High Speed Aluminium Alloy Cutter 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, enables run-out within 10 μm even before setting ■ Application Examples ● Maximum Allowance of Spindle Speed Work Cutter Cutting Conditions Cat.

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. M36
