摘要:
A brush-honing machine including a brush-honing tool which is displaceable both axially and rotationally thereby displacing a plurality of brush elements of the tool both axially and radially. A step motor is provided the angular movement of which is translated into the noted axial and radial displacement.
摘要:
A method for removing the overspray of a coating which has been sprayed onto a workpiece directs at least one liquid jet from a jet lance as a hydrodynamic wedge in the parting plane between the workpiece and the overspray onto those regions of the workpiece which have overspray.
摘要:
A method of preparing the surface of a substrate (3) for applying a thermal spray coating (2), wherein recesses are introduced in the surface to be coated, which are subsequently shaped such that the created structures have undercuts. A web (4) having a flat plateau surface (4-1) is created by machining, which, starting at the center (5) of the plateau surface (4-1), is shaped into a widened region (6) such that roof-shaped projections (6′, 6″) directed opposite one another on both sides are created, which form undercuts (10) with the sides thereof facing the surface (3-1) of the substrate (3).
摘要:
In a method for machining bores of workpieces with a desired nominal shape of the bores in operative condition, a bore with a desired nominal shape in inoperative condition is produced in a workpiece and the workpiece is then put in operative condition. A deviation of the desired nominal shape of the bore resulting from the operative conditions is determined. Based on the deviation, an initial shape which shape the bore must have in inoperative condition in order for the bore to assume the desired nominal shape in operative condition is the determined. Bores are then produced by employing the determined initial shape as a template.
摘要:
A honing or grinding tool and a measuring device used therewith is descri The honing tool includes a cutting element, a cutting element support and a layer disposed between and connecting the cutting element and the cutting element support. The layer includes a substance embedded therein which selectively absorbs and/or emits electromagnetic radiation at specific wavelengths, such that the substance is exposed when the cutting element is worn off and detected by the measuring device.

摘要:
A workpiece has a tribologically useable surface formed as a sliding surface, lubricated by an intermediate material, for a counterpart movable relative to the workpiece in a direction of movement. The sliding surface is provided with a structure formed of a plurality of pockets. The pockets form a closed micropressure chamber delimited by the uninterrupted peripheral rim, respectively. The uninterrupted peripheral rim is a deburred structure edge. In a plan view, the pockets are elongate and have a longitudinal extension. The sliding surface has a functional roughness in the supporting areas between the pockets.
