BERG Capto Hydraulic Self-Locking Clamping Systems

The self-limiting clamping system for Coromant Capto tools developed by BERG Spanntechnik is used in conjunction with Coromant Capto clamping sets. In this solution the wedge drive is rigidly connected to the clamping set via a drawbar. The wedge drive can be directly hydraulically or mechanically actuated. The absolute self-limitation of the system guarantees high mechanical overall rigidity of the interface in conjunction with maximum clamping reliability. The direct hydraulic actuation, in particular, permits extremely small installation spaces with low operating pressures for the complete clamping and chucking system.

Design Features

A double-acting cylinder leads directly into a clamping cone which has a very low gradient. During clamping this clamping cone presses the pressure elements resting on it into the similarly tapered housing hole. This displaces the wedge piece in the axial direction. As the wedge pieces rest in windows of the main drawbar, they are also axially displaced (clamping stroke). The cone angle and surface properties are designed to guarantee absolutely reliable self-limitation. In addition to the hydraulic actuation the system can also be driven dry by direct connection to draw/push-bar. All systems are completely maintenance-free due to their respective surface properties!

Accessories

Adapters, hydraulic units, clamping force measuring device, volume flow measuring device for stroke control.
