Walter unveils its new Tiger·Tec® Gold WKP01G and WPP05G grades that are tailored for maximum performance when turning high alloy-high tensile strength steels. The innovative turning inserts reduce machining time from 20 percent to 30 percent.
Walter specially developed the WKP01G for finishing high tensile steel and cast iron (ISO P01 and K01 workpiece groups) at the highest cutting speed. A very hard substrate provides the highest flank wear resistance, while the multiple-stage post-treatment process produces an extremely smooth rake face to significantly reduce friction and improve toughness. A sharp cutting edge with thinner CVD coating provides precise chip breaking for finishing operations.
The WPP05G grade is for medium and rough turning of steels at the maximum cutting speed. The substrate is made of a carbide with the highest hot hardness, making the insert suitable for both dry and wet machining, and highest crater as well as flank wear resistance.
Both grades feature the Tiger·Tec Gold coating technology. The multiple-layer medium-temperature titanium carbo-nitride (MT-TiCN) coating improves the elastic property of the highly aligned crystals, which do not detach from the substrate like a conventional TiCN coating to offer more wear resistance. The coating increases toughness and resistance to the flank face. In addition, the coating on the WPP05G grade has a highly textured aluminum oxide (Al2O3) coating to minimize crater wear. On average, the coating increases tool life by up to 50 percent.
Both WKP01G and WPP05G grades are ideal for continuous cutting and occasional interrupted cuts in high tensile materials (approx. 280-410 HB or 130-200 ksi). Ideal applications include large-scale production of components for the automotive and energy industries, such as gearboxes, gears, and rotor hubs, as well as forged shafts for general mechanical engineering and wheel sets for the rail industry.
Walter offers the new Tiger·Tec Gold WKP01G and WPP05G grades in around 130 inserts with 11 different geometries.
Walter, a global leader in the metalworking industry for more than 100 years, offers a wide range of precision tools for milling, turning, drilling and threading applications.
