Abstract

Bei einem Verfahren zum Herstellen einer Trennscheibe (10) wird zu Anfang ein im wesentlichen kreisförmiger Metallgrundkörper (12) mit einer Umfangskante bereitgestellt. Wenigstens ein Schlitz (16) wird in den Metallgrundkörper (12) geschnitten, der sich ausgehend von der Umfangskante erstreckt. Durch Anbringen eines Schneidebelags (14) an zumindest einem Teil der Umfangskante des Metallgrundkörpers ist die Trennscheibe (10) im wesentlichen fertiggestellt. Beim Erkalten des Schneidebelags (14) tritt jedoch eine gewisse Schrumpfung desselben auf, die zu Spannungen in dem Metallgrundkörper (12) führen kann, welche jedoch durch den zumindest einen Schlitz (16) aufgenommen werden. Zur Stabilisierung der Trennscheibe (10) kann zum einen der Schneidebelag (14) derart angebracht sein, daß er den Schlitz (16) überbrückt. Zum anderen kann der zumindest eine Schlitz (16) nach dem Erkalten des Schneidebelags (14) teilweise oder ganz verschweißt werden.

Figure 00000001
In a method for producing a cutting disc (10), an essentially circular metal base body (12) with a peripheral edge is initially provided. At least one slot (16) is cut into the metal base body (12), which extends starting from the peripheral edge. The cutting disc (10) is essentially completed by attaching a cutting surface (14) to at least a part of the peripheral edge of the metal base body. When the cutting surface (14) cools down, however, there is a certain shrinkage thereof, which can lead to tensions in the metal base body (12), which, however, are absorbed by the at least one slot (16). To stabilize the cutting disc (10), the cutting surface (14) can be attached in such a way that it bridges the slot (16). On the other hand, the at least one slot (16) can be partially or completely welded after the cutting covering (14) has cooled.
