Apparatus for polishing a spherical surface |
摘要 |
An apparatus for polishing spherical surfaces of workpieces includes a polishing device rotating on a shaft thereof while holding a polishing tool at an end of the shaft. A pivoting device pivots the polishing device around a polishing position of the tool. A plurality of workpiece holders each hold a workpiece at an end thereof so that one of the workpieces is opposed to the tool. Workpiece holder-holding devices hold the workpiece holders so as to be rotatably and vertically movably. A workpiece holder-pressing device presses at least one of the workpiece holders held by the workpiece holder-holding device against the tool. A rotary table rotates while holding the workpiece holders and the workpiece holder-holding devices, thus placing at least one of the workpiece holders at a workpiece replacing position when the other of the workpiece holders is placed at the polishing position of the polishing device.
