ABSTRACT:
In a polishing machine for simultaneous double-sided polishing of workpieces between upper and lower polish tables, the upper polish table has a hollow center telescopically receiving in a drive hub supported from below. The drive hub is slotted and the upper polish plate has drive latches received in the slots. Lateral dislocations of the upper polish plate with respect to the drive hub are limited by providing stops on the drive latches which engage the outer surface of the drive hub. Additionally, the upper polish plate is suspended by a lifting rod from a double-ended main lifting cylinder.
