The present invention relates to apparatuses and methods for laser treatment, more particularly laser roughening, of surfaces.

Devices for producing roughened surfaces

The invention relates to a method for creating a press connection arrangement and a clamping connection, the method including a plurality of steps, as well as a press connection arrangement and a clamping connection per se.

Method for creating a press connection arrangement, press connection arrangement and method for creating a clamping connection as well as the clamping connection itself and the use thereof

The invention relates to a device for roughening cylinder bores using a beam tool and offering a very high level of process reliability even for a large quantity.

Method and apparatus for laser beam roughening of surfaces of substrates

A honing tool has a tool body and shells disposed on the tool body. Honing stone sets each provided with two or more honing stones are provided. The shells each support one of the honing stone sets. Guide bars of the honing tool are placed against the bore and a portion of the bore is conically honed with decreasing stroke of the honing tool, wherein a lower reversing point of the honing tool remains substantially unchanged. Honing is terminated as soon as an upper reversing point has reached a predetermined terminal value. Alternatively, a portion of the bore is conically honed with a constant stroke of the honing tool, wherein reversing points of the stroke of the honing tool remain substantially unchanged and a feeding force pressing the honing stones against the bore is controlled as a function of a position of the honing tool in the bore.

Method and device for producing non-cylindrical bores with at least one recess by honing

A method for machining a surface of a metal component, in particular a connecting rod or a cam for a motor vehicle, including the following steps: providing a metal component which has a surface to be machined; premachining the surface to be machined; structuring the premachined surface by a laser beam in such a way that elevations but no depressions are formed as laser structures on the premachined surface with respect to the level thereof.

The present invention in one or more embodiments provides a roller tool for roughening a friction ring of a brake disk, the roller tool including a roller body including inner and outer ends and a casing surface positioned therebetween, the inner end differing in cross-section dimension than the outer end, the casing surface including thereupon one or more protrusions for contacting the friction ring. The roller tool may further include a support frame supporting the roller body. The support frame may include a short leg connected to the outer end of the roller body and a long leg connected to the inner end of the roller body.

Roller tool for making a brake disk

A dressing device for dressing honing stones is provided with a base body and a mounting device for mounting the dressing device in a grinding machine. The base body has at least one honing stone receptacle that is a pocket. Honing stones are inserted and secured in the honing stone receptacles and the abrasive coating of the honing stones are ground by the grinding machine. A set of honing stones that is required for furnishing a honing tool can be dressed by one mounting action in the dressing device and can be inserted into the honing tool so as to be positioned exactly at the same radial position without requiring additional machining.

Honing tool as well as device and method for dressing honing stones

A method is proposed for producing a cylinder working surface of an internal combustion engine that is optimized in terms of friction and wear.

Method for producing a coated surface of a tribological system

The present invention in one or more embodiments provides a roller tool for roughening a friction ring of a brake disk, the roller tool including a roller body including inner and outer ends and a casing surface positioned there-between, the inner end differing in cross-section dimension than the outer end, the casing surface including thereupon one or more protrusions for contacting the friction ring. The roller tool may further include a support frame supporting the roller body. The support frame may include a short leg connected to the outer end of the roller body and a long leg connected to the inner end of the roller body.

Method for making a brake disk

The invention relates to a device () for the combined precision turning and honing of a cylindrical borehole (). The device () according to the invention can comprise either only honing stones () which can be fed or also cutters () that can be fed during machining.

Device and method for machining a cylinder bore by means of a geometrically defined cutter and a geometrically undefined cutter

The invention proposes a device which prepared a cylinder bore of a combustion engine in one working stroke such that the cylinder bore can subsequently be thermally coated.

Tool and method for mechanical roughening

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.

The invention relates to a machine for creating non-cylindrical bore surfaces having a machine spindle (), to which a machining tool (--) can be connected, onto which a feed movement is transferred via a feed means (-). A direct axially parallel acting linear drive (-) is provided in the tool fitting unit () associated with the machine spindle () for fine feeding, the feed movement of which overlaps the first mentioned feed movement, and the actuating means (-) of which acts upon a feed (-) that is disposed together with the machining tool (--) and the means for deflection (--) of the feed movement in a tool unit () that can be exchanged on the tool fitting unit ().

Machine for creating non-cylindrical bore surfaces

The invention relates to a method for rough-honing the peripheral surface () of a bore (). According to said method, a honing tool () is introduced into the bore (), the longitudinal axis (M) of the bore () before rough-honing comprising an off-set (s) relative to the finished bore (). Said off-set (s) is evened out during rough-honing.

Method for rough-honing the peripheral surface of a bore

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.
