Abstract
A grinding tool to be driven by a rotating machine drive comprises a carrier body in the form of a disk. The disk can be attached to the machine drive by means of a connecting element located at approximately the area of the center of rotation. The carrier body has at least one working side equipped with a grinding element. The grinding element takes the form of a disk leaf, i.e. a thin or leaf-like disk disposed radially in relation to the axis of rotation. The periphery of the disk protrudes by a predetermined amount beyond the outer edge of the working side of the carrier body. The grinding element disk comprises at least two disk layers attached to one another. A first layer of the disk is an elastic cushioning layer, and a second layer of the disk is a highly flexible grinding linen.
Claims8
A grinding tool to be driven by a rotating machine drive comprising:
- (a) a carrier body in the form of a disk ring comprising a center sleeve and a collar flange projecting approximately radially from the sleeve, said disk ring being adapted to be coupled for rotation along an axis of rotation to the machine drive at approximately the center of rotation and having at least one working side, said disk ring being thin enough to permit a peripheral area of said disk ring to elastically yield in a transverse plane relative to said disk ring;
- (b) a grinding element comprising at least first and second disk layers resting against each other radially disposed in relation to the axis of rotation on said at least one working side, said first layer extending radially beyond an outer edge at said carrier body, said second layer having an outside diameter such that the second layer projects beyond an outer edge of the first layer by a predetermined amount greater than the thickness of the first layer.
