ABSTRACT:
A track slider grinder grinds a track slider of ferrite having a tracing surface and an integral C-shaped core positioned on one side of the tracing surface and including a coil support portion in the form of a quadrangular prism having a central axis. The track slider grinder includes a holder for supporting the track slider for rotation about the central axis of the coil support portion, a rotational drive source for angularly displacing said holder through a prescribed angle, a grinding tool for grinding an edge of the coil support portion of the core into a duller surface, a three-dimensional guide drive mechanism for relatively moving said grinding tool and said holder in X-, Y-, and Z-axis directions, and a numerical control unit for controlling said three-dimensional guide drive mechanism to position the track slider and said grinding tool relatively to each other and for enabling said grinding tool to grind the edge of the coil support portion of the core while relatively moving said grinding tool and the core in the direction of the central axis of the core. The grinding tool may comprise a rod-shaped rotatable sander or a sand blasting nozzle.
