<Desc/Clms Page number 1>  <Desc / Clms Page number 1>   Die Erfindung betrifft einen Schleifteller aus Kunststoff zum Schleifen und Entgraten von Schneidwerkzeugen mit einer ebenen Stirnfläche, auf der ein Schleifpapier aufgeklebt ist, und mit einer zylindrischen Aussenmantelfläche sowie mit einem Antriebsstift, der mit einem Ende in das Bohrfutter einer Handbohrmaschine eingreift, wobei die Stirnfläche rauh ist.  The invention relates to a grinding plate made of plastic for grinding and deburring cutting tools with a flat face on which an abrasive paper is glued, and with a cylindrical outer surface and with a drive pin which engages with one end in the chuck of a hand drill, the face being rough is. Ein derartiger Schleifteller ist aus der US 3 510 992 A bekannt.  Such a grinding plate is known from US 3,510,992 A. Der Erfindung liegt die Aufgabe zugrunde, einen Schleifteller zu schaffen, bei dem der Zeitbe- darf für das Schärfen und das Entgraten gegenüber den bekannten Schleiftellern deutlich verrin- gert ist.  The object of the invention is to create a grinding plate in which the time required for sharpening and deburring is significantly reduced compared to the known grinding plates. Gelöst wird diese Aufgabe bei dem eingangs genannten Schleifteller dadurch, dass in der zy- lindrischen Aussenmantelfläche scharfkantige Nuten über der gesamten Höhe der Mantelfläche vor- handen sind.  This task is solved in the abrasive disc mentioned at the outset by having sharp-edged grooves in the cylindrical outer surface over the entire height of the surface. Dadurch, dass ein zuvor mittels des Schleifblattes geschliffenes Schneidwerkzeug mit der mit Nuten versehenen Mantelfläche des Kunststoffschleiftellers in Kontakt gebracht wird, lässt sich der beim Schleifen entstandene Grat leicht entfernen.  The fact that a cutting tool previously ground by means of the sanding sheet is brought into contact with the grooved outer surface of the plastic sanding plate makes it easy to remove the burr that has arisen during the grinding. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend er- läutert Dabei zeigt Fig. 1 eine Schnittdarstellung des Schleiftellers und Fig. An embodiment of the invention is shown in the drawing and is explained below 1 shows a sectional view of the grinding plate and FIG. 2 eine Draufsicht auf die Stirnseite des Schleiftellers. Der Schleifteller 1 besteht aus Kunststoff und weist eine zylindrische Aussenmantelfläche 3 auf. Zentral mittig ist ein Antriebsstift 6 vorgesehen, der mit einer Schulter 7 und mit einem unrunden Endstück 8 versehen ist, welches in das Bohrfutter 9 einer Bohrmaschine eingespannt werden kann und von dieser in Drehung versetzt wird. Die dem Antriebsstift 6 gegen- überliegende Seite ist als im wesentlichen ebene Stirnfläche 2 ausgebildet, wobei die Stirnfläche 2 eine rauhe Oberfläche aufweist, die in Fig. 2 mit 10 bezeichnet ist Mittels eines Klebemittels 5 ist darauf ein Schleifpapier 4 aufgeklebt. 2 shows a plan view of the end face of the grinding plate. The grinding plate 1 is made of plastic and has a cylindrical outer surface 3. A drive pin 6 is provided in the center, which is provided with a shoulder 7 and with a non-circular end piece 8, which can be clamped into the drill chuck 9 of a drill and is rotated by the latter. The side opposite the drive pin 6 is designed as an essentially flat end face 2, the end face 2 having a rough surface, which is denoted by 10 in FIG. 2. An abrasive paper 4 is glued thereon by means of an adhesive 5. Aufgrund der Rauhigkeit der Stirnfläche 2 ist das Schleifpa- pier 4 nicht vollflächig mit der Stirnfläche 2 des Schleiftellers 1 verklebt, sondern haftet nur an denjenigen Stellen fest, die sich wegen der Rauhigkeit über die Oberfläche 10 der Stirnfläche hin- aus erheben. Radial aussen ist der Schleifteller 1 mit einer zylindrischen Aussenmantelfläche 3 ver- sehen. Darin sind axial verlaufende scharfkantige Nuten 11, 11 a eingearbeitet Ein zu schärfendes Schneidwerkzeug wird zunächst an seiner zu schleifenden Stelle mit dem an der Stirnfläche 2 aufgeklebten Schleifpapier 4 in Kontakt gebracht. Dabei ist der Schleifteller 1 in Drehung, sodass der Schärfevorgang stattfinden kann. Es bleibt jedoch am Schneidwerkzeug ein Grat zurück, der noch beseitigt werden muss. Dazu wird das Schneidwerkzeug an die rotierende Aussenmantelfläche 3 gehalten.  