Embodiment Construction

[0028] exist figure 1 A side sectional view of a holding body according to the invention, which forms the grinding disc 10 , is shown in FIG. The grinding disc 10 has a cover plate 3 made of fiberglass. The cover plate 3 comprises a plurality of suction holes 5 axially penetrating it, only two of which can be seen here. The cover plate 3 is connected to a metal plate 7 by means of rivets 6 . Fastened to the metal plate 7 is a screw 8 , by means of which the grinding disc 10 can be fastened to a rotary drive of a grinding machine (not shown here). The bolt 8 thus serves as a fastening means.

[0029] In other embodiments not shown here, the sheet metal 7 , the rivet 6 and the screw 8 are not part of the grinding disc 10 but are part of a machine-side receptacle for the grinding disc 10 . In this case, the cover plate 3 forms a fastening device for the grinding wheel 10 by means of which the grinding wheel 10 can be fixed to the drive.

[0030] The grinding wheel 10 has a s...

Abstract

A holding body includes a fastening layer which has a fastening surface configured to fasten a flexible grinding device. The fastening layer includes an air- and dust-permeable material and is substantially full-surface. The fastening layer includes a textile material. The holding body also includes a supporting body which has a supporting surface configured to support a holding surface of the fastening layer. The supporting body is air- and dust-permeable and includes an open-cell foam. A grinding system includes such a holding body and such a flexible grinding device.

Description

technical field [0001] The invention relates to a holder, in particular a grinding disc, for a flexible grinding device, and a grinding system with such a holder and a flexible grinding device. Background technique [0002] Holders in the form of grinding discs of the type described above are described in DE 20 2009 000 880 and in EP 0 781 629 A1. Such a grinding disc has a soft support body, which can consist, for example, of a foam material, and an adhesive or adhesive layer for connection to the flexible grinding device. The flexible grinding device can be, for example, a grinding disc. The known grinding disc has a plurality of bores extending in the axial direction, through which air and grinding dust generated during grinding can be sucked out. These holes penetrate both the soft layer and the adhesive or adhesive layer. [0003] Since the necessary holes produce a characteristic hole pattern for the respective grinding disc, the grinding device that can be used mus...
