Is it possible to measure eccentricity of the roll, i.e. the axis not in the centre of the roll?
No- because the carriage is running along the roll surface with no reference to the axis or the journals. By far the best way of measuring eccentricity is to mount a measuring probe radial to the roll surface from a suitable mounting point on the grinding machine. (If required the CADNO measuring probe can be removed from the electronic calliper assembly and used in this way. In calibration mode the movement of the tip of the gauging probe is displayed in micron on the microcomputer based module.
