- the predetermined breaking points 2 are unevenly spaced apart to achieve uniform splinters.
- a lienförmigen predetermined breaking point 2 along the circumference U is generated by the fixed heat source 5 acts selectively on the projectile casing 1, while this rotates about the longitudinal axis L by 360 °.
- the receiving device 6 is moved by a value corresponding to the distance of the two predetermined breaking points 2.
- the distance of the predetermined breaking points is adapted to the wall thickness W of the projectile casing 1.
- the projectile casing 1 is moved over its entire length with respect to the heat source 5 by the receiving device 6.
- a distance between the predetermined breaking points 2 running parallel to the longitudinal axis L can be achieved by rotating the projectile casing 1 in each case after the production of a predetermined breaking point 2 running along the longitudinal axis L by a predetermined angle. In this way, along the route U generated equally spaced predetermined breaking points 2, which extend along the longitudinal axis L. Since the wall thickness W of the projectile casing 1 is uniform along the circumference U, the distances between the predetermined breaking points 2 along the circumference are also uniform.
- the predetermined breaking points 2 extending in the longitudinal direction L and along the circumference are formed as material structure changes which extend over the entire wall thickness W of the projectile casing 1.
- the predetermined breaking points 2 to achieve uniform splinters are unevenly spaced from each other. In this way, the number of chips whose mass is in a desired range can be increased. At the same time, the number of slivers that are too heavy and / or too light can be reduced. Thus, an improved fragmentation with an increased number of effective splinters can be made possible.
