Fully automatable, tool-free jaw quick-change

It takes a maximum of 60 seconds until a conventional 3-jaw chuck with SCHUNK RAPIDO clamping inserts is retooled. For granting such a speedy jaw change, the RAPIDO clamping inserts must be put onto the base or intermediate jaws and moved backwards until they snap in. The exchange can be done manually or in case of lathe chucks with integrated base jaws, it can be done fully automatic with a robot.

A locking mechanism always ensures safe hold of the snapped in clamping inserts, even if they are not clamped. The system can be used, no matter if the spindle is horizontally or vertically positioned. Due to the high-precision quick-change interface, SCHUNK RAPIDO achieves an appropriate repeat accuracy of <0.02 mm for many types of finish machining. The quick-change system can be used for I.D. and O.D. clamping. In order to ensure the required flexibility, SCHUNK has launched a concept of jaw blanks consisting of soft clamping inserts of different heights. What is more: due to this concept, clamping inserts with claw contour, application-specific, or weight-reduced variants can be manufactured as a modified standard version within a very short time, or the users can machine them by themselves. On request, the RAPIDO clamping inserts can be individually equipped with an RFID chip, QR code, or an individual labeling. Other variants are available as a special design.

Fully incorporated or as a retrofit kit
SCHUNK RAPIDO is available in two variants: fully incorporated in the SCHUNK power lathe chuck. In this case, the lathe chuck will be equipped with the RAPIDO base jaw before leaving SCHUNK. Unlocking of the clamping inserts can be done manually or fully automatic. In case of the second version, the RAPIDO can be simply retrofitted onto already existing lathe chucks by putting a RAPIDO intermediate jaw onto the existing base jaw, and by replacing the respective RAPIDO clamping insert. This version can be exchanged manually by using a pin. If the intermediate jaw is removed, chuck jaws with conventional interfaces can be further used.
