2 Rough milling in hard and high-hard materials [ 2 ] You want to machine very hard steels with a hardness rating higher than RC? And to do so quickly, efficiently and safely? Then our new cylindrical X-NVS roughing mill is the ideal solution. It s ideally suited to PC and DC machining of high-hard steels. These specially developed tools are roughing tools that also have excellent penetration capabilities. Penetration angles of up to are possible, these being times greater than the values of conventional milling cutters used to machine hardened steels. Our smooth-cutting X-NVS mill is ideal for machining hard materials for the worlds of mold-making, punching and stamping. The newly developed geometry of our X-NVS mills and the new Duro-Si coating combine to faci- litate high material removal rates and a long tool life when machining steels with a hardness rating in excess of RC. Thanks to the perfect combination of robust, penetration-capable edge geometries and high-hard and highly wear-resistant coating systems, these tools offer significant advantages over conventional rivals. When the demands for rapid roughing of grooves, inner and outer pockets and complex two-dimensional contours are high, X-NVS mills reveal their true potential resulting in greater productivity gains and lower tool costs compared with conventional tools. The benefits: Greater productivity thanks to an improved penetration capability with penetration angles of up to Greater flexibility thanks to high infeed rates in the axial and radial directions igh rigidity also facilitates PC applications Shorter machining times thanks to the ability to perform DC applications Low tool costs thanks to a long tool life

3 Product innovations for greater efficiency and lower costs: Comparison of tooth widths Newly developed cutting edge geometry The X-NVS tool concept differs from that of conventional milling tools primarily with regard to the new cutting edge geometry that has been specially developed with high-hard steels in mind. In combination with the new Duro-Si coating, this tool concept is an outstanding solution for roughing steels with hardness ratings greater than RC. Robust, polished tooth edge enables high tooth loads and consequently high feed rates Up to % higher material removal rates The polished tooth edge precisely matched to the load profile and the solid tooth stabilie the cutting edge and help prevent break-outs from occurring during the chip formation process. This stabiliing effect is reinforced by the new, extremely hard Duro-Si coating. This can increase the material removal rate by up to % compared with a conventional tool. Thanks to the enlarged concave profile, the mills can be used for penetration operations with angles of up to. This also enables inner pockets to be milled out cost-efficiently. The concave profile is suitable for penetration operations with angles of up to Comparative productivity increase (material removal rates) [%] 1 + % [] 0 Conventional X-NVS Longer tool life By combining a conditioned cutting edge and Duro-Si coating with a very fine-grained carbide that offers very good edge stability, tool life can be increased considerably. What s more, the cutting edges suffer from very little wear and retain extremely good cutting performance even after a long time in use. Comparative wear: in material (0 RC) Conventional X-NVS Duro-Si Material: (0 RC), Vc = 0 m/min, n = 000 rpm, vf = 00 mm/min, ap = 9 mm, ae = 0. mm, tool dia. = mm, t = min Comparative wear: in SS material ( RC) Conventional X-NVS Duro-Si Material: SS ( RC), Vc = 0 m/min, n = 200 rpm, vf = 900 mm/min, ap = 9 mm, ae = mm, tool dia. mm, t = min

4 The advantages of our X-NVS over conventional milling cutters are compelling on all fronts The technologies X-NVS [ ] Milling tool with increasing core diameter Improved tool rigidity and less deflection of the tool Superior performance for infeeds ap, ae and the feed rate f Better workpiece accuracy thanks to less tool deflection Smooth transitions The transitions between the shaft, neck and cutting edge have smooth gradients and radii Improved tool rigidity and therefore less radial deflection Minimal stepping when working with multiple infeed depths igher mechanical resistance for better performance Tools with polished teeth Reinforcement of the exposed cutting edge Absorption of higher cutting forces Milling tools with special edge reconditioning Reconditioning of the main cutting edge for greater cutting-edge stability Increased mechanical and thermal loading of the cutting edge Overall lengthening of tool life Tools with an edge designed for machining hardened materials The special, polished edge facilitates penetration operations with angles of up to in all hardened steels Greater flexibility Thanks to their high rigidity, the X-NVS tools are excellent for PC strategies: igh axial and radial infeed rates when machining high-hard materials such as cold work steels and SS are among the strengths of these tools. The Tri-Layer Duro-Si hard coating features extraordinary resistance to abrasive wear. Combined with a very fine-grained hardened metal with outstanding edge strength, this allows the tools to be deployed in demanding DC milling strategies. With these tools, it s possible to obtain not only high material removal rates but also excellent surface qualities.
