Walter has introduced new grades of its 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. The WPP20G is a universal grade ideal for most applications, with an optimized performance between toughness, hardness and tool life. And the heavy duty WPP30G grade is for interrupted cuts and unfavourable machining conditions. Walter now offers these three Tiger·tec Gold grades, designed for turning operations in steel (with cast iron as a secondary application). Walter says that hundreds of customer tests globally have shown the new inserts increase tool life by an average of about 50 percent, thanks largely 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 also minimizes 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. This produces a smooth rake face, reducing friction and also increasing toughness. This boosts process reliability in automated processes.
