A hand-held grinding machine, in particular an eccentric grinder, has a machine housing 10 with a rotating grinding tray 11 disposed in a manner spaced apart from the underside 101 of said machine housing. The grinding tray may have a supporting bearer (31, fig 7). A braking device 20 operates between the machine housing and the grinding tray to slow down the rotation of said grinding tray. The braking device consists of a braking member 21 constructed on the grinding tray and a running face constructed on the underside of the housing. The braking member is pressed onto the running surface in a springy manner. The braking member preferably consists of a large number of hook-shaped braking elements 17 which are disposed on a base circle which is concentric with the axis of the grinding tray and are attached to the tray body 12 of the grinding tray in one piece. Alternatively the braking member is constructed as a rubber ring (24, fig 3) attached to the tray body. |
