HIGH SPEED TURNING OF STEEL DUCTILE CAST IRON COMPACTED GRAPHITE IRON

Grade TP1500 is designed for the highest productivity possible, combined with long and reliable tool life at higher speeds and feed rates.

Grade TP1500 from Seco Tools Inc. (Troy, MI) is the newest addition to its line of coated grades produced using the Duratomic process. The grade is designed to be the first choice when customers are aiming for the highest productivity possible in addition to offering long and reliable tool life at higher speeds and feed rates.

TP1500 meets the mechanical and physical demands required for turning steels at very high cutting speeds without sacrificing the toughness needed for reliability. TP1500, in conjunction with the new MR6 chipbreaker, has proven to have longer tool life, increased productivity and lower costs than competitive grades positioned to handle similar applications.

TP1500 was developed using Seco’s revolutionary Duratomic process, where the crystalline structure is manipulated at the atomic level to produce a very durable coating. This process results in the ability to produce a coating with excellent edge toughness in combination with exceptional wear-resistance. While targeted specifically for steel machining, the coating and substrate properties also make TP1500 a good choice for a wide range of cast iron applications, especially those involving ductile and compacted graphite iron.

TP1500 is offered in a very wide range of insert geometries to cover turning applications from finishing to heavy roughing where productivity and/or long tool life are of major importance. The wide application range of grade TP1500, particularly when combined with the new general purpose MR6 chip groove, is an ideal complement to grade TP2500, the first grade to feature this revolutionary Duratomic coating technology.
