A processing machine for a component in the form of a turbine blade, an impeller or a blisk, comprising the following features: two opposing handling units (24, 28) having holding elements for a component positioned in between; a milling head for machining the component; a movable processing unit having a tool head receiving unit which is designed such that the milling head is dockable to the tool head receiving unit, said movable processing unit comprising the following elements: an Y basic carriage unit which is displaceable with respect to a machine base frame along an Y axis extending in upward and downward directions, a Z basic carriage unit which is displaceable with respect to the Y basic carriage unit along a Z axis extending in forward and rearward directions, and wherein the tool head receiving unit is rotatably supported on the Z basic carriage unit and is designed to be rotatable about a B axis which is arranged parallel to the Y axis of the Y basic carriage unit; characterized in that the processing machine is intended for restoring a component in the form of a used turbine blade, a used impeller or a used blisk; that the processing unit comprises a laser welding head for laser deposition welding on the component; that the movable processing unit with the tool-head receiving unit is designed such that the laser welding head for laser deposition welding on the component is dockable to the tool head receiving unit such that material can be applied to locations of the component at which there is material missing; and that the processing unit comprises furthermore a material and laser beam supply unit (50, 52) for the laser welding head, which includes a laser beam source and an optical guide for the laser beam as well as a material supply and which is mounted on the rotatable tool head receiving unit or on the Z basic carriage unit and is designed such that, when the laser welding head is docked to the tool head receiving unit, it provides the laser welding head with the laser beam for laser deposition welding and with the powdered material. two opposing handling units (24, 28) having holding elements for a component positioned in between;
