determine the spindle speed (rpm) and feed rate (ipm) for a milling operation as well as the cut time for a given cut length. milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth such as an end mill or face mill.
i've used the first of these mills that i got with the original drive belt for many many hours of milling with only a little oiling of the bushings. standard length mill times are half an hour for individual chemicals and 2 4 hours for high quality black powder. 6 pound dual drum ball mill

optimizing the ball mill's rpm make sure the whole roller assembly now looks as it originally did and rotates freely. there you go a larger 3/4inch diameter drive roller simple as that. testrun the mill with a jar on it and verify that the speed of the jar's rotation has increased to approximately 8090 rpm.
a ball mill grinds material by rotating a cylinder with steel grinding balls causing the balls to fall back into the cylinder and onto the material to be ground. the rotation is usually between 4 to 20 revolutions per minute depending upon the diameter of the mill. the larger the diameter the slower the rotation.
when making finish passes you would reduce this number to 10% especially when using a 1/16 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 hf 500 spindle then this number would control the rpm. if you are using a dremel or a router such as
end mills (endmills) are used in a milling machine to remove stock amp shape work pieces in a wide range of materials in both high volume production and maintenance and repair applications. choose from a wide range of styles including finishing roughing ball corner rounding and more.
