    • Apparatus for polishing a spherical work surface comprising a resilient polishing pad formed on a flat rotatable base and including at least one layer of resilient material sandwiched between a flexible abrasive sheet and the base, a workpiece holder for urging a workpiece against the polishing pad with a uniform pressure while simultaneously rotating the workpiece at a uniform rotational speed, an oscillatory motion generator for causing the holder to move randomly over the surface of the polishing pad, the holder and the oscillatory motion generator. The durometer of the resilient layer, the flexibility of the abrasive sheet and the size of the spherical work surface are all matched so that the abrasive surface uniformly conforms to the shape of the work surface to achieve a substantially uniform polishing thereof.
    • 用于抛光球形工作表面的装置,包括形成在平坦可旋转底座上的弹性抛光垫,并且包括夹在柔性研磨片和基座之间的至少一层弹性材料,工件保持器,用于将工件推向抛光垫, 均匀的压力,同时以均匀的转速旋转工件;振荡运动发生器,用于使保持件随机移动到抛光垫,保持器和摆动运动发生器的表面上。 弹性层的硬度计,研磨片的柔性和球形工作表面的尺寸都相匹配,使得研磨表面均匀地符合工作表面的形状,以实现其基本均匀的抛光。
