Abstract
A method of producing an abrasive tool, comprising the steps of preparing a blank of an abrasive tool including abrasing grains in a bond; placing the thusly formed blank in a container; covering the thusly formed blank in the container with at least a protective material; applying a glass material in the container so as to close the container and to form a lock which prevents penetration of an outside atmosphere through the lock into an interior of the container and at the same time allows escape of gases and contaminant from the interior of the container outside; placing the container into a heating device and providing in the heating device a temperature allowing melting of the glass material and creating the lock and also providing sintering of the blanks in the interior of the container; removing the container from the heating device after the sintering; breaking the lock and removing the sintered blanks which form the abrasive tools from the container.
