  • Grinding machine and method for machining a workpiece
    Patent number: 10207382
    Abstract: The invention concerns a method for machining a workpiece (1) by a grinding machine, comprising the step of rotating and translating the workpiece along a first axis (4) toward the first abrasive wheel; rotating an abrasive wheel (6) around a second axis (61) and translating it along a third axis (62) such that the abrasive wheel grinds a peripheral portion (103) of the workpiece; the abrasive wheel being positioned in a position in translation along the third axis; and wherein the position in translation is determined as a function of a position and of an angular position of the workpiece around the first axis. The invention further related to a grinding machine for carrying out such method.
