Featuring fixed and adjustable pocket seats, the KCFM 45 face milling cutter from Kennametal Inc. (Pittsburgh, PA) allows for CGI applications as well as semi-finishing and fine-finishing operations in cast iron. With carbide, ceramic and PcBN inserts, the tool is a flexible, cost-effective and user-friendly solution 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. Ceramic inserts (KY3500 grade) provide elevated surface speeds, increasing productivity. PcBN inserts deliver the best possible surface finish, tool life, and throughput in fine-finishing operations. Thus, users can mix and match inserts to suit application requirements and machining conditions. For example, the operator could use PcBN finishing inserts in the adjustable pockets and ceramic or carbide inserts in all other pockets for wet machining or lower-volume applications. Regardless of configuration, the tool exceeds the highest surface requirements.
The wave-killing 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 with its adjustable pocket seats can generate surface finishes of 0.8µm Ra (32 µin.) or better, and waviness lower than 10µm Wt (400 µin.).
