Abstract: One example of the invention relates to an indexable insert comprising a base that has flanks and at least one face. According to one example of the invention, primarily the face(s) of the indexable insert, but not the flanks thereof, are coated with a very thick layer (e.g. thicker than 50 ?m) of a hard material in a PVD process.

Abstract: An electromagnetic linear actuator has a frame (stator) and an armature each at least partially formed of soft magnetic material. The armature can be moved relative to the frame along a longitudinal axis, they form a gap therebetween in an open position and lie against each other in a closed position with the gap closed. A first armature coil is connected to the armature so that a force acting on the first armature coil is transferred to the armature. An excitation magnetic field is generated and guided at least partially by the frame and the armature and acts with a force on the first armature coil when current flows through the first armature coil, to close the gap. The frame, the armature, and the excitation magnetic field are configured so that a retaining force takes effect when the gap between the frame and the armature is closed.

Abstract: Method for the production of indexable inserts, which exhibits the following: Deposition of a layer of cutting tip material forming the indexable inserts (40) by means of a PVD method on a dissolvable profiled substrate (10), and—dissolving of the substrate to produce the form of free-standing parts as indexable inserts.
