Title:
How to reduce the degree of eccentricity of the inside over the external surface of the hollow work piece stretched so that rotation in a machine tool was possible
Document Type and Number:
Japanese Patent JP6008207
Kind Code:
B2
Abstract:
The invention relates a method for reducing the eccentricity of the inner and outer surface (7, 9) of a hollow workpiece (i), for example a hollow shaft, rotatably clamped in machine tool (2), in which in one clamping a plurality of measurement data depending on the contour of the inner surface (7) of the hollow workpiece (i) are recorded, for example with the aid of ultrasound, using the recorded measurement data a desired surface (13) is calculated for at least a part of the outer surface (9), which has a reduced eccentricity with respect to the inner surface (7) and in a further step the rotating workpiece (i) is at least partially machined at the outer surface (9) thereof according to the desired surface (13).
