Verbesserungen des Schleifverhältnisses und der Oberflächengüte. Dieser bekannte Vorschlag ist jedoch nicht für alle Arten von Schleifscheiben anwendbar. Improvements in the grinding ratio and surface quality. However, this known proposal is not applicable to all types of grinding wheels.

Gemäß der Erfindung ist eine Schleifvorrichtung, bei der eine Schleifscheibe zwischen zwei Flanschen auf einer Schleifspindel eingeklemmt ist, dadurch gekennzeichnet, daß ein Scheibenring aus geeignetem elastischem Material, z.B. Kautschuk, zwischen die Schleifscheibe und jeden Flansch eingefügt ist, und daß die Schleifscheibe mit Spielpassung auf der Schleifspindel sitzt.According to the invention is a grinding device in which a grinding wheel is located between two flanges a grinding spindle is clamped, characterized in that a disk ring made of suitable elastic Material such as rubber is interposed between the grinding wheel and each flange, and that the The grinding wheel sits with a clearance fit on the grinding spindle.

Jeder ScheLbenring kann aus Neopren hergestellt sein, und die besten Ergebnisse lassen sich durch Scheibenringe erzielen, bei denen zwischen zwei Metallscheibenringen eine elastische Materialschicht vorgesehen ist*Each cuff ring can be made of neoprene, and the best results can be obtained by using washer rings, where between two metal washer rings an elastic material layer is provided *

Der Ausdruck "Spielpassung" bedeutet, daP die Schleifscheibe sich um die Schleifspindel radial selbst frei justieren kann. Ein Spiel von etwa 0,25 mm ist fcnfriedenstellend. The term "clearance fit" means that the grinding wheel is used can freely adjust itself radially around the grinding spindle. A clearance of about 0.25 mm is satisfactory.

Die Erfindung wird unter Bezug auf die Zeichnung näher erläutert, die einen Schnitt durch die Befestigung eines Umfangsschleifkörpers zeigt, der als DIAI- oder BIAI-Schleifkörper bekannt ist.The invention is explained in more detail with reference to the drawing, which shows a section through the attachment of a Circumferential grinding wheel shows that as DIAI or BIAI grinding wheel is known.

Gemäß dem dargestellten Ausführungsbeispiel ist eine Standard-Diamantschleifscheibe 2 mittels einer Standar-d-Schleifkörperaufnähme, bestehend aus einer Buchse 4 mitAccording to the illustrated embodiment, a standard diamond grinding wheel 2 is made by means of a standard grinding wheel holder, consisting of a socket 4 with

einem festen Flansch 5 und einem Klemmflansch 6 auf der Schleifspindel bzw. -welle 3 befestigt.a fixed flange 5 and a clamping flange 6 attached to the grinding spindle or shaft 3.

Erfindungsgemäß werden zwischen die Flansche 6 und 5 sowie die Schleifscheibe 2 zwei Scheibenringe 7 und 8 eingefügt. Jeder Scheibenring 7 besteht aus einer Schichtung von Neopren-Scheiben 8 und Metallscheiben 9 und 10. Im übrigen ist zwischen dem Innenumfang der Schleifscheibe 2 und der Buchse 4 ein in der Zeichnung übertrieben dargestellter Abstand von etwa 0,25 nun vorhanden. According to the invention, between the flanges 6 and 5 as well as the grinding wheel 2 two disk rings 7 and 8 inserted. Each disc ring 7 consists of one Layering of neoprene discs 8 and metal discs 9 and 10. In addition, between the inner circumference of the grinding wheel 2 and the bush 4 is a in the drawing Exaggerated distance of about 0.25 now available.

In der Praxis hängt die Wirksamkeit der Erfindung davon ab, ob genügend Radialbewegliohkeit bei Unterdrückung von Rattervibrationen vermittelt wird, ohne daß die Seitenflexibilität für die Entwicklung von Vibrationen in dieser Richtung ausreicht. Die Dicke des flexiblen Teiles 8 des Scheibenringes 7 ist zur Anpascris ar; ^i4? jaeeiHtf«« TTmfit.Mnde veränderbar. Auch die von den Klemmschrauben auf dem Klemmflansch 6 hervorgerufene Zusammendrückung kann aus dem gleichen Grunde verändert werden.In practice, the effectiveness of the invention depends on whether sufficient radial mobility is imparted to suppress chatter vibrations without sufficient lateral flexibility to develop vibrations in that direction. The thickness of the flexible part 8 of the disk ring 7 is to be adjusted; ^ i 4 ? jaeeiHtf «« TTmfit.Mnde changeable. The compression caused by the clamping screws on the clamping flange 6 can also be changed for the same reason.

In der Praxis erwies sich ein Scheibenring aus Lagen 8, 9 und 10 von jeweils 1 mm Dicke bei einer harzgebundenen DIAL-Schleifscheibe als zweckmäßig, die zum Schleifen eines Wolframkarbid-Versuehsstückes verwendet wurde.In practice, a washer ring made up of layers 8, 9 and 10, each 1 mm thick, has proven to be a resin-bonded one DIAL grinding wheel as appropriate for the Used to grind a tungsten carbide test piece would.

Es hat sich gezeigt, daß radiale Rattervibrationen unterdrückt wurden, daß ein besseres Schleifverhältnis erzielt wurde, und daß die Oberflächengüte erheblichIt was found that radial chatter vibrations were suppressed, that a better grinding ratio has been achieved and that the surface quality is considerable

gesteigert werden konnte. Die Verbesserung der Oberflächengüte ergab sich bei allen normalen Schleifgesohwindigkeiten. Der Vorteil reduzierter Rattervibrationen und verbesserter Schleifverhältnisse wurde besonders bemerkenswert bei Schleifscheiben-Umfangsgeschwindigkeiten über 40 m/sec.could be increased. The improvement in surface quality resulted at all normal grinding speeds. The advantage of reduced chatter vibrations and improved grinding ratios became particularly noticeable at grinding wheel peripheral speeds of over 40 m / sec.
