Special toolholding solutions are applied for particular customer solutions. There is one toolholder that can be applied for most of the applications—a hydraulic toolholder.
A hydraulic toolholder uses a different way of clamping the cutting tool compared to systems of conventional toolholders. Introduction of force is done via a screw (with a screw, a piston and sealing).

By actuating (turning) the screw, an even hydraulic pressure is generated inside the toolholder. This pressure is transmitted via a steel expansion sleeve, which clamps the tool.
With this clamping system, best run-out accuracy and a repeatability of less than 0.003 mm (0.00012”) are achieved. As the cutting tool is held in a hydraulic chamber, the toolholder offers superior damping effects, due to the oil in the holder. The user gets a higher surface quality of the workpiece and higher up-times of the toolholder as small eruptions of material, as a result of vibrations of the cutter, are avoided.

These toolholders are not only maintenance-free and resistant against dirt, but they also are easy to use and offer a safe clamping of the cutting tool.
