    摘要： A finishing grindstone member 20 is fixed to a spindle 10 by a bolt. In the spindle 10, there is formed a tool mounting portion 25 into which a rough grindstone member can be mounted. Into the tool mounting portion 25, there can be mounted not only the rough grindstone member but also a cover member 36. After a silicone wafer is roughly ground using the rough grindstone member, when finish grinding the silicone wafer using the finishing grindstone member 20, the cover member 36 is mounted onto the tool mounting portion 25 to thereby prevent the tool mounting portion 25 from being soiled.

    摘要： A spindle 23 of a grinding wheel 28 is rotatively borne by a bench 22 for the grinding wheel through hydrostatic thrust bearings 26 and 27. A pressure regulator 38 for regulating the pressure which must be supplied to at least either of supply ports 26a and 27a opposite to each other in the direction of the axial line of the spindle 23 in the hydrostatic thrust bearings 26 and 27 is provided. The pressure regulator 38 has a changing member for changing a passage for choking the fluid and the length of the choking passage.
