Abstract

An improved dry barrel finishing machine is described, in which a mass consisting of media and workpieces is flowed in the barrel of the machine for abrasive finishing of the workpieces and in which air suction is used to remove dust resulting from the finishing operation and to cool the barrel and the mass. The mass is flowed by rotation of the barrel by a motor or through the vibration of the barrel by a driving mechanism. Air inlets and outlets are provided in the barrel. An air suction device draws air through the barrel and around the workpieces and media during the finishing operation. The drawn out air picks up dust and media particles resulting from the abrasive finishing operation and cools the media and the barrel.
