Nickel-based alloys, titanium, cobalt-chrome: Reliable machining of these problematic materials requires a high level of machining expertise. If the workpieces also require high surface quality, the use of specialized tools is essential. HORN addresses this need with a cubic boron nitride (CBN) tool system that is unique to the market. Geometries specially developed for finishing and ensuring high surface quality, tight tolerances and high process reliability when machining the ISO material groups P, K and S (steel, cast iron, super alloys). HORN is pushing the boundaries of machining speed with this system.
In operation, the tools achieve speeds of 350m/min (1,148fpm) when cutting Inconel and 300 m/min (984fpm) when cutting titanium alloys. The tools produce surfaces with an almost mirror-like finish. The combination of cutting material, quality of the tool edge grinding, coating, and coolant supply enables the high performance. The reliable process is enhanced by the linear wear behavior of the CBN cutting material. Wear rate is therefore predictable. The finishing system is available as standard in numerous HORN tool systems. In addition to various ISO inserts, HORN offers CBN inserts for the Supermini, Mini, 229 and 315 systems, and for the DTS milling system.
