<p>A machine (1) for machining surfaces is disclosed, comprising a pneumatic motor (3) on which there is provided a grip (10) encompassing the upper part of a frame (2) supporting and bounding the motor compartment (44) of said pneumatic motor (3). Said machine (1) has an inflatable cap (12, 12"') housed in an internal cavity (13) of a deformable grip (10) that is suitable for changing the convexity (11) of the grip (10), and comprising a central inlet port (14) fixed to the top of the underlying frame (2) bounding the motor compartment (44) and suitable for conveying to said cap (12, 12"') the leaked air (50) of the motor compartment (44), the convexity (11) of the grip (10) being variable in function of the inflation of the cap (12, 12"') which is in turn variable in function of the quantity of air (50) leaked from the motor compartment below (44) ( Fig.1 ).</p> |
