摘要： An electrolytic in-process dressing device 10 is provided with a disk-shaped metal-bonded grindstone 2 with a surface 2a with a circular arc shape with a radius R at its outer periphery and a numerical control device 16. The disk-shaped metal-bonded grindstone 2 rotates around an axis Y, and the grindstone is dressed electrolytically while the device 10 grinds the workpiece 1. The numerical control device 16 is provided with a rotary truing device 12 that rotates around the X axis that orthogonally crosses the axis of rotation Y and trues the circular arc surface 2a, a shape measuring device 14 for measuring the shape of the circular arc surface of the grindstone and the shape of the processed surface of workpiece 1 on the machine, and controls the grindstone numerically in the three directions along the axes X, Y and Z. The numerical control device 16 moves the grindstone in three axial directions and repeats the operations of truing, grinding and measurements on-line. Thus, an axially asymmetrical aspheric mirror with a highly accurate shape and extremely low surface roughness, that can precisely reflect or converge light can be manufactured within a short time with a high accuracy.
