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.
Though it won’t replace high speed machining, Boeing sees “low speed machining” as a viable supplement to higher-rpm machines. Using new tools and techniques, a shop’s lower-rpm machining centers can realize much more of their potential productivity in milling aluminum aircraft parts.
Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly reduce the number of requisite test grinds.
By using specialized cutter geometry and incorporating smooth finishes with tough coatings, Toolmex Corp., created an end mill well suited to cut aluminum aggressively. This tool called the "Mako" is part of the SharC line of specialized tools from the same company.
