Where dbmax is the maximum size of the feed mm is the compression strength mpa e is the modulus of elasticity mpa b is the density of material of balls kgm 3 and d is the inner diameter of the mill body m generally a maximum allowed ball size is situated in the range from d 18 to d 24
Ball mill finish calculator 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 between cuts
