Tools for turning challenging materials

Troy, Michigan – Seco has increased the application range of its wear-resistant TH1000 and TH1500 turning insert grades by adding new positive and negative geometries, chip breakers, and nose radius sizes to the line. The additions allow manufacturers that process hardened steels, superalloys, and cast irons to further increase their machining capabilities.

 

With its reliable edge toughness and high chip resistance qualities available across a broader product range, the TH1000 TiSiN-TiAlN nanolaminate PVD-coated grade enables manufacturers to productively tackle a wider variety of ISO H5-H10 applications as well as maintain long tool life when machining hardened steels, from 50HRC to 62HRC, hard surfaced components, and superalloy materials.

 

TH1000 excels in finishing operations and performing interrupted cuts in hardened steels. With respect to machining superalloys, such as Inconel 718, Waspaloy, and Nimonic C263, the grade brings fast cutting speeds to continuous finishing and semi-finishing operations. Furthermore, the latest TH1000 chipbreaker inserts bring optimum chip control and high process security to a broader working range.

 

For processing hardened steels, from 40HRC to 55HRC, the Duratomic TH1500 grade, through its product expansion, allows manufacturers to excel in an increased number of ISO H10-H15 applications that require high cutting data and continuous-cut operations. TH1500 also provides superior finish turning of grey and ductile cast irons in applications with low-to-moderate cutting speeds.

 

Because of its advanced grade profile, which includes an α-based Al₂O₃ CVD coating, Ti (C,N) middle layer, and a super fine grain substrate, TH1500 is an alternative to CBN and ceramic cutting tools in situations that involve machining hardened steel workpieces in unstable conditions.

 

The additions to the TH1000 and TH1500 product lines increase the number of turning solutions available to parts manufacturers serving the aerospace, automotive, and energy industry segments. The additions also allow the company to provide total solutions for machining challenging materials. TH1000, for example, complements the TS2000 and CP200 carbide grades and CBN170 grade to form a complete finish machining package for superalloy materials. TH1500, because of its superior finishing turning capabilities in grey and ductile cast iron, nicely complements the company’s TK1001 and TK2001 grades.
