First, a 0.5 mm high tuning ring is inserted between the quick-change pallet module and the fixture membrane, then the exact work piece geometry is milled according to the blank of the fixture's clamping surface. Once prepared, the work pieces can be inserted within seconds, and the complete circumference is clamped by locking the VERO-S module and the fixture membrane is specifically deformed. Since the whole process is carried out within the elastic range of aluminium, the clamping operation can be repeated several thousand times. In contrast to conventional clamping blocks, the clamping force of this clamping type is carried out at the circumference of the whole work piece contour and not just along an axis. The resulting force-fit clamping ensures an even, gentle, yet very secure clamping. The membrane is actuated via an SPC quick-change clamping pin, and connects it with the pneumatically actuated quick-change pallet module. Due to the clamping depth of only a few millimetres, the work piece is fully accessible from five sides. The fixture membrane can be located on the quick-change pallet module at a repeat accuracy of less than 0.01 mm. The use of an additional clamping unit is unnecessary. If required, it can be milled off several times, and different work piece geometry can be used. The clamping unit is suitable for light machining of various materials and work piece contours for the second set-up. The maximum work piece diameter amounts to 120 mm.
