BERG Spanntechnik offers manually, mechanically and hydraulically actuated Coromant Capto TM clamping systems for static and rotating applications tailored to the requirements of the application. This especially applies to applications with a very limited installation space.

Questo cilindro elettromeccanico di sblocco è utilizzato per comprimere il pacco di molle e azionare il tirante per il blocco e lo sblocco dell' utensile nei mandrini dei centri di lavoro. Il controllo interamente integrato comunica con la macchina con protocollo via field-bus standard.

Value engineering has led to frequent demands for the design of an "all electric" machine. New electromechanical clamping systems have been developed for some applications, allowing machine manufacturers to completely do without hydraulics / pneumatics in the field of clamping technology. The modern electromechanical clamping cylinder EV is suitable for actuating power operated cylinders on high-end, dynamic lathes independent of the machine control system.

Power operated chucks according to the BERG wedge bar principle have been available from BERG Spanntechnik for more than 30 years. Optimisation of this functional principle permits extremely high clamping forces with maximum open centre capacity and minimum influence of the rotational speed on the clamping force. These advantages have now been transferred to the small construction sizes with a chuck outer diameter < 100mm for applications in highly productive machines.

Combined rotary joints for supplying hydraulic oil, coolant lubricant and compressed air are used in many machine tool applications. These rotary joints are available according to customer specifications for rotational speeds of up to 10,000 rpm, and up to NW8.

The Hydrodock clamping system is used as a clamping system for machine tool interfacing with exchangeable equipment. The effective self-locking feature of the system guarantees high mechanical rigidity of the interface combined with maximum safety. Therefore no permanent pressure is required after the clamping process. Such clamping systems permit an admissible retaining force of up to 500kN after clamping.
