VII. The use of the Positioning Shelf
1. Preset the scale of the positioning shelf.
●
Right Positioning Shelf :
Φ
3.0 mm -
Φ
12.0 mm (Fig. 7-1)
①
Turn it by clockwise to the end.
②
Turn it by counterclockwise at “0”.
●
Left Positioning Shelf :
Φ
12.1 mm -
Φ
16.0 mm (Fig. 7-2)
①
Turn it by clockwise to the end.
②
Turn it by counterclockwise at “10”.
2. Adjust the scale according to end mill’s material.
●
Adjustment for carbide material end mill :
Adjust according to end mill’s cutting diameter.
Eg: 10.0 mm end mill, set at 10.
●
Adjustment for HSS material end mill :
Decrease 1-3 scales according to end mill’s cutting diameter.
Eg: 8.0 mm end mill, set at 5-7.
3. Align Slot No.1 of the clamping nut to the pin on the positioning
shelf, insert the chuck set into the positioning shelf and
fit them with no gaps, then turn the chuck set clockwise
until it stops by the pin. (Fig. 7-3 step
�
)
4. Push end mill to the end and slowly turn it clockwise until
end mill’s longer cutting edge stops by the position block.
(Fig. 7-3 step
�
)
5. Turn the collet holder clockwise and tighten the chuck set
to secure end mill. (Fig. 7-3 step
�
)
6. Gently turn the chuck set counterclockwise and take it out.
7. After taking out the chuck set, make sure end mill's longer
cutting edge is parallel to the Slot No.1 of clamping nut
(See Fig. 6-4)
※
If it is not parallel, adjust the scale
(Fig. 7-4) and reposition end mill.
