Definitions
- the present invention relates to a preferably flat abrasive body, comprising a carrier material and an abrasive applied to the carrier material abrasive.
- Such abrasive bodies are known for example as grinding wheels or flowers on the market and can be applied for machining a variety of surfaces on eccentric grinder, orbital sanders, rubber blocks or the like.
- grinding wheels are used with abrasives of different grain size, which remove height differences by a plane-parallel, mechanically or manually executed movement on the surface. This removal process is carried out either dry or with the addition of water-like liquids. Afterwards the finished lacquer surface is polished to a high gloss with a rotating polishing plate and polishing paste.
- the aim of such a treatment is that the painted surface then runs absolutely plane-parallel to the underlying support material and differs in gloss and surface structure in any way from the raw, adjacent paint surface.
- the DE 28 05 288 A1 discloses an abrasive sheet which is provided on the back with a reinforcing layer of flexible material which preferably projects beyond the edge of the abrasive sheet and thus is intended to provide protection against grinding in of grooves with the abrasive sheet edge. In principle, however, scoring can not be reliably avoided even with such an arrangement, for example when the flexible material buckles away.
- an abrasive article is disclosed, which is provided in the outer edge region with a zone of an elastic material. This serves primarily for the purpose of preventing break-off of grinding comagglomerates or individual abrasive grains from the edge of the abrasive article.
- a generic grinding wheel is from the US 152 127 A in which an abrasive-free edge region of the abrasive body is formed in that the abrasive is applied only in an inner circular area, forming the abrasive-free edge region by releasing the carrier material of abrasives.
- Object of the present invention is to develop a generic abrasive in a simple and cost-effective manner such that an undesirable scoring can be reliably prevented.
- the abrasive-free edge region by a material which smoothes the structure of the abrasive.
- the outer edges of the abrasive body with curved surfaces or uneven placement of the abrasive article on the surface to be machined can not cut into this.
- the material removal takes place in the new abrasive body only by the adjoining the edge to the inside central region of the abrasive body.
- the smoothing of the abrasive structure can be carried out such that the material completely covers the abrasive in the edge region or that it fills the pores between the grains of the abrasive. In both cases, the abrasive action in the treated areas is eliminated.
- the material is a mineral or a polymeric material.
- Gypsum may be particularly preferred as a mineral material, while a two-component paint or a two-component polyester resin may be used as the polymeric material.
- the inventively preferred layer thickness of the smoothing material is 30 to 40 microns. Depending on the grain size of the abrasive, it is ensured with such a layer thickness that the individual grains of the abrasive completely coated or at least the pores between the individual grains are filled. In this way, the abrasive body loses its abrasive effect in the treated edge area.
- the smoothing of the structure of the abrasive material can be applied for example by screen printing, pad printing, spray painting, stamping, brushing, dipping or sticking. In principle, any method is suitable by which the smoothing material can be applied evenly to the edge region of the grinding wheel.
- a carrier material of the abrasive article serves as a carrier material of the abrasive article, a tissue, a paper, a plastic film or a carrier plate.
- a plastic film a film of polyvinyl chloride (PVC) can be used with particular preference.
- the abrasive is preferably arrested by a binder.
- a connecting means for connecting the abrasive body with a grinding device such as an eccentric or orbital sander applied.
- a grinding device such as an eccentric or orbital sander
- This may be, for example, adhesive, which, as long as the abrasive body is not in use, is provided with a cover.
- the abrasive article may be applied to a sander, for example, with the aid of a hook and loop fastener formed from a hook and eye loop.
- the abrasive of the abrasive article according to the invention preferably has a grain size in a range between 2500 and 7000, particularly preferably a grain size of 3000. Granulations in this area are particularly suitable for the post-processing of defects in painted surfaces, such as automobile bodies.
- the support material of the abrasive article according to the invention preferably has a thickness between 30 and 70 .mu.m, particularly preferably a thickness of 50 .mu.m.
- FIG. 1 and FIG. 2 show a designated as a whole by 1 inventive abrasive body, as used for example in the automotive industry for post-processing of defects in paint surfaces used.
- the grinding wheel 1 is designed as a grinding flower with a corrugated edge. As a result, transitions between surfaces of different curvature can be processed more advantageously.
