Stationary 2-jaw chuck in the cam production. Wedge hook principle for the transmission of high clamping forces ensures a firm fit of the workpiece during machining. The well-known QLC jaw profile for high repeatability. Low clearance in the guide and plenty of guide surface by wave profile ensure the good distribution of high forces. Continuous lubrication via the stroke movement and forced circulation of the lubricant from the integrated lubricant reservoir ensure a low-maintenance long life cycle of the base jaws and the guides.
