Description
Stand der TechnikState of the art
Es ist bereits ein Verfahren zur Herstellung einer Schleifeinheit vorgeschlagen worden.A method of manufacturing a grinding unit has already been proposed.
Offenbarung der ErfindungDisclosure of the invention
Die Erfindung geht aus von einem Verfahren zur Herstellung einer Schleifeinheit, die zumindest einen Grundkörper und mehrere, fest mit dem zumindest einen Grundkörper verbundene Schleifelemente umfasst.The invention is based on a method for producing a grinding unit which comprises at least one main body and a plurality of grinding elements fixedly connected to the at least one main body.
Es wird vorgeschlagen, dass das Verfahren zumindest einen Verfahrensschritt umfasst, in dem zumindest eine Oberfläche des Grundkörpers zumindest teilweise chemisch und/oder physikalisch bearbeitet wird. Unter einem „Schleifelement“ soll in diesem Zusammenhang insbesondere ein Element verstanden werden, das ein zu bearbeitendes Werkstück in einem Bearbeitungszustand zumindest teilweise direkt kontaktiert und das in einem Bearbeitungszustand zu einem abrasiven Materialabtrag des zu bearbeitenden Werkstücks steht. Der zumindest eine Grundkörper kann vorzugsweise zumindest teilweise aus einem Papier und/oder aus einem Gewebematerial und/oder aus einem Folienmaterial besteht. Unter einem „Papier“ soll in diesem Zusammenhang insbesondere ein Material verstanden werden, das zumindest teilweise aus Fasern, insbesondere aus Pflanzenfasern, vorzugsweise zumindest teilweise durch Verfilzen und Verleimen hergestellt ist und zumindest teilweise zu einer, insbesondere dünnen und glatten, Schicht gepresst ist. Unter einem „Gewebematerial“ soll in diesem Zusammenhang insbesondere ein Material verstanden werden, das zumindest teilweise gewebt ist und aus sich kreuzenden Fasern, insbesondere Fäden, besteht. Unter einem „Folienmaterial“ soll in diesem Zusammenhang insbesondere ein Material verstanden werden, das zumindest teilweise aus zumindest einem Metall, aus zumindest einer Metalllegierung und/oder aus zumindest einem Kunststoff besteht und das zumindest teilweise in, insbesondere sehr dünnen, Bahnen hergestellt ist.It is proposed that the method comprises at least one method step in which at least one surface of the base body is at least partially processed chemically and / or physically. In this context, a "grinding element" is to be understood as meaning, in particular, an element which at least partially directly contacts a workpiece to be machined in a processing state and which is in an operating state an abrasive material removal of the workpiece to be machined. The at least one main body can preferably at least partially consist of a paper and / or of a fabric material and / or of a film material. A "paper" is to be understood in this context, in particular a material which is at least partially made of fibers, in particular from plant fibers, preferably at least partially by felting and gluing and at least partially pressed to a, in particular thin and smooth, layer. In this context, a "fabric material" should be understood in particular to mean a material which is at least partially woven and consists of intersecting fibers, in particular threads. In this context, a "film material" is to be understood as meaning, in particular, a material which at least partially consists of at least one metal, at least one metal alloy and / or at least one plastic and which is produced at least partially in, in particular very thin, webs.
Unter „chemisch und/oder physikalisch bearbeiten“ soll in diesem Zusammenhang insbesondere eine, insbesondere dauerhafte, Veränderung der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit zumindest teilweise unter einer Einwirkung zumindest einer Kraft und/oder durch zumindest einen chemischen Prozess verstanden werden.By "chemically and / or physically processing" in this context is meant, in particular, a permanent change of the at least one surface of the at least one main body of the grinding unit at least partially under the action of at least one force and / or by at least one chemical process.
Durch die erfindungsgemäße Ausgestaltung des Verfahrens kann auf bevorzugt einfache Weise eine vorteilhaft gründliche und zuverlässige Bearbeitung der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit erreicht werden.As a result of the configuration of the method according to the invention, an advantageously thorough and reliable machining of the at least one surface of the at least one main body of the grinding unit can be achieved in a preferably simple manner.
