    摘要: A positioning system comprises a feeding mechanism having three or more feeding units disposed in a moving direction of a moving body. Each of the feeding units has first and second moving elements for clamping and unclamping the moving body, feeding the moving body in the moving direction from an initial position to a target position, and returning the moving body to the initial position. A memory device stores preselected phase and amplitude values of the first and second moving elements. A calculating device calculates phase and amplitude command values for the first and second moving elements based on the phase and amplitude values stored in the memory device. An output device outputs driving command values to the first and second moving elements based on the calculation result of the calculating device. A control device controls the feeding units to clamp the moving body by all of the feeding units after the moving body has been moved to the target position.

    摘要: An electrolytic combined processing machine includes a grinding wheel spaced apart from and facing a workpiece, a current switching circuit for switching a coarse grinding to a fine grinding of the workpiece by the grinding wheel, and an infeed switching circuit for switching the infeed speed of an infeed table which allows the grinding wheel to relatively approach the workpiece. The switching operation is based on a measurement result obtained from a size measuring unit which measures a processing amount of the workpiece. During fine grinding, the infeed speed of the grinding wheel is the same as the speed of a passivation coating film generated on the workpiece. Workpieces, particularly of brittle materials, can be processed in a state of less processing distortion with improved surface roughness, flatness and efficiency.

    摘要: A dressing apparatus comprises at least two electrode pieces each having an arcuate inner surface and being arranged around a grinding stone to define a gap therebetween. A gap adjusting mechanism adjusts the gap between the arcuate inner surface of each of the electrodes and the grinding stone and maintains the gap between the arcuate inner surface of each electrode and the grinding stone equal to each other.

    摘要: A grinding machine comprises a grinding member having a thickness greater than 10 mm and an outer contact surface extending in a thickness direction of the grinding member for contacting a surface of a workpiece. The grinding member is supported by a first rotational shaft for rotation about a first rotational axis. A first moving mechanism reciprocates the first rotational shaft along a first displacement axis. The workpiece is supported by a second rotational shaft for rotation about a second rotational axis perpendicular to the first displacement axis and the first rotational axis. A second moving mechanism moves at least one of the workpiece and the grinding member along a second displacement axis to bring the outer contact surface of the grinding member into linear contact with the surface of the workpiece to grind the workpiece. The linear contact between the outer contact surface of the grinding member and the surface of the workpiece has a contact length greater than 10 mm.
