South Korea – Improving productivity in complex shaped component machining and high-speed cutting is a challenge for cast iron. To overcome this, and flank and crater wear, notch wear as well as build-up edges caused by abrasion, adhesion and diffusion, Taegutec has introduced the TT7505 grade for high-speed grooving applications on cast iron.
According to the metalworking company, this grade meets the hardness and toughness requirements needed for cast-iron machining. TT7505 has been optimised for high-speed cast-iron machining, including continuous cutting applications while guaranteeing stability and longer tool life, Taegutec says.
Another advantage of this grade is the application of a special CVD coating technology and a newly developed substrate for improved wear resistance and toughness for overall better performance.
Taegutec says that in several case studies TT7505 grade increased tool life by 25% when machining ductile cast iron GGG 40.3 and 13% in gray cast iron of GG 35 materials.
