High-Performance Carbide End Mills Offer Extended Tool Life

Greenleaf Corporation has announced Greenleaf-360, a new line of high-performance solid-carbide end mills to complement the XSYTIN-360 line of solid ceramic end mills. Greenleaf-360 end mills combine a proprietary flute design with a high-performance carbide substrate, which is said to enable fast and efficient material removal with less stress induced into the part. According to Greenleaf, a combination of strength, toughness and heat resistance enables machining capabilities from roughing to finishing with extended tool life and predictability. Greenleaf-360 high-performance end mills have reportedly shown speed and feed performance 25-50% higher than the competition with extended tool life.

Greenleaf-360 end mills use a substrate that is capable of machining in a wide variety of materials, from low carbon steel alloys to heat-resistant alloys. The sub-micron grade provides great toughness and wear resistance that offers customers one grade that can be applied in many different applications.
The physical vapor deposition (PVD) coating that is standard on all Greenleaf-360 end mills reportedly provides added productivity and performance. The coating offers a very low coefficient of friction with an extremely high service temperature range. This combination results in high wear resistance and enables for higher speed capabilities, especially in heat-resistant alloys.

Unique features and benefits of Greenleaf-360 end mills include a proprietary flute design that reduces cutting forces and provides maximum material removal; a full line of four-, five- and seven-flute configurations that provides solutions from full slotting to high-speed machining; extended shank length options that enable effective completion of long-reach applications; high-performance substrate and coating combination that offer versatility in machining various workpiece materials; and regrind capabilities to like-new condition for added cost savings and value.

The Greenleaf-360 inch and metric end mills are said to be ideally suited for machining materials in the aerospace, automotive, die & mold, medical and power generation industries.
