Abstract (en)
[origin: WO2019076990A2] The present invention relates to a method for producing one or more concave cut-outs (32) on a main body (22) which is, in particular, substantially cylindrical, more particularly for producing one or more grooves (34) on an armature (40), a push rod (72), or a magnetic keeper plate, comprising the following steps: - providing a substantially cylindrical main body (22) having a first axis of rotation (T1), - rotating the cylindrical main body (22), by means of a lathe (24), about the first axis of rotation (T1) in a first rotational direction, and - rotating a striking tool (26), provided with a number of fly cutters (30), about a second axis of rotation (T2) in a second rotational direction opposite to the first direction, said second axis running parallel and offset to the first axis of rotation (T1), so that the fly cutter (30) engages stock-removably with the main body (22) in order to produce the cut-out (32). The invention also relates to an armature, a push rod and a magnetic keeper plate, having one or more cut-outs produced according to this method, and to an electromagnetic actuator comprising an armature of this type or a keeper plate of this type.
