RFHigh Speed Cutter for Aluminum Alloy

  • 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 /Non-wedge design to prevent deformation

(Speeds must be within max. recommended conditions)

  • 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

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.