- the grinding body 1 has an upper side 10, a lower side 11 and an edge 100.
- the abrasive body 1 is composed of several layers.
- a carrier material 5 is arranged, which consists of a fabric on the carrier material by means of a binder 4, an abrasive 2 applied with a 3000 grit adhesion.
- an adhesive 6 which serves for the safe application of the grinding wheel 1 to a grinding tool, not shown here, for example an eccentric or orbital sander.
- the adhesive is first provided with a cover film 7, which is removed before the application of the grinding wheel 1 on the grinding tool.

Description
Die vorliegende Erfindung betrifft einen vorzugsweise flächigen Schleifkörper, umfassend ein Trägermaterial sowie ein auf das Trägermaterial haftend aufgebrachtes Schleifmittel.The present invention relates to a preferably flat abrasive body, comprising a carrier material and an abrasive applied to the carrier material abrasive.
Derartige Schleifkörper sind beispielsweise als Schleifscheiben oder -blüten auf dem Markt bekannt und können zur Bearbeitung verschiedenster Oberflächen auf Exzenterschleifer, Schwingschleifer, Gummiklötze oder ähnliches aufgebracht werden.Such abrasive bodies are known for example as grinding wheels or flowers on the market and can be applied for machining a variety of surfaces on eccentric grinder, orbital sanders, rubber blocks or the like.
Insbesondere werden sie, z.B. in der Automobilindustrie, zur Nachbearbeitung von Fehlstellen in Lackoberflächen eingesetzt. Dazu werden Schleifkörper mit Schleifmitteln unterschiedlicher Körnung verwendet, welche durch eine planparallele, maschinell oder manuell ausgeführte Bewegung auf der Oberfläche Höhenunterschiede abtragen. Dieser Abtragungsprozess wird entweder trocken oder mit Zugabe von wasserähnlichen Flüssigkeiten durchgeführt. Anschließend wird die nachgearbeitete Lackoberfläche mit einem rotierenden Polierteller und Polierpaste auf Hochglanz poliert.In particular, they are used, e.g. used in the automotive industry, for post-processing of defects in paint surfaces. For this purpose, grinding wheels are used with abrasives of different grain size, which remove height differences by a plane-parallel, mechanically or manually executed movement on the surface. This removal process is carried out either dry or with the addition of water-like liquids. Afterwards the finished lacquer surface is polished to a high gloss with a rotating polishing plate and polishing paste.
Ziel einer derartigen Nachbehandlung ist es, dass die lackierte Oberfläche anschließend absolut planparallel zu dem darunter befindlichen Trägerwerkstoff verläuft und sich in Glanz und Oberflächenstruktur in keiner Weise von der unbearbeiteten, angrenzenden Lackoberfläche unterscheidet.The aim of such a treatment is that the painted surface then runs absolutely plane-parallel to the underlying support material and differs in gloss and surface structure in any way from the raw, adjacent paint surface.
Eine derartige Vorgehensweise gestaltet sich als schwierig, sobald die zu behandelnden Oberflächen konkav ausgebildet sind. Hier bilden sich durch die Außenkanten des Schleifmittels rund um die üblicherweise recht kleinflächige zu bearbeitende Fläche großflächige Schleifriefen und Abtragungen in Gestalt einer Kreisringfläche oder in Form einer Mondsichel.Such a procedure is difficult as soon as the surfaces to be treated are concave. Here are formed by the outer edges of the abrasive around the usually quite small area to be machined surface large grinding marks and erosion in the form of a circular ring surface or in the shape of a crescent moon.
Darüber hinaus kann es auch bei der Bearbeitung ebener Flächen durch ein nicht exakt planparalleles Aufsetzen des Schleifkörpers auf die Oberfläche und den damit verbundenen exponierten Abtrag der Schleifkörperkanten zur Ausbildung von sichelförmigen oder linienförmigen Vertiefungen kommen, was einen beträchtlichen Nachbearbeitungsaufwand bedeutet.In addition, it can also be when machining flat surfaces by not exactly plane-parallel placement of the abrasive article on the surface and the so connected exposed removal of the abrasive body edges to form sickle-shaped or linear depressions, which means a considerable Nachbearbeitungsaufwand.

