摘要： A finishing machine comprises a motor mounted on a support frame and connected to a drive shaft and two or more finishing heads and an impeller fan driven by the drive shaft via a serpentine belt drive which rotates the finishing heads in opposite directions. The impeller fan impels dust from the grinding heads into a rear vacuum manifold and the support frame has rear wheels the height of which is adjustable by means of an hydraulic cylinder.
