ABSTRACT:
In order to so improve a machining method for severing a machine part having a bearing eye into a first and a second bearing bushing, wherein the machine part with the bearing eye is mounted on a mandrel comprised of two halves and the halves are moved apart to sever the machine part and wherein prior to and during the severing, the first bearing bushing is fixed in the severing direction by at least one first transverse fixing element, the first bearing bushing is fixed transversely to the severing direction by two first side fixing elements and the second bearing bushing is fixed in the severing direction by at least one second transverse fixing element, that the joining following the severing can be carried out in as simple a manner as possible, it is proposed that prior to the severing, the first and second side fixing elements be positioned in an essentially tension-free manner in the advancing direction against the machine part and be held in this position resting essentially tension-free in the advancing direction against further movement in the direction opposite to the advancing direction during the severing.
