Improved cutting edge delivers next generation small parts machining. The PVD coated MS9025 grade has improved thermal conductivity by optimising the grain size and reducing the boundary contact between the carbide particles. This optimisation reduces the temperature of the cutting edge during machining. The even surface of the coating has been achieved by first making the carbide substrate smooth then by promoting straight growth of the coating crystals. This leads to excellent welding resistance. The high Al-rich (Al,Ti)N single layer coating provides stabilization of the high hardness phase and succeeds in dramatically improving wear, crater and welding resistance.
