PURPOSE:To provide a pinion cutter grinding method in which a pinion cutter having the long precision assurance range can be easisy manufactured. CONSTITUTION:As for a grinding method for grinding a pinion cutter 1 for a generating gear by the simultaneous three-axis control for a grinding wheel, the approximate straight line which passes through two points (a) and (b) on both the end sides on a theoretical curved line for setting the chamfer quantity of the generating gear constant is obtained, and the middle point (c) between two points (a) and (b) is obtained on the theoretical curved line, and the approximate arc AL passing three points (a), (b), and (c) is obtained. The grinding wheel 2 is shifted along the approximate arc AL, and the grinding wheel 2 is corrected in the grinding wheel axis direction according to the deflection in the radial direction of the pinion cutter between the approximate arc AL and the approximate straight line SL. |
