High Speed Cutter for Aluminum Alloy
RF Type
■ General Features
The high-speed RF type cutter for aluminum alloy is a light-weight, high-efficiency cutter
designed for roughing to finishing of aluminum alloys and other non-ferrous metals.
■ Work Material

（ ）
● Aluminum and aluminum alloy Not suited for cast
● Other non-ferrous metal iron or steel
■ Characteristics
● From Roughing to Finishing Processes：Roughing : Economical carbide insert / High-precision finishing with SUMIDIA
● Strong and Light Cutter Body：Special Aluminum body / 40% lighter than steel cutters / Hard-anodized plated body /
Improved efficiency in higher rotational speeds, lower spindle loads and shorter tool change time
● Safe Design：Anti-centrifugal force design to prevent inserts from dislodging from cutter (Speeds must be within max. recommended conditions) /Non-wedge design to prevent deformation
● Easy Run-out Adjustment：External setting gauge is used for easy tool presetting / High precision cutter construction, units fitted are within 10 μm even before setting
■ Application Examples ● Maximum Allowable Spindle Speed

As it is possible to mix different types of inserts / blades, it is important
Cover to take note of the following.
RFC ● Do not mix reground and new inserts or even inserts with different
regrinding amount on the same cutter.
● Carbide and SUMIDIA inserts must be arrange in an alternate manner.
Screw ● Ensure proper balancing by fixing SUMIDIA inserts of blades on
FBUP2-A0-8 opposite positions of the cutter.
