Ringspann Clamping System Features Universal Seating Body

Ringspann’s BKDW clamp series consists of 10 sizes of taper collet flange mandrels with identical connectors, all characterized by a running accuracy of ≤ 0.01 mm. Distinguishing features include the clamping range of the taper collet, the change in its diameter, as well as the maximum transmissible torque and the maximum actuating force. When used with the FUSR-series spring force actuators, the BKDW series covers a clamping range of 11.9 to 132 mm and offers flange mandrels with maximum actuating forces between 2,300 and 3,840 N, which can transmit torques of 11 to 25 Nm. The diameter expansion of the taper collet is a maximum of 1.2 mm.

Each flange mandrel from the BKDW series consists of a taper collet with a draw bolt and a universal seating body that which connects it to the spring force actuator FUSR or to the intermediate flange of the balancing machine. It is set into action via the draw bolt, which is connected to the power clamping device (of the spring force actuator or the machine). During clamping, the taper collet is pulled over the taper of the seating body and expands radially. In this way, the workpiece is securely centered, pressed against the backstop surface and aligned flat. Upon request, Ringspann also supplies the functional unit of a taper collet and draw bolt with pre-centering for use on fully automated systems with integrated handling systems.

All taper collet flange mandrels of the BKDW series are suitable for balancing both thin-walled and solid workpieces. The maximum insertion depths range from 31.9 to 147.55 mm. For the calibration of the clamping system consisting of the FUSR spring force actuator (or intermediate flange) and flange mandrel BKDW, the user can receive an optional control balancing ring designed for the respective clamping diameter.
