CNC 무심 연삭기의 유정압스핀들 진동특성에 관한 연구

Ultra Precision centerless grinder the ferrules determine the transmission efficiency of the information. They are precision component which high precision is desired. We are using a ZrO₂ to the material of the ferrule. Consequently the processing of goods depend wholly on a grinding task. Especially a grinding processing justice is most important to making the quality. The precision to be desired at an out-diameter processing of the ferrules are greater a part sub-micron. Strict precision have been desired especially in a roundness, surface-roughness, cylindricity management of matters. Such precision depends on the characteristic of a processing mechanism. We depend greatly on the precision and stiffness of a grinding spindle. We can be satisfied a ferrule requirement precision in this paper. Ultra Precision centerless grinder A stiffness rotation accuracy of the spindle accomplished a vibration characteristic assessment.
