New Beyond Grades from Kennametal Add Productivity to Turning Hard Alloys

(LATROBE, PA) – Because of their high performance strength and relatively light weight, high-temperature alloys are growing in applications across many manufacturing industries, notably aerospace and defense, automotive, heavy equipment, and energy.

Higher-temperature-strength materials, however, also mean high cutting forces when machining.  Titanium, for example, also exhibits high work hardening and a large strain rate, which also raises temperatures and the energy required to remove the chip. In most applications, the answer means slower speeds and feeds, since a carbide cutting tool’s strength decreases as temperatures increase.

New Beyond™ grades from Kennametal are delivering higher productivity for turning tough alloys, both in higher speeds and feeds (faster turnaround time) and longer tool life (more parts per tool). KCU10™ is specifically engineered for increased performance in OD and ID turning, grooving, plunging, undercutting, and threading. KCU25™ covers threading, grooving, cutoff, and selected additional turning applications.

Both take advantage of new PVD (physical vapor deposition) coating technology, including special surface treatments that improve machining performance in high-temperature materials. In many cases, speeds, feeds, or depth-of-cut can be increased, while related wear issues like depth-of-cut notching are reduced.

KCU10 additionally features a dual-layer coating application, a top layer of AlSiTiN atop a second layer of AlTiN. The boundary between the two serves to help deflect micro-cracks