Due to the roughness of the end face 2, the abrasive paper 4 is not glued over the entire surface to the end face 2 of the sanding plate 1, but only adheres firmly to those points which, because of the roughness, rise above the surface 10 of the end face. The grinding plate 1 is provided with a cylindrical outer surface 3 radially on the outside. Axially extending sharp-edged grooves 11, 11 a are incorporated therein A cutting tool to be sharpened is first brought into contact at its point to be ground with the abrasive paper 4 glued to the end face 2. The grinding disc 1 is rotating so that the sharpening process can take place. However, a burr remains on the cutting tool that still needs to be removed. For this purpose, the cutting tool is held against the rotating outer surface 3. Durch die dort vorhandenen Nutenil, 11a wird der Grat in kürzester Zeit entfernt. Der gesamte Schärfvorgang dauert nur etwa vier bis fünf Sekunden. Es ergibt sich somit ein erheblicher Zeitvorteil gegenüber dem herkömmlichen Schärfen, bei dem zunächst das eigentliche Schärfen durchgeführt werden muss, dem sich dann noch ein separater Arbeitsgang zum Entgraten anschliessen muss. Der erfindungsgemässe Schleifteller 1 ist überall dort anwendbar, wo eine geeignete Antriebsmaschine, wie etwa eine Bohrmaschine, zur Verfügung steht. Als Bei- spiel sei der Einsatz auf Baustellen genannt.  The ridge is removed in a very short time by the grooves 11a present there. The entire sharpening process only takes about four to five seconds. This results in a considerable time advantage compared to conventional sharpening, in which the actual sharpening must first be carried out, which must then be followed by a separate work step for deburring. The grinding plate 1 according to the invention can be used wherever a suitable drive machine, such as a drilling machine, is available. As an example, use on construction sites may be mentioned. Der Schleifteller 1 ist einfach in der Handhabung und kann auch von Laien ohne Schwierigkeiten verwendet werden PATENTANSPRUCH: Schleifteller aus Kunststoff zum Schleifen und Entgraten von Schneidwerkzeugen mit einer ebenen Stirnfläche, wobei auf der Stirnfläche ein Schleifpapier aufgeklebt ist, und mit einer zy- lindrischen Aussenmantelfläche sowie mit einem Antriebsstift, der mit einem Ende mit dem Schleifteller verbunden ist und mit dem anderen Ende in das Bohrfutter einer Handbohrma- schine eingreift, wobei die Stirnfläche (2) rauh ist, dadurch gekennzeichnet, dass in der zylind- rischen Aussenmantelfläche (3) scharfkantige Nuten (11, 11a) über der gesamten Höhe der Aussenmantelfläche (3) vorhanden sind. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**.  The grinding plate 1 is easy to use and can also be used by laypersons without difficulty PATENT CLAIM: Plastic grinding disc for grinding and deburring cutting tools with a flat end surface, with an abrasive paper being glued to the end surface, with a cylindrical outer surface and with a drive pin that has one end with the Grinding plate is connected and engages with the other end in the chuck of a hand drill, the end face (2) being rough, characterized in that sharp-edged grooves (11, 11a) in the cylindrical outer surface (3) over the entire height the Outside surface (3) are available. ** WARNING ** End of CLMS field knows overlap beginning of DESC **.
