PCBN Tooling

The second hardest of the polycrystalline tool materials, PCBN (Polycrystalline Cubic Boron Nitride) has a superior thermo-chemical stability to that of the diamond-based material, PCD, and is therefore recommended for machining hard ferrous materials of between 45 and 60 Rockwell (HRC), where the chip softening produced by the cutting heat reduces the amount of cutting energy required and promotes chip removal.

High content PCBN tools (N.I.D. grade C20) are preferred for operations such as rough and intermittent cutting, while low content PCBN tools (N.I.D grade C10) are recommended for fine and finish cutting.

As well as making specialist tooling to order, such as end mills, slot drills and ball end cutters, Nixon Industrial Diamonds Ltd also manufactures a wide range of standard ISO inserts.
