The new CBN600 universal PCBN insert grade from Seco Tools LLC brings cost-effective performance to high-volume rough turning operations that involve gray cast iron, high chrome iron and high manganese steel workpiece materials.
This solid insert combines 90 percent CBN content, a multi-modal grain size and an Al ceramic binder to easily tackle abrasive workpiece materials, heavy cutting forces and high levels of thermal shock for varying depths of cut conditions.
Developed to complement Seco's premium CBN300 and CBN500 grades, CBN600 encompasses nine standard products with double-sided inserts available in round, rhombic and square styles.

- cubic boron nitride ( CBN)
cubic boron nitride ( CBN)
Crystal manufactured from boron nitride under high pressure and temperature. Used to cut hard-to-machine ferrous and nickel-base materials up to 70 HRC. Second hardest material after diamond. See superabrasive tools.
- polycrystalline cubic boron nitride ( PCBN)
polycrystalline cubic boron nitride ( PCBN)
Cutting tool material consisting of polycrystalline cubic boron nitride with a metallic or ceramic binder. PCBN is available either as a tip brazed to a carbide insert carrier or as a solid insert. Primarily used for cutting hardened ferrous alloys.
- turning
turning
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
