Kennametal Introduces the KCFM™ 45 Face Milling Cutter

Insert offering

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.

“With the KCFM 45 face milling cutter, users can mix and match different insert options to suit the application requirements and machining conditions,” says Michael Hacker, Product Manager,
Kennametal. For example, you might 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 the configuration, the KCFM 45 exceeds the highest surface requirements.

Wave killer

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 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.),” says Hacker. The KCFM 45 is ideal for gray cast iron, CGI applications, semi-finishing and fine-finishing
operations.
