RPMs on a ball mill and a star rolling machine. Okay, im quotconsideringquot building a combo machine for ball milling and star rolling the thing im confused about is the rpm of the drums i always thought a ball mill should be fairly slow because rock tumblers that ive seen are fairly slow maybe revs per minute i guess im wrong ive seen recommendations of much higher speeds of

Feb 25, 2010· On the same job I used a 0.750" 3 insert cutter to hog out some pockets. It just purred right through it as well. It hammered quite a bit more than the big face mill and had an even more machine-gun effect. I think I ran at the recommended F/S of 4020 RPM at 71 IPM 0.200 DOC and 0.175 WOC. I'm a firm (and happy) believer in carbide.
