Following the introduction of its newly developed IG3I substrate, Horn is optimizing its DS solid carbide end mills to enable productive, cost-effective machining of titanium and its alloys. By combining the novel carbide grade with a new coating, the tool specialist has been able to increase cutter life significantly.
Sharp micro-geometry on the cutting edges, positive rake angles, large clearance angles and polished flutes prevent strain hardening of the workpiece and built-up edges on the rake faces of the mill when machining titanium. Variable helix angles and different tooth pitches ensure quiet, low-vibration milling.
The new coating demonstrates very high layer adhesion, ensuring good 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, which demonstrates homogeneous wear.
DS titanium milling cutters were developed based on the tried-and-tested solid carbide milling cutters in the DS system, which for years have been used to machine soft and hardened steels, chromium-nickel steels and superalloys as well as copper, aluminium, plastics and fibre-reinforced plastics.
