球面的磨削,通常采用成形砂轮,这不仅需要制造复杂的修整工具,而且工件的精度主要取决于砂轮修整的正确性,同时修好的砂轮廓形消耗较快,因而质量难以保证,生产效率也很低。根据圆柱体与球面的相贯线为圆的道理,使旋转的杯形砂轮沿旋转的工件运动,只要两者轴线相交(而不重合)并在同一平面上,则砂轮的端面与内孔(或外圆)的交线在工件上
Spherical grinding, usually using shaped grinding wheel, which not only requires the manufacture of complex dressing tools, and the accuracy of the workpiece depends mainly on the correctness of grinding wheel dressing, while repairing the profile of the wheel consumes faster, so the quality is difficult to guarantee, the production efficiency Very low. According to the principle that the intersection of the cylinder and the sphere is round, the rotating cup-shaped grinding wheel moves along the rotating workpiece, as long as the axes of the two intersect (but not overlap) and are on the same plane, Or cylindrical) intersection on the workpiece
