Video: Milling Inconel 718 with Cermic Inserts
Metal removal rate is high and the cut is dry. See other basic tips for milling with ceramics.
This video from Sandvik Coromant shows ceramic milling in action. The ceramic insert grade seen here, CC6060, is typically used for milling Inconel 718 engine casings (the workpiece seen here is Inconel 718) as well as for milling components for oil drilling equipment. In both cases, the value of milling with ceramic rather than carbide is a higher metal removal rate.
Although machining exotic materials requires adjustments to shop equipment and personnel as well as a lot of planning and carefully chosen methods, the payoff can be worth it. If a shop establishes itself as an expert with one or more of these materials, potential competitors are limited, and therefore, it can lock in a solid customer base.
