ABSTRACT:
Apparatus for grinding tapers and points on elongated needle workpieces having frame means and needle workpiece transport means associated with the frame means for transporting a plurality of the workpieces. The workpiece transport means has a predetermined curvature and workpiece feeder means is mounted adjacent the frame means for feeding workpieces to the workpiece transport means. The grinding means is preferably a grinding wheel disposed adjacent the workpiece transport means to engage workpieces while supported by workpiece supporting means and has a major diameter at a first end and a minor diameter at a second end, the major diameter being greater than the minor diameter. The diameters are connected by a curved grinding surface the diameter of which increases progressively therebetween. The curvature of the grinding wheel in the first third portion between the major and minor diameters is of greater mean curvature than the mean curvature of the corresponding opposed portion of the workpiece transport means. The second third portion of the grinding wheel is of greater mean curvature than the mean curvature of the corresponding opposed portion of the workpiece transport means.
