Abstract
A gear grinding machine comprises: a moving mechanism rotatably mounted with a threaded grinding wheel, and arranged to move the threaded grinding wheel along directions of X, Z, and Y, and to turn the threaded grinding wheel in a Y-Z plane; an NC device for controlling the position of the threaded grinding wheel; and a rotary dressing device having a dressing tool which contacts the flanks of the threads of the threaded grinding wheel, while rotationally driven, to perform dressing. The NC device numerically controls the moving mechanism so as to adjust the positions in the directions of X and Z, and the turning position in the Y-Z plane of the threaded grinding wheel, while keeping contact of the dressing tool with the flanks of the threads of the threaded grinding wheel, in order to modify the wheel pressure angle of the threaded grinding wheel.
