Abstract: A method and a machine for automatically changing a disc tool to a tool holder of an automated machine working with the disc tools is disclosed. The method includes in the disc tool replacement machine: determining that the tool holder is in a replacement area in the disc tool replacement machine; unfastening a fixing member of the tool holder by applying an unfastening force to the fixing member, wherein the fixing member fixes a disc tool to a backing plate of the tool holder through a through hole at a centre of the disc tool; removing the disc tool from the tool holder after said unfastening; inserting a new disc tool to the tool holder; and fastening the fixing member of the tool holder by applying a fastening force to the fixing member, thus fixing the disc tool to the backing plate of the tool holder through the through hole.

Abstract: A machining tool includes a power transmission mechanism, a circular machining belt, a tightening mechanism and a contact mechanism for tool contact with an object to be machined. The power transmission mechanism of the machining tool has a mechanical connection with a rotational power source. The contact mechanism and the power transmission mechanism have a desired distance therebetween. The circular machining belt is looped between the contact mechanism and the power transmission mechanism for causing the circular machining belt to move between the contact mechanism and the power transmission mechanism in response to the rotation of the power transmission mechanism for machining the object. The tightening mechanism is configured to press sections of the circular machining belt between the contact mechanism and power transmission mechanism towards each other.
