    摘要： A work carrier is disclosed in which a pair of carriers are rotatably mounted on either side of a swing arm assembly, each carrier adapted to receive a workpiece which is held therein for grinding by a three-point rest support engaging the reverse side of the workpiece surface to be ground, and by a series of peripheral locaters to accurately position the workpiece while minimizing mechanical distortion incidental to such positioning. Both of the carriers are rotated in such a position that the workpieces remain in continuous contact with the grinding discs during grinding with this rotation being accomplished by a fluid motor and chain drive arrangement, the chain drive being located in internal openings in a member included in the swing arm assembly so as to be totally enclosed and protected from the abrasive grit. The swing arm assembly includes an upper swing arm assembly detachably mounted to a pivot housing adapted to be pivoted about a pivot shaft to swing the carriers into position between the discs. The upper swing arm assembly extends at an angle to the pivot housing so that the rotary drive motor may be located well above the coolant bin, and the detachable mounting allows ready replacement of the swing arm assembly without the necessity of removing the pivot housing. A specific work ejector mechanism is also described consisting of a pair of plungers carried in a central portion of the work carrier and adapted to be axially extended by a power cylinder and ejector mechanism so as to push the workpieces from the work carrier after grinding.

    摘要： A DEVICE FOR SUPPORTING A WORKPIECE BETWEEN A HEAD STOCK CENTER AND A TAIL STOCK CENTER COMPRISES AN ELECTRIC GUAGE RESPONSIVE TO THE CUTTING RESISTANCE OF THE WORKPIECE, A CONTROL CIRCUIT TO CONVERT THE OUTPUT OF THE ELECTRIC GUAGE INTO AN ELECTRICAL OUPUT, MEANS TO APPLY FLUID PRESSURE TO THE TAIL STOCK CENTER AND AN ELECTRO-FLUID PRESSURE CONVERTING MEANS RESPONSIVE TO THE OUTPUT FROM THE CONTROL CIRCUIT TO VARY THE FLUID PRESSURE APPLIED TO THE TAIL STOCK CENTER IN ACCORDANCE WITH THE VARIATION IN THE CUTTING RESISTANCE WHEREBY TO APPLY HOLDING PRESSURE COMMENSURATE WITH THE CUTTING RESISTANCE TO THE WORKPIECE BY THE TAIL STOCK CENTER.
