The turntable has resting surfaces formed by an inner ring (11) and at least one outer ring (12) concentric with it. The inner ring is driven independently of the one or more outer rings. There may be a hole grid (18) in the surface of the inner and/or outer rings, which may also have clamping devices for the workpieces. The inner ring and/or outer ring or rings may be divided into several sectors (17) separated by wall elements.
