AC9115T & AC9125T

Sumitomo has developed and launched new coated carbide grades AC9115T and AC9125T. Each grade has excellent wear resistance and are optimal for turning titanium alloys, with AC9115T for general purpose machining and AC9125T for interrupted machining. Titanium alloy machining has long been subjected to short tool life due to adhesion caused by chemical reactions with the cutting tool, and wear during machining caused by low thermal conductivity.

Titanium alloys are widely used in the aircraft industry due to their light weight, high strength and excellent corrosion resistance. Their applications are also increasing in the medical industry due to its high biocompatibility. In recent years, these industries have been growing rapidly, leading to a yearly increase in the demand for tools able to machine titanium alloys.

Featuring our proprietary PVD Absotech® coating technology in AC9115T and AC9125T, as well as the industry’s first tungsten carbide (WC) based composition that suppresses chemical reactions with titanium alloys and significantly increases wear resistance. The results have shown up to 75% reduction in friction coefficient. This achieves long tool life in turning of titanium alloys, significantly contributing to improved productivity and reduced costs. PVD (Physical Vapor Deposition) is a method of depositing a thin physical coating on the surface of the target material in the vapor phase.

Sumitomo takes pride in being a leader in the development of new technologies in turning and is happy to release the new AC9115T and AC9125T titanium turning grades. We are excited to help provide additional solutions to our customers! See more on the AC9100T  main page: https://sumicarbide.com/product/ac9100t/
