SpheroX Ball Nose End Mill

The new generation of SpheroX milling cutters opens up some impres- sive new prospects: Where classic HSC machining reaches its limits, new performance horizons can be opened up with HDC machining processes. The SpheroX has been designed for HDC processes and impresses with its high stock removal rates, which can significantly increase productivity compared to conventional milling cutters. The new SpheroX milling cutters have been developed specifically for high-performance roughing and finish- ing of hard and high-hard steels such as HSS. The tools provide excellent results in the machining of deep-drawn, injec- tion, and die-cast molds, but also in the forming of solid stock. The range of materials they can be used for includes steels in the hard- ness range from 50 to 70 HRC. The spherical radius, with a tight tolerance of +/–0.005 mm, is the basis for the dimensional accuracy of the new SpheroX milling cutters . Thanks to the four cutting edges, high feed rates can be achieved. Penetration operations with a penetration angle of up to 5° are also no problem for these new tools thanks to their special edge geometry. The cutting edge length and the flute geometry facilitate HDC machining with high axial infeeds at very high feed rates. This means that even deep cavities can be machined extremely efficiently. The new DURO-SI coating reduces tool wear and guarantees long-term dimensional accuracy of the workpiece. This results in a large increase in pro- ductivity. The new SpheroX generation features universal utilizability, high productivity and long tool life. Highly productive 3D milling technology with SpheroX milling cutters The advantages: • High productivity thanks to higher axial infeed and very high feed rates. • Low tool costs thanks to improved wear resistance and high surface finish qualities, which significantly shorten subsequent polishing pro- cesses. • Improved component quality thank to the high- precision ball with a tolerance of just +/–0.005 mm. The shank is ground to an h4 tolerance. • Universal application range thanks to improved penetration capabilities and the tools’ excellent suitability for HSC and HDC strategies. [ 2 ]
