ISO Tools for Milling

MAPAL offers a broad portfolio of ISO Tools for Milling operations. A new series of cutting materials has been developed specially for the milling of cast iron that covers the whole bandwidth of grades – GJL, GJV and GJS. Preliminary results show that the new cutting materials allow not only a significant increase in tool life and hence greater cost-effectiveness, but also higher cutting speeds and therefore maximum productivity. The cutting material series is based on newly developed carbide substrates. The structures of the carbides have been modelled in such a way that they provide an optimum relationship between ductility and wear resistance. The cutting material series includes three PVD-coated carbides and two CVD-coated grades. The PVD coating here consists of an optimised TiAlCrN with very fine structuring of the layers to create an optimum relationship between ductility and hardness/wear resistance. The CVD coating is based on an MT-TiCN with an alpha-Al2O3 top coat. This layer combination offers not only high wear resistance, but also good thermal stability. A special post-treatment has been developed for both the PVD coating and the CVD coating that ensures an extremely smooth surface and hence an optimum chip flow. This minimises tribochemical wear.
