Detailed description


UNIQUICK® Vario – Stationary screw fastening – precise and reliable

The UNIQUICK® Vario series is available in three sizes, and with its compact and slimline design ideal for adaptation to custom-built machines. Thanks to its special modular construction, the feed stroke is suitable for all sectors requiring stationary screw fastening. An ultra-lightweight and compact version is available for connecting to a robot. The range includes a wide variety of versions, for multiple screw heads, high torques and special infeed strokes, etc. The specific arrangement of the cylinders allows for separate infeed and working strokes.

UNIQUICK® Vario – Series available in three sizes (UVS 50, UVS 75, UVS 100)

UNIQUICK® Best – Electronic current-controlled drives

The UNIQUICK® Best was developed to enable all screw fastening components to be controlled and monitored from a single location, simplifying monitoring processes and integration into larger systems.
UNIQUICK® Best also permits self-forming screw fastenings in cast materials or wood with differing insertion or tightening torques. The drive motor with resolver ensures fast and accurate control of the speed and torque.
The screwdriver is equipped with a particularly smooth-operating spring suspension on the spindle, guaranteeing that the fastening spindle engages securely into the screw’s grip. In addition to high dynamics and speed, this also allows a uniform preload force, regardless of the dimensional torque. This system also includes an electronic motor control unit, which enables the angle of rotation to be controlled during screw fastening. This drive concept is highly adaptable in terms of display, operation and implementation of special screw fastening processes, as well as evaluation of these processes.
