The invention relates to a portable hand-driven rotary surface-finishing machine transmitting the motion from the electromotor 1 towards the smoothing disk, via the revs reduction system 40, the shaft 27 transmitting the motion from the reducer, theflexible driving shaft 4 and the driving transmission shaft 15. The planetary rev reducer 32 is air cooled by the vanes 37. The produced powder is confined by the brush into the disk hub 18 and therefrom conducted through the flexible powder-suckingpipe 14 and the pipe bearing the driving transmission shaft towards the exit 25. The smoothing disk is adhered to the elastic plateau 22, it is rotating about the two vertical shafts into the space, through the system consisted of the driving base and the nest of friction rollers 9 interconnected with the rotation screws 7B, while the driving base 6 is connected to the pipe bearing the driving shaft transmitting the motion from the reducer 2 via the rotary screws 7A. |
