Accurate Conicoids By A Grinding Process

The section of a conicoid used for X-ray reflection optics has a slow change of curvature; i.e. the difference between a straight generator and the actual generator is quite small. A grinding machine has been built to generate a cone with a means of correcting from a straight line to the curve required. This correction is produced by means of a 20 to 1 lever system from a template with a magnified contour.
