摘要:
Die vorliegende Erfindung betrifft eine Schleifvorrichtung (1) zum vorzugsweise ebenen Schleifen und/oder Polieren eines Flansches mit einem vorstehenden Teil, wie Achse, Welle oder Gewindebolzen, wie beispielsweise einer Kraftfahrzeugnabe, mit einem Gehäuse (7), das einen hinteren Drehabschnitt (8) für eine Rotation des Gehäuses (7) um eine Rotationsachse (20), einen um die Rotationsachse (20) angeordneten vorderen Ausnehmungsabschnitt (15) für eine Aufnahme des vorstehenden Teils und einen konzentrisch zum Ausnehmungsabschnitt (15) angeordneten Befestigungsabschnitt (17) für eine Befestigung eines Schleifkörpers aufweist, wobei der Befestigungsabschnitt (17) eine Verdrehsicherung zum Befestigen des Schleifkörpers an dem Gehäuse (7) aufweist.
摘要:
A rotatable disc head for a floor treatment device comprises a pair of coupling members which are pivotably connected to each other according to pivot axes which are transversely oriented with respect to each other. A rotation axis is defined which is transversely oriented with respect to said pivot axes. The coupling members are furthermore connected to each other by means of at least an elastically deformable connection element. One of the coupling members comprises fitting means for mounting said coupling member to the rotary drive of the floor treatment device and the other coupling member comprises carrier means onto which a floor treatment element, such as a grinding disc, can be mounted. The connection of the connection elements to one of the coupling members is an adjustable connection allowing displacements which are oriented transversely with respect to the rotation axis.

An abrasive article comprises a porous abrasive member (104), a nonwoven filter medium (120), a second nonwoven filter medium (140), and optionally a porous attachment layer (146). A plurality of openings in the porous abrasive member cooperates with the first nonwoven filter medium to allow the flow of particles from an outer abrasive surface of the porous abrasive member to the second nonwoven filter medium. Methods of making and using the abrasive articles are included.

The invention provides an electric hand-held machine tool for carrying out grinding work, in particular an orbital sander, which has a drive plate (16), which can be driven by an electric motor to perform the grinding movement, and a grinding plate (21'), which can be detachably fastened to the said drive plate without using a tool and has means for fixing a sanding sheet (22'). To create a multifunctional device, with which different kinds of grinding work can be optimally carried out, a well-like depression (23) has been made in the upper side of the grinding plate (21'), facing the drive plate (16), with a planar well base (231) for receiving the drive plate (16) with interlocking engagement, and the detachable fastening of the grinding plate (21') without using a tool, preferably by Velcro attachment, is performed between the well base (231) and the face of the drive plate (16). Easy exchange of the grinding plate makes it possible for grinding plates (21) of different configurations to be changed quickly to suit different grinding work requirements.

An unpolished work holding board having a high-precision work holding surface obtained by improving materials for the holding board body of an unpolished work holding board which vacuum-sucks/holds a work and for a resin coating spread on a work holding surface, and by developing a resin coating method which does not close with resin through holes in the holding board body; and a production method thereof. An unpolished work holding board provided with a work holding board body having many through holes for vacuum-sucking/holding a work, wherein the holding surface of the holding board body is covered with a coating formed by heat-curing a thermosetting resin spread on the holding surface and the surface of the coating is polished; and a production method thereof.

Die Erfindung betrifft eine Werkzeugmaschine (10), insbesondere Schleifmaschine, umfassend eine Antriebseinheit zum Antrieb eines verbindbaren Werkzeugs (36), eine Werkzeugeinheit (12) aufweisend eine Werkzeugaufnahme (34b), an der das verbindbare Werkzeug (36) angebracht werden kann, sowie eine haubenförmige Staubschutzabdeckung (14) im Bereich der Werkzeugaufnahme (34b), wobei die Werkzeugeinheit (12) mittels einer Tragestruktur (20) an der Werkzeugmaschine angebracht ist, sowie eine Luftführung, die sich zur Abführung von Absaugluft und darin enthaltenen Staubpartikeln von der Staubschutzabdeckung (14) bis hin zu einer Absaugeinrichtung erstreckt. Die Luftführung (40, 42, 44, 46) ist erfindungsgemäß vollständig in die Tragestruktur (20) integriert.
摘要:
The present invention describes a method and device for honing a metal strip of arbitrary width in continuous motion, allowing honing that is free of artefacts and automated of a suspended portion of at least one side of a metal strip. The said device comprises: a means of vertically positioning an abrasive element at the surface of the said strip, a means of horizontally moving the abrasive element transversely to the motion of the said strip, the said means being couplable to the vertical-positioning means and able to move back and forth from one edge of the strip to the other, a first means allowing uniform pressure to be applied to press the abrasive element against the metal strip, and is characterized in that the said first means allows a uniform pressure to be applied to a suspended portion of strip in motion and can be coupled to a second means that allows the said pressure to be adjusted according to the longitudinal tension of the suspended portion of strip.
