Specialized High-Speed Cutting Tools Designed for Difficult Materials

Horn USA’s CBN Tool System offers reliable machining for problematic materials which require a high level of machining expertise, including nickel-based alloys, titanium and cobalt-chrome. These specialized tools enable moldmakers to create high surface quality on workpieces.

The geometries are specially developed for finishing and ensuring high surface quality, tight tolerances and high process reliability when machining material groups P, K and S. The company says it is pushing the boundaries of machining speed with this system.

In operation, the tools achieve speeds of 350 m/min (1,148 ft/min) when cutting Inconel and 300 m/min (984 ft/min) 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.