Aufgabe der vorliegenden Erfindung ist es, einen gattungsgemäßen Schleifkörper in einfacher und kostengünstiger Weise derart weiterzubilden, dass eine unerwünschte Riefenbildung sicher verhindert werden kann.Object of the present invention is to develop a generic abrasive in a simple and cost-effective manner such that an undesirable scoring can be reliably prevented.
Diese Aufgabe wird gelöst durch einen Schleifkörper mit den Merkmalen des Patentanspruchs 1.This object is achieved by an abrasive body having the features of patent claim 1.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments and modifications of the invention are the subject of the dependent claims.
Nach der Erfindung ist vorgesehen, den abrasivfreien Randbereich durch einen die Struktur des Schleifmittels glättenden Werkstoff zu schaffen.According to the invention, it is provided to provide the abrasive-free edge region by a material which smoothes the structure of the abrasive.
In jedem Fall wird erreicht, dass sich die Außenkanten des Schleifkörpers bei gekrümmten Oberflächen oder bei unebenem Aufsetzen des Schleifkörpers auf die zu bearbeitende Oberfläche nicht in diese einschneiden können. Der Materialabtrag erfolgt bei dem neuen Schleifkörper lediglich durch den sich an den Rand nach innen anschließenden zentralen Bereich des Schleifkörpers.In any case, it is achieved that the outer edges of the abrasive body with curved surfaces or uneven placement of the abrasive article on the surface to be machined can not cut into this. The material removal takes place in the new abrasive body only by the adjoining the edge to the inside central region of the abrasive body.
Die Glättung der Schleifmittelstruktur kann dabei derart erfolgen, dass der Werkstoff das Schleifmittel im Randbereich komplett überzieht oder aber dass er die Poren zwischen den Körnern des Schleifmittels auffüllt. In beiden Fällen wird die Schleifwirkung in den behandelten Bereichen eliminiert.The smoothing of the abrasive structure can be carried out such that the material completely covers the abrasive in the edge region or that it fills the pores between the grains of the abrasive. In both cases, the abrasive action in the treated areas is eliminated.
Bei einer weiteren bevorzugten Ausführung der Erfindung handelt es sich bei dem Werkstoff um einen mineralischen oder einen polymeren Werkstoff. Als mineralischer Werkstoff kann besonders bevorzugt Gips vorgesehen sein, während als polymerer Werkstoff ein zweikomponentiger Lack oder ein zweikomponentiges Polyesterharz zum Einsatz kommen kann. Grundsätzlich ist bei der Materialauswahl darauf zu achten, dass das Material der durch Reibung erzeugten Wärmeentwicklung während des Schleifprozesses standhält.In a further preferred embodiment of the invention, the material is a mineral or a polymeric material. Gypsum may be particularly preferred as a mineral material, while a two-component paint or a two-component polyester resin may be used as the polymeric material. When selecting materials, it is important to ensure that the material withstands the heat generated by friction during the grinding process.
Die erfindungsgemäß bevorzugte Schichtdicke des glättenden Werkstoffs beträgt 30 bis 40 µm. In Abhängigkeit von der Korngröße des Schleifmittels ist bei einer derartigen Schichtdicke gewährleistet, dass die einzelnen Körner des Schleifmittels komplett überzogen oder aber zumindest die Poren zwischen den einzelnen Körnern aufgefüllt sind. Auf diese Weise verliert der Schleifkörper seine Schleifwirkung in dem behandelten Randbereich.The inventively preferred layer thickness of the smoothing material is 30 to 40 microns. Depending on the grain size of the abrasive, it is ensured with such a layer thickness that the individual grains of the abrasive completely coated or at least the pores between the individual grains are filled. In this way, the abrasive body loses its abrasive effect in the treated edge area.
Der die Struktur des Schleifmittels glättende Werkstoff kann beispielsweise durch Siebdruck, Tampondruck, Sprühlackierung, Stempeln, Aufstreichen, Tauchen oder Aufkleben aufgebracht werden. Grundsätzlich ist jedes Verfahren geeignet, durch welches der glättende Werkstoff gleichmäßig auf den Randbereich des Schleifkörpers aufgetragen werden kann.The smoothing of the structure of the abrasive material can be applied for example by screen printing, pad printing, spray painting, stamping, brushing, dipping or sticking. In principle, any method is suitable by which the smoothing material can be applied evenly to the edge region of the grinding wheel.
