Series
Key Point on Machining
a When milling titanium alloys adhesion is easily generated, thermal
conductivity is low and heat concentrates on the cutting edge, it is important
to remove heat at the cutting edge efficiently and also to evacuate chips
smoothly. The Coolstar series achieves optimum cooling effect and chip
removal due to the multi coolant holes and unique flute shape. Stable
machining became possible for difficult-to-cut material applications.
Application Example
a
No adhesion due excellent cooling effect of the
multi coolant holes.

(TOOLS NEWS B182G)
Key Point on Machining
a When rough machining titanium alloy, chipping and abnormal damage of the
cutting edge easily occurs if low rigidity tools are used. Using high rigidity
tools and low cutting resistance inserts is recommended. Stable machining
is possible because the VFX series is a high rigidity design and cutting
resistance is lower due to the convex curve cutting edge and the V-formation
of the clamping face.
Application Example
a
Over 7 times tool life is achieved in combination
with high-pressure internal coolant.
