Walter USA introduces new grades of Tiger·tec Gold inserts for turning steel with a variety of both negative and positive geometries. The WPP10G grade is primarily for continuous cuts and highest cutting speeds. According to the company, the WPP20G is a universal grade ideal for most applications, with an optimized performance between toughness, hardness and tool life. The tough WPP30G grade is for interrupted cuts and unfavorable machining conditions. Walter now offers three Tiger·tec Gold grades specifically designed for turning operations in steel (with cast iron as a secondary application). In hundreds of customer tests globally these new inserts have reportedly increased tool life by an average of approximately 50%, which Walter says is largely due to their layered structure of coatings.
A patent-pending, highly textured, multi-layered MT-TiCN layer increases toughness and reduces flank face wear, resulting in lower cost per cutting edge. The inserts’ highly textured Al2O3 layer is said to minimize crater wear, and the gold-colored top layer improves wear detection. The gradient carbide substrate boosts wear resistance and toughness. In addition, Walter provides its signature multi-stage post-treatment, which produces a smooth rake face that is said to reduce friction and increase toughness, ensuring high process reliability in automated processes. With this expansion of the product range, Walter says users can now benefit from maximum flexibility and minimal component costs when turning.
