Grinding Machine

A double radius is ground on a workpiece by rocking it inside a cylindrical grinding cavity.

An abrasive-lined drum having an inside radius Rl is rotated on an axis. A first workpiece contour with a radius R1 is formed by placing the end of the workpiece in contact with the abrasive. If the workpiece is simultaneously rocked about a pivot point A on the drum axis, a second contour with a radius R2 (which equals R1) will result.

If the pivot point is moved off the drum axis away from the end of the workpiece to point B, the radius R2 becomes longer and the second contour will be larger than the first contour. If the pivot point is moved off the axis toward the end of the workpiece to point C, the radius R2 becomes smaller and the second contour will be smaller than the first contour. Other second contours are possible by moving the point along the axis, for example to point D.
