摘要： There is provided a conductive grinding wheel 10 rotating centering on a vertical shaft center and including a horizontal working surface 10a, and the grinding wheel comprises a conductive base member 11 formed of an integrally molded flat plate, and a plurality of fan-shaped segments 12 detachably attached to the base member to entirely constitute the annular working surface. Each segment comprises a base metal 12a directly attached to the base member and a grinding wheel part 12b formed on the surface of the base metal. Moreover, the grinding wheel part comprises a recessed groove 14 for partitioning the working surface into a plurality of working areas 13, and an electrolytic fluid supply hole 15 for directly supplying the electrolytic fluid to the respective working areas, so that the electrolytic fluid is supplied to the respective electrolytic fluid supply holes through the base member.

摘要： A work mounting apparatus has a head drum rotated in one direction, work heads arranged on the outer periphery of the drum, each work head including a suction nozzle projecting from the work head toward a circular travel path, for moving along the travel path while keeping a fixed orientation and repeating a cycloidal motion during rotation of the head drum, a work feeder arranged on the travel path, and a movable table arranged on the travel path at a distance from the work feeder, for receiving thereon a printed board, wherein the suction nozzle of each work head sucks up a work from the work feeder and releases the sucked work at a desired release position on the travel path. The movable table is moved along a line intersecting the travel path, whereby a target point on the printed board, at which the work is to be mounted, is brought to the release position on the travel path, in cooperation with cycle control of the cycloidal motion of the work head.
