Greenlead Xsytin-360 End Mills

Greenleaf Corporation has introduced a line of solid ceramic end mills: Xsytin-360. The end mills are composed of Xsytin-1, which allows users to apply chip loads similar to solid carbide end mills with higher speeds common to ceramic machining, according to the company.

Greenleaf’s Xsytin-1 material was designed to provide high wear resistance and thermal shock resistance. According to the company, Xsytin-360 end mills have shown high material removal rates and resulted in increased productivity on a range of materials. These end mills are suitable for machining a variety of materials, including high-temperature alloys, 3D-printed sintered high-temperature alloys, hardened steels, ductile cast irons and compacted graphite iron (CGI). Greenleaf states that, in hardened steels, Xsytin-360 end mills have tool life equal to high-performance carbide end mills when run at high-end speeds (11,460 RPM), while also removing over 73 cubic inches of material.

According to Greenleaf, features include: 

  • A flute design that is reported to minimize cutting forces, reducing vibrations and optimizing tool life
  • High strength and wear resistance at extreme feed rates
  • Four-flute design for maximum material removal in slotting, pocketing and profiling applications
  • Regrind capabilities
  • A broad application range
  • Increased feed rate capability and broad speed range
  • Increased material removal rates (MRR) of 100% over carbide

The mills are suitable for machining materials in the aerospace, automotive, die and mold and power generation industries.