Ferner wird vorgeschlagen, dass die Oberfläche des zumindest einen Grundkörpers in dem Verfahrensschritt zumindest teilweise aufgeraut wird. Unter „aufrauen“ soll in diesem Zusammenhang insbesondere eine, insbesondere mechanische, Einbringung von Unebenheiten in die zumindest eine Oberfläche des zumindest einen Grundkörpers der Schleifeinheit verstanden werden, wobei die Unebenheiten insbesondere weniger als 10 mm, vorzugsweise weniger als 5 mm, bevorzugt weniger als 1 mm und besonders bevorzugt weniger als 0,5 mm und insbesondere zumindest 0,005 mm, vorzugsweise zumindest 0,01 mm, bevorzugt zumindest 0,05 mm und besonders bevorzugt zumindest 0,1 mm über eine Haupterstreckungsebene der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit hinaus- und/oder hineinragen. Dadurch können auf konstruktiv einfache Weise eine vorteilhaft große Flächenerstreckung der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit und eine bevorzugt zuverlässige Haftung der Grund- und/oder Haftbindeschicht auf der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit erreicht werden.It is also proposed that the surface of the at least one main body is at least partially roughened in the method step. In this context, "roughening" is to be understood in particular as meaning a, in particular mechanical, introduction of unevenness into the at least one surface of the at least one main body of the grinding unit, the unevenness being in particular less than 10 mm, preferably less than 5 mm, preferably less than 1 mm and more preferably less than 0.5 mm and in particular at least 0.005 mm, preferably at least 0.01 mm, preferably at least 0.05 mm and particularly preferably at least 0.1 mm over a main extension plane of the at least one surface of the at least one main body of the grinding unit out and / or protrude. As a result, an advantageously large areal extent of the at least one surface of the at least one main body of the grinding unit and a preferably reliable adhesion of the base and / or adhesive bond layer to the at least one surface of the at least one main body of the grinding unit can be achieved in a structurally simple manner.
Des Weiteren wird vorgeschlagen, dass die Oberfläche des zumindest einen Grundkörpers in dem Verfahrensschritt zumindest teilweise gereinigt wird. Unter „reinigen“ soll in diesem Zusammenhang insbesondere eine zumindest teilweise Entfernung von unerwünschten Stoffen, Stoffgemischen und/oder Partikeln, die sich auf der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit ablagern, von der Grund- und/oder Haftbindeschicht auf der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit verstanden werden. In einem besonders bevorzugten Ausführungsbeispiel werden in dem Verfahrensschritt Staub und Fettrückstände von der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit zumindest teilweise entfernt. Dadurch kann eine negative Beeinträchtigung der Haftung der Grund- und/oder Haftbindeschicht auf der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit zumindest verringert und besonders bevorzugt nahezu vollständig verhindert werden.Furthermore, it is proposed that the surface of the at least one main body is at least partially cleaned in the method step. In this context, "cleaning" is intended in particular to mean at least partial removal of undesired substances, mixtures of substances and / or particles deposited on the at least one surface of the at least one main body of the grinding unit from the base and / or adhesive layer on the at least one Surface of the at least one main body of the grinding unit to be understood. In a particularly preferred embodiment, in the method step, dust and fat residues are at least partially removed from the at least one surface of the at least one main body of the grinding unit. As a result, a negative impairment of the adhesion of the base and / or adhesive layer on the at least one surface of the at least one main body of the grinding unit can at least be reduced and particularly preferably almost completely prevented.
