Tungaloy is adding 177 new shapes and geometries to its BXA20 line of coated T-CBN inserts designed for turning hardened steel parts.
The BXA20 insert has a nano-multilayered PVD coating, which has the twice as thick as conventional grades, and coated on a PCBN substrate. This adds wear and fracture resistance to the grade for longer tool life and improved predictability in continuous to interrupted cuts of hardened steel.
New shapes and geometries include -L, -LF, and -LC style edge preparations in addition to existing standard and -H edge preparations to address various needs of hard turning operations.
At a glance:

- hard turning
Single-point cutting of a workpiece that has a hardness value higher than 45 HRC.
- physical vapor deposition ( PVD)
physical vapor deposition ( PVD)
Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.
- 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.
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.
