All conventional clamping devices have the potential to become more efficient, and this is being proven at Schunk’s lathe chuck factory in Mengen, Germany. Here, SCHUNK developed a jaw box, with jaw actuation that is protected against chips and coolant from all sides. The maintenance-free design and the integrated lubrication system minimize wear and assure long service life of the actuation spindle.
The SPK jaw boxes from SCHUNK are available in sizes 180, 220 and 260 mm, which cover about 90 percent of all applications on large horizontal lathes and vertical boring and turning mills. The large jaw stroke of up to 100 mm and the enormous clamping force of up to 75 kN assure safe I.D. and O.D. clamping at low tightening torques. An additional jaw interface at the front makes the unit flexible and allows very low, stable set-ups.
The base jaws of the SPK are equipped with tongue and groove and a standardized jaw connection. Therefore, low-cost standard chuck jaws from the world’s largest program of standard chuck jaws from SCHUNK can be used. For a higher operation and clamping safety, the operator can read off the individual jaw stroke from the scale. With a low height, the SPK provides for space in the machining area. The base body is made of steel and the functional parts are hardened from all sides and assure high precision and a long service life.
