摘要： A grinding machine includes at least a turntable, rotary chuck tables for holding workpieces to be machined, a first grinding device for grinding the workpiece held on the chuck table and a second grinding device for grinding the first-ground workpiece held on the chuck table. The first grinding device comprises at least a first grinding wheel having pieces of grindstone set so as to define together a first grinding plane, and a first spindle fixed to the first grinding wheel. Likewise, the second grinding device comprises a second grinding wheel having pieces of grindstone set so as to define together a second grinding plane and a second spindle fixed to the second grinding wheel. The first and second grinding devices are so arranged that the first angle formed between the linear line connecting from the center of rotation of the turntable to the center of rotation of a selected chuck table and the linear line connecting from the center of rotation of the selected chuck table to the center of rotation of the first spindle is equal to the second angle formed between the linear line connecting from the center of rotation of the turntable to the center of rotation of the selected chuck table and the linear line connecting from the center of rotation of the selected chuck table to the center of rotation of the second spindle. This arrangement assures that all finished workpieces have the same thickness.

摘要： Disclosed is an apparatus for grinding spherical objects into an exact spherical shape. The sphere-reshaping apparatus comprises a grinding section equipped with means for grinding spherical objects, an inlet section equipped with means for feeding spherical objects to the grinding section and an outlet section equipped with means for taking out reshaped spherical objects from the grinding section. The inlet section, grinding section and outlet section communicate by transporting means. The transporting means comprises an endless carrier belt having a series of apertures made for accepting spherical objects and a drive for driving the endless carrier belt. In the grinding section an endless grinding belt runs parallel with the endless carrier belt in same or counter direction relative to the endless carrier belt at such a speed that causes spherical objects to rub on the grinding belt. A randomizer moves back and forth across the carrier and grinding belts to sandwich spherical objects between the randomizer and the grinding belt, thereby assuring deviation-free grinding of spherical objects.
摘要翻译：公开了一种用于将球形物体研磨成精确球形的装置。球形整形装置包括配备有用于研磨球形物体的装置的研磨部分，具有用于将球形物体馈送到研磨部分的装置的入口部分和装备有用于从研磨部分取出重新定形的球形物体的装置的出口部分。入口部分，研磨部分和出口部分通过输送装置进行连通。传送装置包括具有一系列用于接收球形物体的孔的环形传送带和用于驱动环形传送带的驱动器。在研磨部分中，环形研磨带以相对于环形传送带的相同或相反方向平行于环形传送带延伸，使得球形物体在研磨带上摩擦。随机化器在载体和研磨带之间来回移动以将球形物体夹在随机化器和研磨带之间，从而确保球形物体的无偏磨削。
