Device which has a high precision and a ultra-micro structure is highly important in the product of the digital-network. In the field of optical device, a micro V-groove which the size of width is micron meter size is required. The authors had developed a micro grinding method for the micro V-grooving that the tool is trued to the sharpened cone shape by the micro EDM process on the same machine. We describe the application this method to make V-groove on the three dimensional surface mold which is the electroless nickel plated for an aspherical lens and show some results of examples.
