Milling different materials - Sandvik Coromant
Preferably, use 65/60/45 degree cutters; If cutting fluid must be used to avoid dust, etc. choose wet milling grades; Coated carbide is always the First choice, but ceramics can also be used. Note that the cutting speed, v c, should be very high, 800–1000 m/min (2624–3281 ft/min). Burr formation on the workpiece limits the cutting speed.
