GRINDING DEVICE Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: device represents two grinding wheels having bodies positioned on one faceplate. Bodies are made of magnetostrictive material with negative and positive magnetostriction, respectively. Coarse- and fine-grained abrasive layers with continuous operating surface are applied on the bodies, respectively. For performance of successive roughing and finishing magnetic system enlarges diameter of one body and reduces diameter of other body, as a result of which continuous process of cutting is ensured. EFFECT: improved quality of machining. 2 dwg
