Machining Graphite - Keys to Success

Fifth, it is a good practice when milling graphite to ''Climb Mill'' or work from the outside into the material. When milling pockets avoid leaving islands when the endmill cuts from the pocket perimeter into the center of a pocket. The island material will break out when the final island is removed resulting in a pockmarked cavity.

How to mill graphite electrode Professional industrial ...

When milling graphite conventionally (non high-speed), most people tend to set both the spindle RPM and the feed rate too low. Get those RPM’s up there – you’ll see the difference! If you want to be a bit cautious, start by increasing the RPM’s by 10%, but remember to increase the feed rate as well.
