ABSTRACT:
A loader for conveying workpieces from a magazine stack to a clamping spindle where a grinding operation is performed. The loader comprises a reciprocally displaceable carrier assembly having a part holder assembly disposed on the end thereof for laterally receiving and axially releasing small workpieces such as triangular machine tool inserts. The part holder assembly defines a substantially triangular seat having a lateral support surface and being notched out to provide access for the clamping spindle. Precise adjustment of the insert seat is accomplished by means of a cam screw which extends through the part holder assembly to the carrier plate. A relief valve is provided to relax pressure on the part stack during carrier operation to reduce wear due to the sliding of the carrier assembly past the workpiece stack.
