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.
Optimally matched components
A planetary threaded drive, a superimposed gear unit and a servomotor – with this trio HAINBUCH, the Marbach-based clamping device manufacturer, wants to revolutionize machine tools. The technology is both simple and ingenious: The spindle transfers the drive of the planetary threaded nut directly via the superimposed gear unit. An »emergency stop situation« or a »reversing operation« can be realized without complex adjustment technology. The superimposed gear unit is responsible for the tension stroke or the clamping force adjustment and the servomotor is only used for a clamping movement.
Process-oriented clamping force, less energy consumption
The hydraulics, which are oil-intensive and maintenance-intensive, are without a doubt responsible for the lion's share of total energy consumption. Obviously this is an aspect of hydraulic clamping cylinders that is especially pronounced and is reflected in high leakage rates, large aggregates, and a correspondingly high consumption of energy. In addition the power losses for hydraulic rotary feeds with increasing through-bores are extremely high. This is precisely the point that HAINBUCH addresses; HAINBUCH has set itself the difficult task of substituting the hydraulics and thus producing a totally new, energy-efficient generation of hollow clamping cylinders.
