When making finish passes, you would reduce this number to 10, especially when using a 116 ball nose end mill for detail carving. it will give you the best finish results. feeds and speeds. spindle speed if you are using a stepcraft hf500 spindle, then this number would control the rpm. if you are using a dremel or a router such as ...
Aug 15, 2012nbsp018332ball mill rpm posted in newbie questions ok so i know this is a question i should be able to figure out on my own i thought i know of some web sites that had the equation but i must have been wrong any way the jar is 7.75 inchs wide and 10.5 inchs long and im using 50 cal round musket balls for media it will be half full of media so what rpm should i run it at thanks so much
For example, using a 2flute, .250quot ball end mill at 980 sfm with a .002quot ipt chip load, and a .020quot doc axial and radial when the endmill is parallel to the surface cutting with the side, i get a 15,000 rpm spindle speed, and 111 ipm feed rate.

Optimizing the ball mills rpm make sure the whole roller assembly now looks as it originally did, and rotates freely. there you go a larger, 34inch diameter drive roller, simple as that. testrun the mill with a jar on it, and verify that the speed of the jars rotation has increased to approximately 8090 rpm.

Ball milling is one of the few unit operation that improves with increasing mill diameter. if acceptable results can be obtained with a 12 jar mil, then good result will certainly be obtained with a 72 diameter mill. of course there is the possibility of over milling, obtaining a different particle size distribution or a need to change ...
