    • The hard coated abrasive medium is formed by providing a hollow body with abrasive deposit on the outer surface. The buoyancy is provided by the enclosed air space, and the weight is defined by the weight of the body plus the hard plating or the abrasive grit deposited thereon. The density is selected in accordance to the character of the workpiece with which it is to be used in order to optimize the abrading action by interacting with the workpiece in the optimum fashion. In one embodiment, the abrasive grit is bonded to the exterior surface of the abrasive medium in a spiral shape to accelerate the abrading action.

    • A coplanarity inspection fixture for use in determining the coplanarity of a printed wiring assembly with respect to its edge connector. The fixture measures the deviation in parallelism between respective card guides of the printed wiring assembly and the centerline of the edge connector. The fixture includes a frame, a linear bearing block affixed to the frame, a rotational bearing block disposed above the linear bearing block, and a pin slot block fastened to the rotational bearing block. The pin slot block includes a plurality of slots for receiving the rows of pins of the edge connector. Left and right support members are vertically disposed on the frame for guiding and aligning the card guides so that the plurality of rows of connector pins of the connector mate with the slots in the pin slot block. A plurality of clamping jaw assemblies are affixed to the left and right support members that are adjustable to selectively grip a calibration template to calibrate the fixture, and thereafter to calibrate the printed wiring assembly that is to be inspected. Left and right indicators contact the pin slot block adjacent the respective support members along the centerline of the pin slot block, and are zeroed using the calibration template. After calibration, the indicators are used to measure the relative deviation of the centerline of the edge connector with respect to the card guides, which determines the deviation in parallelism between respective card guides and the centerline of the edge connector, whose centerline is designed to be coplanar with the respective centerlines of the card guides.
