Greenleaf Solid Ceramic End Mills Maximize Material Removal

Greenleaf Corporation showcases its Xsytin-360, a line of high-performance, solid ceramic end mills, in live milling demonstrations at Eastec 2023 in booth 5317. Xsytin-360 end mills combine Greenleaf’s Xsytin-1 substrate with a unique cutting geometry that is said to offer up to 10X higher productivity. The strength of the material enables the user to apply chip loads similar to solid carbide end mills with higher speeds common to ceramic machining.

According to Greenleaf, Xsytin-360 end mills show the highest material removal rates and results in increased productivity on a wide range of materials, including high-temperature alloys, 3D-printed sintered high-temperature alloys, hardened steels, ductile cast irons and compacted graphite iron (CGI). In hardened steels specifically, the tool life of Xsytin-360 end mills has shown to be equal to high-performance carbide end mills when run at high-end speeds (11,460 rpm), while also removing over 73 cubic inches (over 1,200 cubic cm) of material.

Xsytin-360 end mills include a four-flute design that is said to minimize cutting forces, reduce vibrations, optimize tool life and provide maximum material removal in slotting, pocketing and profiling applications. The overall length of the end mills enables for regrind capabilities, and their broad application range means numerous machining centers are capable of running these end mills.
