CBN Inserts

CBN Inserts (Cubic Boron Nitride Inserts) are advanced cutting tools engineered for machining hardened steels, cast irons, and superalloys with extreme hardness. Second only to diamond in hardness, CBN provides outstanding thermal and chemical stability, making it the tool of choice for high-speed finishing operations in difficult-to-machine materials. Available as solid CBN or CBN-tipped inserts, these tools deliver excellent edge retention and dimensional accuracy in demanding machining environments.

CBN inserts excel in operations where carbide tools fail due to excessive wear or thermal degradation. They enable high-speed cutting with superior surface finishes, reducing the need for grinding and secondary processes. Common geometries include both positive and negative rake designs, optimized for turning, milling, and grooving applications. Coatings and edge treatments further enhance tool performance, extending life even in continuous production cycles.

The applications of CBN inserts are concentrated in industries that machine extremely hard materials. In automotive manufacturing, they are used for finishing hardened gears, shafts, and bearing surfaces. Aerospace sectors rely on CBN to machine high-strength nickel alloys and turbine components. Tool and die industries use them for finishing molds and dies made of hardened steel, while energy and power generation industries employ CBN inserts for machining wear-resistant components under high loads.

Performance depends on selecting the correct grade and insert design. Low-content CBN inserts are cost-effective for moderate hardness, while high-content CBN inserts offer maximum durability for extreme conditions. Stable machining conditions, correct feeds and speeds, and proper coolant use are vital to achieving the best results with CBN tooling.
