# how i calculate the optimam speed of a ball mill

The Ball Mill Finish Calculator can be used when an end mill with a full radius (a ball mill) is used on a contoured surface. The tool radius on each side of the cut will leave stock referred to as a scallop. The finish of the part will be determined by the height of the scallop amd the scallop will be determined by the stepover distance
