Disc tool

A disc tool for a processing machine for grinding and/or polishing a workpiece, wherein the disc tool comprises:

• a carrier for attachment to an output of the processing machine,
• a cushion element made of elastic material arranged on the carrier;
• and
• a retaining wall element for retaining the cushion element arranged on the carrier,
• wherein the retaining wall element is retained on the carrier by means of retaining bolts, wherein respective bolt portions of the retaining bolts extending along respective bolt longitudinal axes and extending through respective retaining bolt passage openings of the retaining wall element are accommodated in respective retaining mounts of the carrier, and the retaining wall element is held between bolt heads of the retaining bolts and the carrier, and
• wherein an adhesive layer is arranged on a side of the retaining wall element opposite the carrier, and
• wherein a processing means for grinding and/or polishing the workpiece is releasably attached to the adhesive layer, and
• wherein the adhesive layer has recesses associated with the bolt heads, the recesses being present before the retaining bolts are screwed into the carrier and cross-sections of the recesses provided to mount the bolt heads are greater than cross-sections of the retaining bolt passage openings respectively, and
• wherein the disc tool further comprises an adhesive layer element which has an adhesive layer wall with the adhesive layer and is arranged on the retaining wall element, and
• wherein the adhesive layer element has at least one adhesive layer cushion element made of an elastic material arranged between the adhesive layer wall and the retaining wall element.
