Horn to launch expanded DS range at EMO Milan

1 min read

​Horn will launch at EMO 2021 its expanded DS range of solid carbide end mills with new, high performance geometry. The system has been designed for use in HPC (high-performance cutting) milling of high strength steels at high material removal rates.

It particularly excels in dynamic roughing applications as well as in standard roughing cycles. Different helix angles create an irregular tooth pitch, making operation exceptionally smooth.

The tools’ optimised face geometry reduces the cutting pressure during linear or circular ramping. Improved chip spaces ensure optimal process reliability during chip formation and removal. The system also demonstrates good performance during finishing. Smooth operation means that high surface quality can be achieved during side milling, for example.

HPC milling of high strength steels at elevated rates of metal removal places significant demands on the tools. New carbide substrates and new tool coating technologies make this process feasible. Horn relies on the ES3P grade with a HiPIMS coating for its milling cutters.

High power impulse magnetron sputtering technology offers several advantages and new possibilities when it comes to coating precision tools. It enables the formation of coatings that are dense and compact, as well as extremely hard and tough.

The coatings have a homogeneous structure and exhibit a uniform coating thickness, even on complex tool geometries. They also demonstrate good layer adhesion, ensuring cutting edge stability. Thanks to its high temperature resistance, the coating serves as a heat shield and reduces the amount of heat transferred to the carbide.
