GRINDING DEVICE

Abstract

A grinding device includes a support element and a preferably flexible grinding element held thereon. A carrier rests against the support element. A grinding layer is designed in such a way that in a grinding position, the grinding element is held on the support element in a frictionally locking manner.

Claims

1-6. (canceled)

7. A grinding device, comprising: a support element; a flexible grinding means held on the support element, wherein the grinding means consisting of a carrier, which bears against a closed surface of the support element, and a grinding layer, wherein a surface of the carrier facing towards the support element is structured and is held against the support element by frictional engagement across an entire surface of the support element in a grinding position, and wherein a coefficient of friction of the support element and grinding means is between 0.2 and 0.5.

8. The grinding device of claim 7, wherein a friction force generated by pressing the support element against the grinding means is between 0.5 and 2.0 N/mm.sup.2.

9. The grinding device of claim 7, wherein the side of the carrier facing towards the support element is made of a polymer, an elastomer, or leather.

10. The grinding device of claim 7, wherein a thickness of the carrier on the side facing towards the support element is between 0.7 and 4 mm.

12. The grinding device of claim 7, wherein the grinding means is a grinding belt.

Description

BRIEF DESCRIPTION OF THE DRAWING FIGURE

[0029] The single FIGURE shows a grinding device according to the invention in a schematic side view.

DETAILED DESCRIPTION

[0030] The FIGURE shows a grinding device 1 for removing a flaw in a surface, in particular a finished surface, of an object (not shown) by grinding.

[0031] This grinding device 1 has a robot arm 2 and a support element 3 held thereon in the form of a support disc, which support element is movable, for example in an orbital, vibrating or rotating manner, relative to the surface in order to grind the flaw.

[0032] In the grinding position, i.e., in contact with the surface of the object, as shown in the FIGURE, a grinding means 5, in the example in the form of a grinding belt, bears with frictional engagement against the support element 3, wherein the rear side of the grinding means 5, so to speak, which bears against the support element 3, is designed as a carrier, which on the other side carries an abrasive grit that makes contact with the surface of the object.

[0033] The grinding means 5 is held in a dispenser in the form of a cassette 4 and is wound as a roll 6 on an unwinding shaft 7, and is wound onto a winding shaft 8, preferably in cycles, in a manner corresponding to the grinding process.

[0034] The frictional engagement between the support element 3 and the grinding means 5 is released by lifting the support element 3, so that the grinding means 5 can be advanced without hindrance.

[0035] Although the invention has been illustrated and described in detail by way of preferred embodiments, the invention is not limited by the examples disclosed, and other variations can be derived from these by the person skilled in the art without leaving the scope of the invention. It is therefore clear that there is a plurality of possible variations. It is also clear that embodiments stated by way of example are only really examples that are not to be seen as limiting the scope, application possibilities or configuration of the invention in any way. In fact, the preceding description and the description of the FIGURES enable the person skilled in the art to implement the exemplary embodiments in concrete manner, wherein, with the knowledge of the disclosed inventive concept, the person skilled in the art is able to undertake various changes, for example, with regard to the functioning or arrangement of individual elements stated in an exemplary embodiment without leaving the scope of the invention, which is defined by the claims and their legal equivalents, such as further explanations in the description.
