ABSTRACT:
A polishing spindle is provided for use in a polishing device which includes a hollow spline shaft, and a polishing tool having a polishing member which defines a first bag-like elastic member and is attached in an airtight manner to a forward end of the hollow spline shaft. A device supplies a compressive fluid to the other end of the hollow spline shaft through a rotary joint, another device rotatably supports a nut which engages the hollow spline shaft, and a further device rotates the hollow spline shaft. A still further device is provided for displacing the hollow spline shaft in an axial direction. A second elastic member is provided along the axial direction of the hollow spline shaft so as to depress the polishing member against a workpiece under a constant pressure.
