Milling different materials - Sandvik Coromant

Ceramic milling typically runs at 20 to 30 times the speed of carbide, although at lower feed rates (~0.1 mm/z (0.0039 in/z)), which results in high productivity gains. Due to intermittent cutting, it is a much cooler operation than turning. For this reason, speeds of 700–1,000 m/min (2,297–3,280 ft/min) are adopted for milling
