Kennametal's New Development of Beyond Tungsten Carbide Inserts

Recently, Kennametal, as the leading tungsten carbide inserts producer, exhibited at the IMTS 2014 show and announced the introduction of a range of new Beyond Drive tungsten carbide inserts specifically designed for cast irons, steels, and stainless steels that make up many critical components over a variety of industries. Like all of Kennametal’s Beyond™ line of products, Beyond Drive inserts feature a proprietary post-coat surface treatment that improves edge toughness, reliability, and depth-of-cut notch resistance, and a micro-polished surface to reduce friction and workpiece sticking (BUE). A fine-grained alumina layer allows for increases in cutting speed, improving productivity and reliability at high cutting temperatures.

With Beyond Drive tungsten carbide inserts, adding a new titanium oxy-carbonitride outer coating (TiOCN) not only increases wear- and abrasion-resistance, its bronze colour is also an effective wear indicator. Depending on the application, field tests are showing anywhere between 30% and 125% more parts per edge.

　　　　　　　　　　

All new Beyond tungsten carbide inserts are CVD (chemical vapour deposition) coated, but whereas conventional CVD coatings are under tensile stress, Beyond tungsten carbide inserts undergo a proprietary post-coat treatment on all surfaces to reduce this stress, which improves coating adhesion and reduces micro-chipping. More uniform and reliable wear of the cutting edge results in improved and more consistent tool life. “Together with the right geometry, we’ve seen big improvements in cutting performance and tool life in both internal and field tests,” stated Manuel Sedan, Senior Product Manager, Turning Products, at Kennametal.
