Abstract:
A table rotation device includes a bearing assembly, a table support member, a support block, and a cooling block. The bearing assembly includes a fixed ring, a movable ring, and rolling elements provided between the fixed ring and the movable. The movable ring is rotatable about the rotation axis. The table support member is connected to the movable ring so as to fix a position of the table support member relative to a position of the movable ring. The support block is connected to the fixed ring so as to fix a position of the support block relative to a position of the fixed ring. The cooling block is connected to at least one of the fixed ring and the support block such that the cooling block is in contact with both the fixed ring and the support block. The cooling block provides a cooling passage.
