Seco developed the new TM4000 grade for its single-point threading inserts to provide the highest possible protection against built-up edge when turning steel workpiece materials. A first of its kind, the grade features a hard, ductile cemented carbide substrate and special dual coating made of CVD and Duratomic layers.
\nThe grade\u2019s first CVD Ti (C, N) layer and second Al2O3 Duratomic layer together create a coating that provides superior wear resistance at high cutting speeds and prevents built-up edge in low-speed threading applications. As a result, inserts that feature this grade achieve optimum tool life and up to 15 percent faster thread cutting speeds as compared with the company\u2019s previous threading line.
\nExclusive to Seco, Duratomic technology arranges aluminium and oxygen atoms in a unique way to produce a durable coating that provides high toughness and abrasion resistance.
\nThe insert\u2019s cemented carbide substrate also adds value by delivering a balance between hardness and ductility to successfully tackle high-heat applications and withstand thermal and mechanical shocks.
\nAble to perform equally well on high and low-power machine tools, TM4000 threading inserts feature precision-ground profiles that can effectively handle both I.D. and O.D. operations. Available in Seco\u2019s Snap-Tap\u00ae insert design, they can also produce a wide variety of thread profiles, including ISO, Unified, Whitworth, BSPT, NPT, Round thread, Trapeze thread ACME, Stub ACME, API and API round.<\/p>\n","protected":false},"excerpt":{"rendered":"
