Hardcut™
TiSiN coating for extreme cutting conditions
Hardcut™ TiSiN is engineered for high speed machining of hard materials at minimum or zero lubrication conditions. The coating is designed to allow a cutting edge temperature of up to 1100 °C. A distinguishing feature of Ionbond’s Hardcut™ is its composition: a multi-layer coating with a nano-composite outer layer with Si3N4 nano-crystallites in a crystalline TiN matrix. This matrix is designed to protect the cutting edge from heat transfer, oxidation and abrasion.
Hardcut™ can be used on work piece materials that include steels of up to 60 HRC, high nickel content alloys and titanium. Hardcut™ is particularly suited for carbide end mills and gear cutting tools for semi-finishing and finishing operations that involve high temperatures at the chip/cutting edge interface. The cutting speeds generally range from 100 to 300 m/min, depending on cutting conditions and work piece material.
