Clamping method for workpieces used for the production of compressor or turbine wheels

A method for producing a plurality of compressor or turbine wheels, in a milling machine tool, the method comprising the steps of:

• providing a machine tool, in which the contour of flow-conducting sections of the compressor or turbine wheel is machined using a rotating milling tool on the workpiece;
• accommodating the workpiece in a workpiece support and fastening the workpiece relative thereto for the production process;
• in a positioning step, placing the workpiece, by means of a positioning aid, in a certain position within the workpiece support, said position being used for a subsequent production process and being at least radially predetermined relative to a longitudinal axis of the workpiece support;
• and
• fastening the workpiece within the machine tool in an axial direction relative to the workpiece support in a clamping step that differs from the positioning step wherein each of the workpieces provided for manufacturing compressor or turbine wheels is arranged in the machine tool and subsequently milled.

A compressor wheel or turbine wheel clamping device for arrangement of a workpiece provided for producing a compressor wheel or turbine wheel in a milling machine tool, which comprises:

• a workpiece support which can be moved in and out of the milling machine tool and on which the workpiece can be arranged in a manner suitable for milling;
• a positioning means by which means a radial alignment of the workpiece can be produced in relation to a longitudinal axis of the workpiece support;
• and
• a tailstock which can be brought to abut against the workpiece for carrying out the milling machining on the workpiece in order to exert an axial clamping force on the workpiece.
