The Walter Tiger·tec Gold WPP35G milling grade indexable inserts can be used for all standard milling cutters from the company’s range, such as Xtra·tec XT, Walter BLAXX, and M4000. The grade specializes in milling steel and is also excellent for milling cast iron at moderate to high cutting speeds (ISO P and K material groups). The grade is comprised of a carbide substrate with a high level of toughness, topped with a bonding layer to adhere the (MT-TiCN) base layer. A second bonding layer adheres the highly textured (Al2O3) layer which serves as a wear-resistant heat shield followed by a gold-colored (TiN) top layer for wear detection. The highly textured MT-TiCN Tiger·tec Gold coating provides a high level of wear resistance because of the optimized elastic properties of the aligned crystals. In contrast, a conventional TiCN coating wears more quickly because individual crystals detach from the compound. For example, in an application milling a steel C45R component with a hardness of 220HB, a WPP35G insert produced 1,300 components versus 1,000 for an existing grade insert, a 30% increase. The multiple-stage post-treatment process creates a smooth rake face for improved toughness and reduced friction. The milling grade is ideal for short runs and is equally impressive when used in mass production applications. Areas of use include general mechanical engineering, mold and die making, and the aerospace, energy, and automotive industries. The grade is suitable for dry machining, especially steel, or with cooling lubricant. The Tiger·tec Gold WPP35G milling grade is an economical solution when measured on a cost per part, cost per insert or even a cost per cutting edge criteria.
