Proposed in a milling head, which has a plurality of machining milling teeth and tooth gaps arranged therebetween, whereby the milling teeth and the tooth gaps are arranged along a circumferential surface of the milling head, which milling head is to be provided with a number of milling teeth, which is greater than and/or substantially equal to the number of milling teeth ascertained using the equation y=a·x5+b·x4+c·x3+d·x2+e·x+f, wherein x is the diameter of the milling head in millimeters and y is the tooth pitch, i.e. the distance between two adjacent milling teeth in millimeters, and it substantially applies that the value of a ranges between a=1.7·10−9 and a=2.3·10−9, the value of b between b=−5·10−7 and b=−11·10−7, the value of c between c=0.7·10−4 and c=1.3·10−4, the value of d between d=8.5·10−3 and d=9.7·10−3, the value of e between e=2.6·10−1 and e=3.7·10−1 and the value of f between f=−1.5·10−1 and f=−2.6·10−1.
A form cutter milling head with a plurality of machining milling teeth and tooth gaps arranged there-between, which are arranged along a circumferential surface of the form cutter milling head, wherein an actual number of said milling teeth is greater than or equal to a calculated number of milling teeth ascertained from the relationship n=C/y wherein n is the number of milling teeth, y is a tooth pitch of the form cutter milling head defined as a distance in millimeters between two said milling teeth situated adjacent to one another, and C is a circumference in millimeters of the form cutter milling head, wherein the tooth pitch relates to a diameter of the form cutter milling head via a fifth-order polynomial of the form y=a·x5+b·x4+c·x3+d·x2+e·x+f, wherein x is the diameter of the milling head in millimeters, y is the aforesaid tooth pitch in millimeters, and a, b, c, d, e, and f are coefficients of the fifth-order polynomial.
