The core challenge to grinding a perfect ball is maintaining a precise radius from the tip of the nose back to the shank of the tool. To achieve this, a relief must be ground into the end of the tool, that leads out to an intersection of the outside diameter so that when it gets to the tangent point, creates a perfect radius.
