Grinding disk e.g. scrubbing- and/or separation disks, for machining work pieces, has carrier- and grinding layers joined together with damping layer by common treatment by supplying energy, where damping layer includes recesses or gaps

摘要

The grinding disk (1) has carrier- and grinding layers (4, 7) provided with a synthetic resin-bound carrier material and grinding bodies. A damping layer (5) is provided with a damping material formed of elastomer or elastomer mixture. The carrier- and grinding layers are joined together with the damping layer by common treatment by supplying energy. The damping layer includes recesses or gaps (6) partially filled by the carrier material of the carrier- and grinding layers and/or an adhesive layer connected with the carrier- and grinding layers. The carrier- and grinding layers are embedded with a core, which is provided in form of fabric material or fiber material selected from a group consisting of glass fiber, nylon fiber, polyester fiber, carbon fiber, viscose fiber, aramide fiber, metal fiber, aluminum oxide fiber, silicon carbide fiber or fiber with mineral basalt or mineral wool. An independent claim is also included for a method for manufacturing a grinding disk.
