Reliable solution for heavy-duty applications

With its indexable inserts featuring the new CBN grade WBH20C, Walter is for the first time launching a cutting tool material developed in-house.

The tools are available as full-radius and V-shaped inserts with Walter Lock positive engagement, either with or without wiper geometry for ISO inserts. The CBN indexable inserts with the newly developed HiPIMS coating are the only one of their kind on the market. Patents are pending for the coating (TiAlN PVD with a zirconium nitride top coat), the layer bonding to the CBN and the pre-machining process.

When used with the Walter Lock positive engagement, which was also developed in-house at Walter, the indexable inserts offer exceptional stability in the insert seat. This reduces micro-fractures at the cutting edge and ensures longer tool life and improved process reliability, making the inserts perfect for profile turning and dynamic turning.

The CBN turning inserts are suitable for finishing hardened steels, including operations involving interrupted cuts. They are suitable, and recommended, for use with coolant. This replaces grinding in many cases. Alongside the increased process reliability, the wear resistance of the new grade is particularly appealing to users. This is the result of the combination of ultra pure CBN and a new type of PVD coating with excellent layer bonding. A light top coat optimises wear detection. Potential areas of use are ISO H materials up to 65 HRC, such as heat treatable steels or bearing steel.
