Even though Tiger-tech Gold has only been available as part of Walter's standard range since the beginning of 2017, the new coating technology for indexable inserts has already taken the market by storm, as the manufacturers report. The key to its success is the new type of coating on the indexable inserts used for milling, which features a highly wear-resistant TiAlN layer. This is applied using a low-pressure process (ULP/CVD) that has been developed in-house and reportedly minimizes typical manifestations of wear such as abrasion, deformation, hairline cracks and oxidation. As the exhibitors point out, their new indexable insert types and geometries in the milling grade WKP35G extend the range of applications to copy milling, slot milling, high-feed milling and slotting cutters. As is claimed, many users from the automotive, mold and die making and energy industries have confirmed the findings of pre-launch laboratory tests. These results apparently show an improvement of cutting parameters and tool life, with some reports even professing increases of several hundred percent.
New additions to indexable insert range
Walter is expanding its Tiger-tec Gold program with the new indexable insert plate types and geometries of the WKP35G milling grade. Qualities such as the excellent balance between wear resistance and toughness and the wide range of materials from gray cast iron, ductile graphite iron and structural steel to high-tensile and stainless steels are said to make the new types a real asset in machining.
