    • A turntable with an abrasive cloth mounted thereon and a top ring positioned above the turntable are independently rotatably provided. The top ring holds a workpiece to be polished and presses the workpiece against the abrasive cloth. The turntable and the top ring are rotated to polish the surface of the workpiece to a flat mirror finish on the abrasive cloth. A rotatable brush pressed against the abrasive cloth is rotated about an axis substantially perpendicularly to the plane of the abrasive cloth, and oscillated substantially radially between radially inner and outer positions over the abrasive cloth. A cleaning solution is sprayed from a nozzle onto the abrasive cloth. The turntable has a bank along an outer circumferential edge thereof for preventing a protective solution, which is supplied to the abrasive cloth to keep the abrasive cloth wet and prevent it, from flowing off the turntable when the turntable is stationary.
    • 具有安装在其上的研磨布的转盘和位于转台上方的顶环可独立地可旋转地设置。 顶环保持要抛光的工件,并将工件压在研磨布上。 转盘和顶环旋转以将工件的表面抛光到研磨布上的平整镜面。 压在研磨布上的可旋转刷子围绕基本上垂直于研磨布平面的轴线旋转,并且在磨料布的径向内部和外部位置之间基本径向摆动。 将清洁溶液从喷嘴喷射到研磨布上。 转台沿其外圆周边缘具有一个堤,用于防止当转盘静止时供给磨料以保持磨料湿润并防止磨损的保护液从转盘流出。
