Seco Tools has expanded its Duratomic process technology into a separate and optimised grade chain for grooving and parting-off applications with the TGP25 for steels and TGP45 for various materials.
In the Duratomic process, the aluminium oxide (AL2O3) is arranged at the atomic level to adjust the coating to fit specific applications and workpieces.
Both of the new grades also feature tailored substrates.
When compared to previous Seco grades, the TGP grades offer major improvements in durability and versatility.
While TGP25 is developed mainly for machining steel and TGP45 for parting off steel, both are also suited for stable and high-speed applications in stainless steel and as a tough alternative for cast iron.
Features include: good levels of heat resistance resulting in faster feeds and speeds; prolonged and predictable tool life enabling unmanned production; extreme flank wear resistance for accurately machined parts over a long period of time; low risk of edge build-up resulting in superior surface finish; and a wide application window for flexibility and versatility.
TGP25 is being offered in inserts for groove turning to complement Seco's multi-directional turning program.
When compared against Seco's existing solution for this market, TGP25 offers a 10 per cent to 20 per cent increase in cutting speed to improve productivity while maintaining tool life.
TGP45 is available in Seco's 150.10 insert range.
When compared to competitive Seco products, cutting speeds can be increased by 10 per cent to 15 per cent for a gain in both productivity and tool life.
