Hydraulic Compensation
With this range of clamping chucks and mandrels we can
offer you real leaders for high precision tool clamping. Thanks to the integrated hydraulic compensation, parts with extremely thin section that are prone to distortion can be clamped safely and with practically no deformation using these clamping tools - even with high chip production.
The Hydraulic Compensation Principle
is based on separating the centring process from the actual clamping process. First of all, the inserted workpiece is sensitively centred mechanically without any deformation. The clamping chucks are each operated separately hydraulically. This means that at the end of the centring process all of the chucks are applying the same force to the workpiece. Only then the requisite clamping force is applied by increasing the hydraulic pressure.
