Ball Mill Rpm Newbie Questions Apc Forum Aug 15 2012 ball 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 775 inchs wide and 105 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 Milling Speed And Feed Calculator Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth such as an end mill or face mill calculations use the desired tool diameter number of teeth cutting speed and cutting feed which should be chosen based on the specific cutting conditions including the workpiece material and tool material Ball Nose Milling Strategy Guide In The Loupe Jun 26 2017 ball nose milling without a tilt angle ball nose end mills are ideal for machining 3dimensional contour shapes typically found in the mold and die industry the manufacturing of turbine blades and fulfilling general part radius properly employ a ball nose end mill with no tilt angle and gain the optimal tool life and part finish follow the 2step process below see figure 1 Mill Critical Speed Determination Enter the measured mill rotation in revolutions per minute result 1 this mill would need to spin at rpm to be at 100 critical speed result 2 this mills measured rpm is of critical speed calculation backup the formula used for critical speed is n c 766d05
