Walter AG, a leading player in the international metalworking industry, is launching two innovative high-performance cutting tool materials for turning operations in the form of the WKP01G and WPP05G grades, which reduce the machining time by between 20 and 30 percent. WKP01G has been specially developed for finishing high-tensile steels and cast iron (GGG/GG) at the maximum cutting speed and is the only one of its kind on the market designed specifically for this purpose. The optimized cutting edge rounding of the turning inserts improves the surface quality of the workpiece, while their multi-stage post-treatment produces an extremely smooth rake face, which significantly reduces friction. The WPP05G grade is designed for medium machining and roughing of steels at the maximum cutting speed. Both cutting tool materials are ideal for finish cuts and occasional interrupted cuts in high tensile materials (900–1400 N/mm²).
The main USP of the inserts is their coating with the patented Tiger·tec® Gold technology. This fine-columnar, highly textured MT-TiCN multi-layer coating increases toughness and resistance to flank face and crater wear. As a result, the grades make it possible to increase the machining speed and the associated productivity by between 20 and 30 percent compared to standard ISO P10 grades. The company offers the new grades in around 130 versions with 11 different geometries. Application ranges include high-volume and mass production in the automotive or energy industries (for example, gearbox components, gears, and rotor hubs), general mechanical engineering (for example, forged shafts), or the rail industry (for example, wheel sets).