Zudem wird vorgeschlagen, dass das Verfahren zumindest einen weiteren Verfahrensschritt aufweist, in dem eine Grund- und/oder Haftbindeschicht zumindest teilweise auf die zumindest teilweise chemisch und/oder physikalisch bearbeitete Oberfläche des zumindest einen Grundkörpers aufgebracht wird. Unter einer „Grund- und/oder Haftbindeschicht“ soll in diesem Zusammenhang insbesondere ein insbesondere flächig ausgedehnt angeordneter Stoff oder angeordnetes Stoffgemisch verstanden werden, das in Normalenrichtung einer Haupterstreckungsfläche des zumindest einen Grundkörpers der Schleifeinheit, insbesondere direkt, zwischen der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit und den Schleifelementen angeordnet ist. Die Grund- und/oder Haftbindeschicht ist vorzugsweise zumindest teilweise zu einer stoffschlüssigen Verbindung der Schleifelemente und des zumindest einen Grundkörpers der Schleifeinheit vorgesehen. Dadurch kann eine bevorzugt gute und zuverlässige Haftung und stoffschlüssige Verbindung der Grund- und/oder Haftbindeschicht auf der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit erreicht werden.In addition, it is proposed that the method has at least one further method step in which a base and / or adhesive layer is at least partially applied to the at least partially chemically and / or physically processed surface of the at least one base body. Under a "primer and / or adhesive layer" is in this context in particular a in particular flat extensively arranged fabric or arranged substance mixture are understood, which is arranged in the normal direction of a main extension surface of the at least one main body of the grinding unit, in particular directly, between the at least one surface of the at least one main body of the grinding unit and the grinding elements. The base and / or adhesive layer is preferably at least partially provided for a cohesive connection of the grinding elements and the at least one main body of the grinding unit. As a result, a preferably good and reliable adhesion and cohesive connection of the base and / or adhesive layer on the at least one surface of the at least one main body of the grinding unit can be achieved.

Es wird vorgeschlagen, dass die Vorrichtung zumindest eine Bearbeitungseinheit aufweist, die zu einer chemischen und/oder physikalischen Bearbeitung zumindest eines Teils zumindest einer Oberfläche des Grundkörpers vorgesehen ist. Dadurch können auf konstruktiv einfache Weise eine vorteilhaft große Flächenerstreckung der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit und eine bevorzugt zuverlässige Haftung der Grund- und/oder Haftbindeschicht auf der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit erreicht werden.It is proposed that the device has at least one processing unit which is provided for a chemical and / or physical processing of at least one part of at least one surface of the base body. As a result, an advantageously large areal extent of the at least one surface of the at least one main body of the grinding unit and a preferably reliable adhesion of the base and / or adhesive bond layer to the at least one surface of the at least one main body of the grinding unit can be achieved in a structurally simple manner.
Ferner wird vorgeschlagen, dass die zumindest eine Bearbeitungseinheit zumindest ein erstes Bearbeitungselement, das zu einem Aufrauen zumindest des Teils der zumindest einen Oberfläche des Grundkörpers vorgesehen ist, und/oder zumindest ein weiteres Bearbeitungselement, das zu einer Reinigung zumindest des Teils der zumindest einen Oberfläche des Grundkörpers vorgesehen ist, umfasst. Dadurch kann auf konstruktiv einfache Weise eine bevorzugt zuverlässige Haftung der Grund- und/oder Haftbindeschicht auf der zumindest einen Oberfläche des zumindest einen Grundkörpers der Schleifeinheit erreicht werden.It is also proposed that the at least one processing unit has at least one first processing element, which is provided for roughening at least the part of the at least one surface of the base body, and / or at least one further processing element, which is used to clean at least the part of the at least one surface of the Basic body is provided includes. As a result, a preferably reliable adhesion of the base and / or bonding layer to the at least one surface of the at least one main body of the grinding unit can be achieved in a structurally simple manner.
Die Erfindung geht zudem aus von einer Schleifeinheit, die zumindest teilweise mittels eines erfindungsgemäßen Verfahrens und zumindest teilweise mittels einer erfindungsgemäßen Vorrichtung hergestellt ist, mit zumindest einem Grundkörper und mit mehreren Schleifelementen.The invention is also based on a grinding unit, which is at least partially produced by means of a method according to the invention and at least partially by means of a device according to the invention, with at least one main body and with a plurality of grinding elements.
