For gray iron and CGI, Kennametal’s new flexible, cost-effective and user-friendly milling cutter is ideal for any type of CNC machining center.
The new Kennametal face-milling platform for cast iron applications, the KCFM 45, provides the option for semi-finishing as well as fine-finishing applications, exceeding the highest surface quality requirements. With carbide, ceramic, and PcBN inserts, this tool is a flexible, cost-effective, and user-friendly solution that is ideal for any type of CNC machining center.
Carbide inserts are ideal for machining at lower RPM, or in thin-walled workpieces and less stable conditions, while ceramic inserts (KY3500 grade) provide elevated surface speeds resulting in higher productivity. Both offer excellent performance. For fine finishing operations, PcBN inserts will deliver the best possible surface finish, tool life, and throughput.
The inserts are positioned at a positive axial angle, but with a slightly negative radial angle for better tool life. That creates significantly lower machining forces than competing cast iron face mills, helping to eliminate chatter and further improving surface finishes.
The KCFM 45 is recommended for cast gray iron and CGI applications, semi-finishing, and fine-finishing operations. The KCFM 45 uses a combination of hexagonal semi-finishing inserts in the fixed pockets together with square finishing inserts in the adjustable pockets with cartridges.
