We Solve Your Gripping Problems Extraordinary fields of application need extraordinary solutions. Owing to their shape, size, weight or other properties, many work pieces cannot be optimally clamped and machined with standard chucks. Our engineers are constantly on the lookout for these challenges. Many of our applied solutions become standard products. One example would be the development of the indexing chuck, which has hydraulic centrifugal force compensation that makes it ideal for fittings manufacturers. Another is the equalizing counter-centrifugal ball chuck, which is ideal for...

Wedge Style Power Chuck The QLC line of Wedge Hook Style Power Chucks provides a combination of innovative design, high quality materials, and advanced manufacturing techniques. All Forkardt products are developed and produced in accordance with the requirements of ISO 9001-2000. The QLK offers all of the features of the QLC, without the centrifugal force compensation. QLC power chucks utilize a wedge hook mechanism. Each of the chuck models available in the QLC power chuck line feature centrifugal force compensation, allowing for higher speeds, higher gripping forces, improved accuracy,...

Wedge Style Power Chuck Application Examples With the options of closed center, large thru-hole, long stroke, counter centrifugal, shaft balancing, and low maintenance the QLC line of power chucks can be used for almost any application. Below are some examples of applications where the QLC was used, with the addition of engineered top tooling and fixturing. QLC-KT with Rotor In this example, top jaws and fixtures were designed to hold the OD of the rotor. The closed center KT chuck was used so that chips did not enter the chuck as the ID of the rotor was machined. In this example, a QLC...

The Forkardt QLC wedge style power chuck provides a high precision, universal application chuck that is suited for practically all turning applications. The lightweight design allows for faster speeds, which combined with the optional quick change jaw system makes the QLC an excellent choice for decreasing machine cycle times while saving energy and spindle wear. The QLC features a higher clamping force and higher precision than a standard wedge style power chuck, making it especially suited for heavy duty machining of disk and bar components as well as high precision finish machining of...
