An abrading machine in which an abrading shoe and a dust collecting shroud gyrate in unison, there being a hole formed through the shroud and communicating with a stationary cup in all gyrated positions of the shoe and the shroud. When suction is applied to the cup, abrading dust is sucked upwardly around the entire outer periphery of the shoe and passes into the shroud, through the hole, and then into the cup for exhaustion to a dust collecting receptacle.
