Abstract
A disk grinding machine includes a grinding disk (5a), driven by a driving shaft. A handle projects laterally out of a machine housing and is covered by the machine housing. A dust suction installation with a suction hood is provided which covers the upper side of the grinding disk and overlaps its circumference. The installation contains a suction chamber having a bristle rim at its lower end which is fastened to the machine housing. The bristle rim extends only over a part of the circumference of the suction hood. The grinding dust is picked up through the area between the circumference of the grinding disk and the bristle rim and to the suction chamber (11a). The upper part of the suction hood is connected to the machine casing and a lower part of the hood is disposed pivotally and independent from the grinding disk and it supports a bristle rim. A handle for the machine comprises a control grip which is in a driving connection with the lower part of the hood through a drive.
