CBN End Mill
The most suitable end mills for long-hour finishing process of high hard materials. End mills made of CBN sintered compact with hardness one rank below of diamonds as a raw material for tools.
What is CBN Sintered Alloy?
CBN (Cubic Boron Nitride) sintered alloy is second hardest material next to diamond as left figure, 3 times harder than Tungsten carbide, moreover having features of strong heat-resistance and high thermal conductivity. However, less tough characteristic of CBN often causes chipping of tool edge easily. Accordingly, CBN is recommended for finishing of hard materials with less cutting load on the tool edge, which guarantees extra-long tool life.
Rich Lineup, Suitable to Various Machining
End mills of the next generation realized by developing a unique tool shape utilizing the characteristics of the CBN sintered compact with high hardness and thermal resistance and establishing grinding technology. Long life and stable finished surface are provided in finishing process of high hard materials.
