QLC-AG, 3-Jaw, Compensating, Wedge Style Power Chuck
The Forkardt QLC-AG power chuck is specially designed for machining of shafts. The QLC-AG power chuck compensates to clamp off-center parts with high precision at high clamping force. A pull back action provides for improved part location on the center, and the centers are easily interchangeable and finely adjustable. The QLC-AG has integrated axial stroke limitation to ensure that over stroke of the cylinder does not occur. This power chuck is also designed to provide simple change over self centering for general clamping work. The QLC-AG is available in sizes 200 mm (8“) to 400 mm (15“).
