Abstract: A self-locking clamping system for hollow shaft adapters is proposed.

Abstract: A coupling device for fluid is proposed which is very simple in construction and requires little installation space, such that it can also be used in stationary or driven tool holders and in other restricted installation situations.

Abstract: A tool holder having at least one sensor and a transmission device for transmitting the data captured by the sensor to a higher-level controller. The power supply to the sensor or the data module can be interrupted without contact when the tool holder is removed from the machining space of a machine tool. This prevents, for example, the power supply from being discharged while the tool holder is in a magazine outside the machine, and, for example, significantly increases the availability and service life of the tool holder before a battery is replaced, and/or before the accumulator and/or charge storage device is recharged.

Abstract: A tool holder which is provided with a plurality of different free jet turbines so that it can be operated, depending on the machining task, with different working rotational speeds and in different operating points.

Abstract: The invention relates to a drive device for clamping and releasing a tool in the tool holding fixture of a tool holder. The drive device according to the invention prevents incorrect operation; said drive device can be operated manually or by a handling robot and can be actively locked to the tool holder.

Abstract: A multi-part adjusting element is proposed, which makes possible a very precise adjustment of a shaft bearing.

Abstract: The invention relates to an interface between a collet holder and a tool adapter, said interface being simple in construction and in which the insertion of a tool adapter is possible in a simple manner even in confined spaces.

Abstract: A drilling-milling device comprising a housing; a drive shaft; a spindle; and a brake. The drive shaft and the spindle being coupled to one another by a gear mechanism, and the brake being coupled to the spindle and a braking torque of the brake being transmitted to the housing.
