TH1000 - Hardened material and Inconel's most cost-effective shelf grade
TH1000 is a high-tech carbide lathe grade specialized in solutions commonly called difficult materials, such as hardened materials such as heat-treated steels with HRc 50~62 and heat-resistant alloys such as Inconel.In the automotive and aerospace industries, it is generally accepted that carbide inserts melt at 600~800°C, making it impossible to process hardened materials and difficult materials at high speeds. Saeco Tools' TH1000 lathe grade is abrasion resistant that can withstand 1.5~2 times the speed of conventional finishing grades. Other tool manufacturers offer solutions that deliver similar performance, but they only last half the life of their tools compared to Seco Tools.
TH1000 is a high-tech carbide lathe grade specialized in solutions commonly called difficult materials, such as hardened materials such as heat-treated steels with HRc 50~62 and heat-resistant alloys such as Inconel.
It is a TiSiN-TiAlN Nanolaminate PVD coating grade, with a nanolaminated PVD top layer for maximum toughness and high chipping resistance. It is also highly resilient to edge cracks that occur during machining of hard surface parts and lathe finishing of hardened steel parts. Therefore, it boasts unrivaled performance in high-hardness materials and Inconel.
If you have been using PCBN and ceramic inserts in the past, the TH1000 grade can benefit greatly in terms of machining productivity and cost-effectiveness. Chip control issues, especially with CBN inserts and ceramic inserts, can be solved with the TH1000 with chipbreaker.
In addition, solid CBN and ceramic inserts have very low raw material regeneration efficiency and are usually discarded after use. With its easy recycling of raw materials, TH1000 carbide inserts not only significantly reduce tool costs, but also contribute to environmental protection.
The first recommended chipbreakers for TH1000 are:
- -MF1, -MF2 : Finishing of hardened steels and Inconel
- -MF5: Heavy finishing of high hardness steel
- -M3, -M5: Medium Cutting of High Hardness Steel
If you enter [Cutting Data] on the insert search screen on the SECO website, you can check the exact recommended cutting conditions according to the change in hardness.
