American National Carbide has improved its grades designed for machining steels across the ISO P classification, from finishing to heavy roughing. All three negative-rake turning inserts in the P series have been reformulated to improve cutting characteristics and performance.
Grade AN3015 for finishing applications features a hard alloyed gradient substrate along with a multi-layered aluminum oxide CVD coating, enabling machining at higher speeds with resistance to flank wear and plastic deformation.
General-purpose grade AN3025 for machining alloy steels features a multi-layered oxide coating over a cobalt-enriched substrate for wear resistance and toughness at higher speeds.
Grade AN3035 for roughing is now more robust with a higher binder content and cobalt-enriched alloyed substrate. A multi-layered aluminum oxide coating provides toughness required for machining in unfavorable conditions, such as scale and interruptions, and with heavy depths of cut.
Editor PickPCD Face Milling System’s Diameter Cuts Large Parts in Fewer Passes
The KBDM polycrystalline diamond (PCD) face milling system from Kennametal is designed for high-volume machining, with standard sizes ranging from 2.5" to 8.0" (63 to 200 mm) and cutter diameters ranging to 21.5" (550 mm).
