In addition to ferrite, quartz, etc., it is made of sapphire, zirconium, beryllium oxide, boron compounds, etc., and is well suited for hard and brittle materials, and can be processed in a short time by slicing, screw cutting, polishing, milling, etc. Although it is a grinding machine, it is not possible to minimize the clogging of the grinding wheel that occurs when the workpiece is rotated at high speed and vibrate, and it is not possible to apply stable expansion amplitude in the radial direction. This has significantly hindered the improvement of precision and performance of parts and materials.
