According to recent trends, nonspherical shape optical elements is more required by optical instrument is going miniaturization and high-precision. Nonspherical shape optical elements is made by die. So, die is required high-precision. It requires grinding by fine grain whetstone. This experiment purpose making fixed abrasive by fine grain whetstone. This has subject that fine grain whetstone is condensing. The subject can clear by method of PELID. But, this way has new subject. It is repulsion. The method of PELID is using electricity for spraying fine grain whetstone. And it has electricity. It hinder spraying next fine grain whetstone. So, I propose spraying with changing electricity direction. By this way can be laminating fine grain whetstone and making fixed abrasive.
