A method for primarily extending the useful lifespan of ceramic tools (1) intended for working primarily metallic material, the tool being brought automatically to a high temperature, at least with regard to certain ceramic parts, when in use, and in which tool ceramic parts thereof form material contacting parts. The method is particularly characterized in that ceramic parts (1) of the tool are heated with the aid of microwaves prior to and/or at least periodically during the time the tool is in operational use, and the tool is caused to include ceramic material which exhibits a significant loss factor with regard to microwaves. The invention also relates to an arrangement for carrying out the method. |
