I recently bought a 30.5" rotary table at an auction, it is huge, weighs in at 4,130 lbs. Here's my question, how does the fanuc drive actually turn the table? There isn't a visible link between the drive motor and the rotary table. There are air lines and three steel lines under the table leading to the center point of rotation, but no drive shaft, worm gears or other visible means of revolving/indexing the table. There is an elaborate system of pressure regulators and several lines going to several areas.
