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.
Comparison of Tool Life between CBN and Coated Tools
A CBN tool provides stable surface roughness even after machining 30 workpieces!
