Widia, a Kennametal brand, has developed a new milling grade, WS40PM, for use with titanium and other superalloys.

WS40PM has been designed to meet the needs of the aerospace, defense, and medical industries. In tests with a variety of different applications, an aircraft manufacturer experienced a 90% reduction in machining time per piece and increased tool life by 50% during Ti-6Al-4V face milling operations, while for a turbocharger producer in China, tool life increased 80% while machining an austenitic stainless steel component using WS40PM, with improved part surface quality, reduced cutting forces and better chip flow.

‘WS40PM’s advanced cobalt-rich substrate provides robust fatigue resistance and edge integrity, while the multiphase AlTiN-TiN PVD coating reduces wear,’ says Mike Sperhake, EMEA-region product specialist for WIDIA. ‘Using an initial cutting speed of 175 ft/min (53 m/min) we’re seeing 25-35% productivity gains and consistent improvement in tool life, even when milling very tough materials like Ti-5553 and super duplex steels.’
