Edge sensor 827
For accurate positioning or orientation of work spindle in relation to workpiece.
The sensor is inserted in the work spindle and is applied under the rotation of the spindle nose towards the scribed line, edge or surface on the workpiece from which the measuring is to be made. The sensors fluttering contact point is by this means steered towards the starting edge and a better centering of the contact point is obtained as the starting edge comes towards the spindle centre. On completion of the centering the contact point makes a deflection sideways. The procedure is repeated twice as a safety check.
