Processing characteristics of titanium alloy : small thermal conductivity, high cutting temperature; short contact length between chip and rake face, large tool tip stress; high strength, high hardness and high impact toughness of titanium alloy, work hardening is very serious; The friction speed is high; the titanium and titanium alloys have high chemical activity at high temperature, chemically react with oxygen and nitrogen in the air to form a brittle layer and reduce plasticity; the elastic modulus is small, and rebound is easy to occur.
The introduction of two new grades of Sandvik Coromant S30T and S40T takes titanium machining reliability and blade life to a new level, which can be used for face milling, shoulder milling, long edge milling and high in the CoroMilll milling cutter family. Feed milling, plunge milling, profiling and slot milling.
Sandvik Coromant CoroMill Milling Cutter
The S30T increases milling speed and tool life. It combines the characteristics of micro-grain carbide and wear-resistant PVD coatings. The sharp cutting edge has strong fatigue resistance and micro-crack resistance.
The S40T is used for difficult milling conditions and the S40T was developed for difficult milling conditions. It consists of a high-toughness cemented carbide and a thin CVD coating that withstands vibration and other difficult conditions during cutting and has longer cutting times. In addition, the cutting edge is gradually blunt rather than cracked, so wear is predictable.
