Publication number: 20220143713Abstract: Cutting insert for a tool for machining. The cutting insert is particularly suitable for grooving tools for grooving turning. The cutting insert has a chip breaker geometry in its cutting region, which enables both machining of full cuts and machining of partial cuts as well as machining of webs. In particular, due to the shape of a chip cavity provided in the cutting region and due to the presence of a negative chamfer, very short chips can be produced in all three machining variants, so that a high level of process reliability is ensured and long tool lives are made possible.Type: ApplicationFiled: January 26, 2022Publication date: May 12, 2022Inventors: Marc STEINHILBER, Hans SCHÄFER
