Walter USA offers a series of insert geometries designed to improve productivity in difficult turning applications. The Walter NMS and NRS geometries are well-suited for high-temperature alloys such as Inconel 718 and Waspaloy used in aerospace applications. The NMS geometry is designed for semi-finishing and medium machining in these alloys, but can also be used on ISO M materials including 304/316 austenitic stainless steels. The NRS geometry is suitable for roughing high-temperature alloys as well as the machining of forged and cast surfaces. The inserts’ WSM10 or WSM20 coatings and cutting edge geometry resist formation of notches and cutting edge build-up while decreasing heat generation for extended tool life.
The company also offers the NFT geometry featuring a fully ground periphery for high accuracy in finishing titanium alloys; the NRR geometry providing cut depths ranging to 0.700" (18 mm) for heavy roughing of forged materials; and the RP5 geometry featuring a stable, positive 3-degree chamfer for roughing with low power requirements.
