Abstract

A method for machining at least one portion of a surface of a component for a vehicle, which is painted with a layer of clear coat of a given first layer thickness. The component is situated in an inner space of a blasting chamber. An opening of at least one conveying device for a blasting material emerges into the inner space. The inner space of the blasting chamber and the component are placed entirely under a partial vacuum. Blasting material in a carrier air flow generated by the partial vacuum is supplied through the opening of the conveying device to the inner space. The portion of the surface being machined and the opening of the conveying device are moved relative to each other. The blasting material is shot from the opening of the conveying device onto the portion of the surface being machined.
