Face milling Coromant
This type of machining is called HighSpeed Machining (HSM). In milling shortchipping materials, such as gray cast iron, a face milling cutter with an extraclose pitch can be used, resulting in high table feed. In HRSA materials where cutting speed is normally low, an extraclose pitch results in a high table feed.
