If you are looking for a hydraulic unit or complex technical control synchronization for the new hollow-spindle clamping cylinder from HAINBUCH, you are looking in vain. This product impresses users with ecological and economical qualities. And technology as it is so often the case with HAINBUCH, looks simple, but is extremely effective. Because the clamping cylinder has no hydraulics, there is no energy expenditure for the hydraulics. It only needs energy for the clamping force adjustment and this is even possible while machining. This is totally practical, process-oriented and obviously adapted to machining and centrifugal forces.

The well-balanced electromechanical actuator trio from HAINBUCH maintains the stroke position, i.e. the tension force, even if there is an abrupt speed change. Neither, a stopping of the spindle, nor a zero crossing of the speed if there is a change in direction, causes a change of the clamping force. Via the servomotor the clamping force can be adapted to the machining and centrifugal forces during the entire machining process. The electromechanical actuator uses energy only in this case, or if there is a change in the stroke position. Consequently it also offers significant energy savings over conventional hydraulic clamping cylinders. Moreover: Where there are no hydraulics, there are no oil changes or a disposal of oil. Ergo: Immense energy savings, lesser load of the machine drive, and at the same time more sensitive clamping force control during the machining process, greater positioning accuracy, and faster actuation of different stroke lengths. Nor is it necessary to move any more than the necessary opening and clamping stroke with the new technology. Employees are working on additional variants - even without through-bore - and these products will follow shortly.
