    Abstract: An expansion clamping device includes a base body and an expansion socket. The expansion socket is inserted into the base body to form a pressure chamber. The pressure chamber can be applied with a hydraulic medium while elastically deforming the expansion socket, in order to achieve a clamping effect in a receiving space which is open in the axial direction of the base body towards a face side and is surrounded by the expansion socket in the circumferential direction. The expansion socket has an elastically deformable clamping section and a collar projecting outwardly in the radial direction on the face side. The expansion socket bears with a bearing surface of the collar in the axial direction against a contact surface of a contact shoulder of the base body and, at least in the region of the bearing surface, is firmly connected, in particular by a material bond, to the base body. The clamping section transitions into the collar in a transition region, a recess being formed in the expansion socket in the transition region in such a way that the transition region overlaps over the contact shoulder of the base body in regions, the bearing surface of the expansion socket bearing against the contact surface in a radially outer contact region thereof, and the contact surface having a radially inner free region adjacent to the contact region, in which free region the expansion socket does not bear against the contact surface.

    Abstract: A method of making a cutter structure comprising super-hard material defining a rake face topology is provided. The method includes providing a pre-sinter assembly comprising a substrate body having a formation surface defining a topology complementary to the rake face topology, and an aggregation comprising a plurality of super-hard grains, the aggregation disposed adjacent the formation surface of the substrate body, the substrate body comprising a source of catalyst or binder material capable of promoting the sintering of the super-hard grains at a pressure and temperature at which the super-hard material is thermodynamically stable; subjecting the pre-sinter assembly to the pressure and temperature to provide a sintered polycrystalline super-hard structure joined to the formation surface of the substrate body at a first major boundary of the super-hard structure and having a second major boundary surface opposite the formation surface; removing the substrate body to expose the first major boundary of the super-hard structure defining the rake face topology. Cutter inserts and machine tools are also provided.
