    摘要： 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.

    摘要： A space-saving centerless grinding machine having high operability is obtained by devising the configuration of component units around the basic configuration of the machine. A dressing means for performing a dressing process for a grinding wheel and a regulating wheel comprises a single dressing unit. The dressing unit is located at a lower position between the grinding wheel and the regulating wheel, and thus eliminates the need for right and left dresser spaces for grinding wheels that have most seriously affected the breadthwise dimension of a conventional centerless grinding machine, leading to space saving and a considerable reduction in the breadthwise dimension of the centerless grinding machine.

    摘要： A machine which may be used to either check or to machine the profile of an orbiting star gear for a gerotor type of fluid motor or pump is disclosed. The profile of a star gear is traced due to the interaction of a slide that carries a sensor, or a machining tool, in a back and forth direction toward and away from the star gear and in a second direction transverse to this back and forth direction with respect to a frame member. The slide is driven by an eccentric disc, at a rate which is determined in accordance with the number of teeth on the specific star gear in question. The combined motion of the star gear and the two slides causes the sensor, or the machining tool, to trace out the profile of the desired star gear for the purpose of either checking its profile, or of machining a new gear. A spring member is connected to the frame member to allow the frame member to move in a transverse direction but without rotation.
