6-6. Feeding Speed
Be sure you should avoid quick feeding or heavy
shock. Please refer to Fig. 12.
Stainless Steel 3cm/sec
Mild Steel 2cm/sec

6-7. When Exhaust Freezes
When you continuously chamfer more than 1m,
the number of the rotation of the tool sometimes
becomes fewer because of frozen exhaust. Since
the fewer number of rotation leads to the damage
of the Indexable Inserts, machine the workpiece of
more than 1m as shown in Fig. 13. If it shows the
sign of frozen exhaust, put away the rotating tool
from the workpiece for the period of 3 seconds. The
rotation will return to the original.

6-8. How To Operation
WARNING
●
Always turn off the air supply and disconnect
the air supply hose.
●
The workpieces should be fixed as mach as
while working possible.
(1) Select the chamfering level.
(2) Make sure that the Valve is set at "OFF" position
and connect the air hose to the tool.
(3) Hold the Housing up. Start the tool.
(4) Hold the Housing and Knob firmly. Apply the tool
on to the workpiece along with the direction A
(shown on the Plate A ) carefully.
●
In case of chamfering stainless steel, chamfer deep
to the desired chamfering level by one span of
operation. Repeat of chamfering marks the life of
Indexable Insert shorter.
6-9. Radius Chamfering
●
By using radius chamfering Indexable Inserts, radius
chamfering job can be done.
●
Radius cutting Indexable Insert is an optional
accessory.
(1) Select the radius chamfering.
(2) Make sure that the Valve is set at "OFF" position
and connect the air hose to the tool.
(3) Hold the Housing up. Start the tool.
(4) Hold the Housing and Knob firmly. Apply the tool
on to the workpiece along with the direction A
(shown on the Plate A) carefully.
※On Tangential Line Cutting
●
Because of the constructional reason, it is possible
to make a radius tangential line cutting on the
side facing the Plate B by adjusting the Head, but
impossible on the upper side facing the Plate A. For
making a radius tangential line cutting on the upper
side,conduct in a following manner.
① Place the tool on workpiece with Plate A on upper
surface of workpiece and Plate B on side surface,
as indicated in Fig.14. Then, turn the Eccentric
Ring to adjust the Indexable Inserts to cut properly
side surface, and conduct the first cut (see Fig.15).
② Next, placing Plate A on side surface and Plate B
on upper surface, conduct the second cut.
③ In this case, slight seam may be left in center of
chamfered surface (Fig.16).
