QLC, 3-Jaw, Wedge Style Power Chuck
The Forkardt QLC Wedge Style Power Chuck provides a high precision universal application power chuck that is suited for practically all turning applications.
The higher clamping force and higher precision than a standard wedge style power chuck make the QLC especially suited for heavy duty machining of disk and bar components as well as high precision finish machining of easily deformed workpieces.
The jaw selections are compatible with the industry standards, making top tooling purchases simpler and more economical.
The lighter weight design allows for faster speeds which, combined with the optional quick change jaw system make the QLC an excellent choice for companies interested in decreasing machining time and saving energy and wear and tear on the spindle.
Using different type of base-jaw to equip QLC to your special application.
