Introduction to Inserts
Inserts are replaceable cutting tips used in machining operations. They are designed to be mounted on cutting tools such as milling cutters, turning tools, and drills. Inserts are made from various materials, including carbide, ceramic, and cubic boron nitride (CBN), each with unique properties suitable for different machining applications. They offer several advantages over traditional solid cutting tools, such as cost – effectiveness, as only the worn insert needs to be replaced, and improved machining efficiency due to their optimized geometries.
