With the centrically compensating ROTA-ML flex 2+2, SCHUNK has had a low-maintenance manual chuck in its portfolio since 2020, with which almost all workpiece geometries - whether round, cubic or geometrically irregular - can be clamped precisely and efficiently on mill/turn centers. Its patented drive concept features a particularly large compensation stroke of 12 mm per jaw. With the redesign, SCHUNK has once again significantly improved the manual chuck.
With a design facelift from the 500 millimeter diameter size upwards, the toolholding and workholding expert has reduced the chuck height by up to 30 percent. This also reduces the feed weight by up to 40 percent. The lower mass not only enables faster table speeds, but also the reliable processing of even larger and heavier workpieces. This increases the variety of possible applications with just one chuck and boosts efficiency in machining processes.
The revised base plate of the chuck also ensures greater flexibility. The chucks can therefore be quickly and easily mounted on almost any machine table.
The special seals on the guideways have been retained. They prevent grease from being rinsed out and the clamping force from being gradually lost. This guarantees precise chuck function, even with low clamping forces A patented sealing concept protects the drive kinematics from dust and chips, thus ensuring greater process reliability and longer maintenance intervals. In addition, an indicator pin on each jaw signals the optimum clamping range for secure workpiece clamping.
SCHUNK offers the flexible manual chuck in eight sizes with diameters ranging from 260 to 1200 mm.
