Abstract

A method of recoating an abrasive tool, wherein the abrasive tool includes a main tool body, which has at least one accommodating surface for accommodating abrasive bodies, wherein the abrasive bodies are adhesively bonded to the accommodating surface by an adhesive. The method includes at least the following steps: degenerating the adhesive, detaching the worn-out abrasive bodies from the main tool body, detaching the degenerated adhesive from the main tool body, reapplying the adhesive; and recoating the main tool body with new abrasive bodies.

First claim

1 .- 11 . (canceled)

12 . A method for recoating an abrasive tool, wherein the abrasive tool comprises a main tool body, which comprises at least one accommodating surface for accommodating abrasive bodies, wherein the abrasive bodies are adhesively bonded to the accommodating surface by means of an adhesive, wherein the method comprises:
degenerating the adhesive, detaching, from the main tool body, the worn-out abrasive bodies, detaching, from the main tool body, the degenerated adhesive, reapplying the adhesive, and recoating the main tool body with new abrasive bodies.

13 . The method of claim 12 , including introducing heat into the adhesive to degenerate the adhesive.

14 . The method of claim 12 , including bringing an organic acid into contact with the adhesive to degenerate the adhesive.

15 . The method of claim 14 , wherein the organic acid is acetic acid.

16 . The method of claim 12 , wherein the adhesive is a 2-component epoxy-adhesive system.

17 . The method of claim 16 , wherein the 2-component epoxy-adhesive system used is an amine-cured adhesive system.

18 . The method of claim 12 , wherein the main tool body provided is a CFRP main body.

19 . A recoatable abrasive tool which is recoated according to the method of claim 12 .

20 . The recoatable abrasive tool of claim 19 , wherein the abrasive bodies are adhesively bonded to the main tool body by an adhesive which can be degenerated at least by means of heat or by means of an organic acid.

21 . The recoatable abrasive tool of claim 19 , wherein the adhesive comprises at least one 2-component epoxy-adhesive system, or the main tool body comprises a CFRP material.

22 . The recoatable abrasive tool of claim 19 , wherein the adhesive is capable of being degenerated by means of an acetic acid.
