Indexable Milling Grades Offer Higher Wear Resistance
July 1, 2022
Available for many indexable milling product lines, the new KCK20B and KCKP10 grades come with a golden top layer for easy wear identification, providing maximum tool life for each cutting edge.
Kennametal has introduced the KCK20B and KCKP10 indexable milling grades for higher wear resistance and up to 30% longer tool life when machining cast iron and compacted graphite iron components. Both grades offer higher productivity and consistent, repeatable performance during roughing, semi-finishing and finishing operations, according to the company.
"The new grades feature High-Power Impulse Magnetron Sputtering (High-PIMS) technology that provides a smoother insert surface and optimal layer adhesion for less flank wear-one of the leading causes of insert failure," said Gil Getz, Product Manager, Kennametal. "The new coating technology also increases cutting edge strength. The result is high-performance milling in a broad range of cast iron alloys, including grey cast iron, ductile cast iron and compacted graphite cast iron."
KCK20B and KCKP10 are suitable for wet or dry cuts. These include rotor hubs used in windmills, pump housings, steering knuckles and gear housings for heavy equipment, and automotive components like crankshafts and cylinder heads. While KCK20B offers higher productivity in roughing and semi-finishing operations, KCKP10 is applicable for finishing operations, and also works well when profiling and copy milling cast iron and steels up to 45HRC.
"For applications where high tooling cost and downtime associated with tool changes are especially important, KCK20B and KCKP10 grades can increase tool life tremendously," said Getz. "And for those who wish to increase throughput, the new grades deliver there as well. Either way, it is a win-win for any shop machining cast iron."
