FIELD: mechanical engineering. SUBSTANCE: machine has housing with handle and electric driver made in the form of stator and rotor mounted in housing. The abrasive sandpaper with perforation along the whole surface is fastened on exterior side of drive. The cavity for the lubricant-coolant with slotted nozzle facing abrasive sandpaper is made in housing. The bellows connected with cavity by means of ball-type valve is set up in handle. Two screws are mounted in housing coaxially with stator axis and on different sides from it. The conical surfaces with space turnings are made on the screw ends facing each other. The conical surfaces of screws interact with corresponding conical surfaces made on the ends of stator axis. EFFECT: enhanced quality of polishing. 1 cl, 2 dwg
