Ball Nose Mills for Difficult-to-Cut Materials

Greenleaf Corp. said its new line of Excelerator Ball Nose Mills is the only complete line of ball-nose cutters designed to use both ceramic and carbide inserts in the same qualified cutter bodies. The company also said the cutter geometry combined with ceramic or carbide inserts offers higher performance, longer tool life and better cutting action over competitors’ mills across a wider spectrum of materials.

The ball nose insert geometry prevents excess tool pressure at high metal-removal rates and has the edge strength to shear material without smearing. Greenleaf’s WG- 600 ceramic and G-925 carbide inserts maximize tool life when machining a wide variety of difficult materials including nickel- and cobalt-based super alloys, hard steels, soft steels, stainless steels, titanium and more. The cutter line is available in standard- and extended-length versions.
