Abstract
An apparatus for grinding spherical surfaces of workpieces includes a grinding section having a grindstone rotating mechanism for rotating around an axis of a shaft thereof with a grindstone held at an end of the shaft, a feeding mechanism for feeding the grindstone rotating mechanism toward the workpiece in a direction along the shaft, and a fixing mechanism for holding the grindstone rotating mechanism and the feeding mechanism and determining an angle 1 inclination of the short of the grindstone rotating mechanism with respect to the workpiece. A plurality of workpiece holding mechanisms are provided for holding the workpieces at ends of shafts thereof, the workpiece held by at least one of the workpiece holding mechanisms being opposed to the grindstone. A workpiece rotating mechanism is provided for rotating the workpiece holding mechanism which holds the workpiece opposed to the grindstone. A workpiece positioning section is provided for holding the workpiece holding mechanisms and being rotated and stopped so that an unground workpiece held by at least one of the workpiece holding mechanisms is placed at a workpiece replacing position when a ground workpiece held by the othe…
