Abstract: An improved device for machining workpieces in a chamber surrounded by a housing. The housing has a hollow space defined by housing walls. A blasting nozzle is positioned in the chamber and is connected by a line to a supply of blasting medium in a container. The chamber is separated by partition walls from the hollow space of the housing. A carrying structure in the hollow space carries the container through a loading opening defined by the housing walls. The loading opening can be closed by a wall. The carrying structure for the blasting medium container is movable between a working position in the housing through the loading opening into a loading position where a filling opening in the medium container is outside the housing.
