1.刃具をコレットに挿入し、ナットを手で軽く締め込んでください 
 
2.主軸の六角穴(NBS6タイプは六角凸)とナットの両方に付属のスパ
 ナを掛けて締め付けてください。 

・刃先方向の角度調整の際は、刃具の刃部は危険ですのでウエス等を
 添えてください。 
 
 
・ロックボルトを締め付けた状態でも、本体ケースとヘッドケースと
 の間にあるプレート(目盛り刻印のあるパーツ)にスキマがありま
 すが、構造上のスキマですので問題はありません。 
 

CAUTION

ご注意 

3-1

機械にアングルヘッドを取り付けた状態で、5本のロックボルトを少しだ

  けゆるめます。(図1) 
 

3-2

刃具に十分注意をし、ヘッドケースを任意の角度に旋回させます。 

 (内部にOリングが入っておりますので旋回させるのには少し力が必要にな 
  る場合があります。) 
 
 

3-3

ロックボルトを締め付ける場合は、付属のLレンチで機械締め(対角線の

  ボルトを互いに締める)で均等に締めてください。

Loosen the 5 lock bolts (Fig. 1) while ANGLE HEAD is mounted in a machine spindle.

Turn the head casing up to a certain angle.  Be aware of a cutting tool at this  moment.  
(Large force may be needed to turn the head casing due to an o-ring inside.)

Tighten the 5 lock bolts in the way that a pair of the bolts positioned diagonally is 
 tightened with one another using an L-shaped key wrench attached.

Check the accuracy of the angle adjustment with a dial indicator, etc. on the  reference 
faces.(Fig. 2)

When adjusting the angle of a cutting edge, cover a cutting edge with a waste, 
etc. to  prevent cutting yourself.

Even though the lock bolts are tightened, there are clearances on a plate (a 
part with a  marking of graduations) between the body casing and the head 
casing. They are structural clearances that have no problems.

Insert a cutting tool into a collet, and tighten a nut lightly by hand.

Hook and tighten attached spanners on both of a hexagonal hole of the head's 
spindle  (a hexagonal head for NBS6 type) and the nut.
