If the point of the center is not in perfect alignment with the shaft, or if the center mark on the part is not dead-on, the part will "run out" (vibrate or wobble), making precise machining impossible. An adjustable live center allows you to precisely position the center. The center is attached to one plate, while the shaft is part of another. Two slightly oversize holes in one side allow adjustment screws to be loosened, the center located and then locked down where you want it. In this manner, highly accurate centering can be achieved. If the ultimate in accuracy is your goal, the adjustable live center will help you achieve it. The standard Adjustable Live Center is P/N 1201. It has a sharp 60° point to fit into a center drilled hole in the part to be supported. The P/N 1205 live center is much larger and will support a part with a larger center hole or tubing from about 5/16" ID up to 1-3/4" ID.
