Abstract: A facade panel screw for the optimized fastening of facade panel elements to a substructure has a head having a very large diameter, a subsequent, essentially cylindrical shaft section (22) extending along a central longitudinal axis (A) and a subsequent tip region (23). The shaft section (22) includes, as viewed from the head, a threadless underhead section (24), a stop collar (25) and a threaded section (28). The thread in a first part (26) of the threaded section (28) subsequent to the stop collar (25) has an outer diameter Dr, which is attenuated compared to the thread in a second part (27) with outer diameter Dn, over several convolutions, so that Dr<Dn. This threaded section 26 allows a controlled overwinding of the facade panel screw in use. A corresponding fastening arrangement includes a facade panel, a substructure for transferring the load to a building surface and the facade panel screw.

Abstract: A method for establishing a connection, with the following steps: inserting a sleeve (12) having a stop flange (10) into a bore (14), in such a way that the stop flange (10) is at a distance from a bore edge (16); anchoring at least one elevation (18) of a free end portion (20) of the sleeve (12) in the bore wall (22) by widening the free end portion (20) of the sleeve (12); and moving the stop flange (10) in the direction of the at least one fixed anchored elevation (18) of the free end portion (20) of the sleeve (12), by widening a further portion (24) of the sleeve.

Abstract: In the case of a honing method for machining the internal face (214) of a bore (210) in a workpiece (200) with the aid of at least one honing operation, during a honing operation a flaring-capable honing tool (150) that is coupled to a spindle is moved back and forth within the bore for generating a reciprocating movement in the axial direction of the bore, and are simultaneously rotated for generating a rotating movement that superimposes the reciprocating movement. A bore shape having an axial contour profile which is rotationally symmetrical in terms of a bore axis (212) and deviates from the circular cylindrical shape is generated herein. For generating an axially variable material removal in at least one stroke modification phase a stroke length and/or a stroke orientation of the reciprocating movement is modified.

Abstract: A honing method for machining the inner surface of a bore in a workpiece via at least one honing operation using an expandable honing tool with an annular cutting group. The method includes coupling of the honing tool to a working spindle of a machine tool, and; inserting the honing tool into an inlet of the bore with the cutting material elements retracted, until it is in a final insertion position, in which the cutting group is located in an end region of the bore. Then the honing tool is turned and the annular cutting group is simultaneously expanded to create a cylindrical widening of the bore, followed by withdrawal of the honing tool from the bore with simultaneous turning of the honing tool in such a way that the bore is successively further widened in the direction of the inlet side.

Abstract: In a honing method for machining the internal surface of a bore in a workpiece with the aid of at least one honing operation, during a honing operation, an expandable honing tool is moved up and down within the bore in order to produce a reciprocating movement in the axial direction of the bore and at the same time is rotated in order to produce a rotational movement combined with the reciprocating movement. In the process, a bottle-shaped bore is produced, said bore having, following a bore inlet, a first bore section with a first diameter, a second bore section with a second diameter, which is larger than the first diameter, away from the bore inlet, and a transition section with a continuous transition from the first to the second diameter between the first and the second bore section.
