repair, initial operation, or long periods of non operation, please carry out
break-in as follow. Start rotating slowly and over a short period of 5 - 10 minutes, increase speed
gradually until Maximum Allowable Motor Rotation Speed.
⑭Do not disassemble, modify or attempt to repair the Attachment. Additional damage will occur to
the internal components. Service must be performed by NSK NAKANISHI or an authorized service
center.
⑮When using this Attachment for mass production, please consider the purchase of an additional
Attachment to be used as a back-up in case of emergency.

7. CONNECTION OF THE ATTACHMENT TO THE MOTOR
Make sure your hands and all interlocking parts of the motor and the Attachment are clean before
connecting the Attachment to the motor. This is critical in preventing contaminants from entering the
Attachment or the motor.
CAUTION
Align the thread on the front end of the motor and the rear of the Attachment, and turn the Attachment clockwise.
If the drive shaft of the motor does not engage properly to the drive dog on the Attachment, it may only turn
approximately two threads before stopping. DO NOT FORCE THE TOGETHER. Loosen the Attachment from
the motor, rotate the bur by hand then re-try. The drive shaft and the drive dog must be fully engaged. When fully
engaged, secure the motor and Attachment using the provided wrench (Refer to the Table. 3).
8. CHANGING THE CUTTING TOOL
Do not tighten the collet without inserting a cutting tool or dummy bur, as this will result in damage to
the collet.
CAUTION
Please set the cutting tools to minimize the overhang amount. 13mm is the maximum amount of
overhang to maintain high accuracy and safety.
RECOMMENDATION
①Insert the rear of the Attachment Head into the Collet Wrench.
②Lightly hold the Collet Wrench and Attachment with ¿ngers. Place the Wrench (4mm) to the collet, slowly turn
the wrench (4mm) counterclockwise to secure.
③Turn the wrench (4mm) counterclockwise to loosen the collet with remove the cutting tool.
* The cutting tool cannot be removed by turning the collet with the wrench, unless the collet is secured to the
Collet Wrench.
In this case, repeat procedure ①- ②to secure the collet to the Collet Wrench.
④When mounting the cutting tool, turn the wrench (4mm) clockwise to tighten the collet after securing the collet
to the Collet Wrench, then secure the cutting tool.
