Abstract:
A concentric machining device for machining the outer circumferential surface of a cylindrical body having an inner diameter and an outer diameter with respect to the center of the inner diameter, comprising:mounting means for mounting the cylindrical body therein;rotating means for installing the mounting means therein and rotating the mounting means and the cylindrical body according to a rotation control signal;photographing means for photographing a cross-section of the cylindrical body;controlling means for generating the rotation control signal to rotate the rotating means at a predetermined angle when the cylindrical body is mounted, calculating an eccentricity being the difference between the inner diameter center of the cylindrical body and a rotation center of the rotating means from information about the photographed cross-section received from the photographing means, and generating a machining control signal corresponding to the eccentricity;transferring means for transferring the machining control signal; andadjusting means for adjusting a position of the cylindrical body according to the machining control signal received from the transferring means so that the inner diameter center of the cylindrical body is identical with the rotation center of the rotating means,whereby the center of the outer diameter is identical with the center of the inner diameter.