Bei einer bevorzugten Ausführungsform der vorliegenden Erfindung dient als Trägermaterial des Schleifkörpers ein Gewebe, ein Papier, eine Kunststofffolie oder eine Trägerplatte. Als Kunststofffolie kann besonders bevorzugt eine Folie aus Polyvinylchlorid (PVC) eingesetzt werden.In a preferred embodiment of the present invention serves as a carrier material of the abrasive article, a tissue, a paper, a plastic film or a carrier plate. As a plastic film, a film of polyvinyl chloride (PVC) can be used with particular preference.
Mit dem jeweiligen Trägermaterial ist das Schleifmittel bevorzugt durch ein Bindemittel verhaftet.With the respective carrier material, the abrasive is preferably arrested by a binder.
Auf der dem Schleifmittel abgewandten Seite des Trägermaterials ist bei einer vorteilhaften Ausgestaltung der Erfindung ein Verbindungsmittel zur Verbindung des Schleifkörpers mit einem Schleifgerät, beispielsweise einem Exzenter- oder Schwingschleifer, aufgebracht. Hierbei kann es sich beispielsweise um Klebstoff handeln, der, solange der Schleifkörper nicht in Benutzung ist, mit einer Abdeckfolie versehen ist. Alternativ kann der Schleifkörper beispielsweise auch mit Hilfe eines aus einem Haken- und einem Ösenband gebildeten Klettverschlusses auf ein Schleifgerät aufgebracht werden.On the side of the carrier material facing away from the abrasive, in an advantageous embodiment of the invention, a connecting means for connecting the abrasive body with a grinding device, such as an eccentric or orbital sander applied. This may be, for example, adhesive, which, as long as the abrasive body is not in use, is provided with a cover. Alternatively, the abrasive article may be applied to a sander, for example, with the aid of a hook and loop fastener formed from a hook and eye loop.
Das Schleifmittel des erfindungsgemäßen Schleifkörpers weist vorzugsweise eine Körnung in einem Bereich zwischen 2500 und 7000, besonders bevorzugt eine Körnung von 3000 auf. Körnungen in diesem Bereich sind besonders geeignet für die Nachbearbeitung von Fehlstellen in lackierten Oberflächen, beispielsweise Automobilkarosserien.The abrasive of the abrasive article according to the invention preferably has a grain size in a range between 2500 and 7000, particularly preferably a grain size of 3000. Granulations in this area are particularly suitable for the post-processing of defects in painted surfaces, such as automobile bodies.
Das Trägermaterial des erfindungsgemäßen Schleifkörpers weist bevorzugt eine Dicke zwischen 30 und 70 µm, besonders bevorzugt eine Dicke von 50 µm auf.The support material of the abrasive article according to the invention preferably has a thickness between 30 and 70 .mu.m, particularly preferably a thickness of 50 .mu.m.

Im Randbereich des Schleifkörpers 1 ist umlaufend ein die Struktur des Schleifmittels glättender Werkstoff 3 als Abdeckung aufgebracht. Es handelt sich dabei um Gips, welcher durch Aufstreichen auf den Rand 100 sowie auf den an den Rand 100 unmittelbar angrenzenden Bereich auf der schleifmittelseitigen Oberseite 10 des Schleifkörpers 1 aufgebracht wird.In the edge region of the grinding wheel 1, a
Durch diesen Gipsauftrag wird die abrasive Oberflächenstruktur des Schleifkörpers im Randbereich abgedeckt, so dass nur noch die zentrale Schleifmittelfläche im Stande ist, Material abzutragen. Dadurch werden Bearbeitungsspuren und in der Folge Nachbearbeitungszeiten erheblich reduziert.By this gypsum application, the abrasive surface structure of the abrasive body is covered in the edge region, so that only the central abrasive surface is able to remove material. As a result, processing traces and consequently post-processing times are considerably reduced.
Der Schleifkörper 1 zeichnet sich insbesondere dadurch aus, dass der glättende Werkstoff 3 in einfacher und kostengünstiger Weise auf bereits vorhandene Schleifkörper 1 aufgebracht werden kann.The grinding body 1 is characterized in particular by the fact that the smoothing
