<p>Point-grinding apparatus (10) comprising frame means (12), workpiece transport means (20) operably mounted on the frame means for transporting a plurality of elongated workpieces therealong, workpiece support means (27) disposed adjacent the transport means for supporting the elongated workpieces in contact with the transport means and grinding means (14) including an asymmetrical concave grinding surface disposed adjacent the transport means to engage workpieces supported by the workpiece supporting means, the asymmetrical concave grinding surface being configured and dimensioned such that a surface area of each workpiece which contacts the grinding surface varies relative to the position of the workpiece with respect to the grinding surface. A method for grinding needle points is also provided including the steps of, providing a rotating grinding wheel having an asymmetrical concave grinding surface and feeding at least one workpiece to a first position such that each at least one workpiece is advanced along the grinding surface. Preferably, the method further comprises the step of removing the workpiece from between the transport wheel and the workpiece support means at a second position thereof. <IMAGE></p> |
