Safety through direct clamping: ROBA®-guidestop safety brakes clamp directly onto the linear guide with very high rigidity. They are therefore attached directly to the moving masses. Drive elements between the motor and the moving mass, such as spindle, spindle nut, shaft coupling or gearbox, therefore have no influence on safety.
Perfect for vertical axes: Due to the direct clamping on the linear guide, the ROBA®-guidestop is ideal for use in gravity-loaded axes in order to minimize the risk of danger to persons.
Relief for spindle and guide: The ROBA®-guidestop takes over the load when the axis is stationary, for example during machining. In this phase, the drive motor can be switched off and taken out of control. This eliminates the control movements and thus protects the ball screw. The closed brake absorbs axial forces. The service life and maintenance intervals of the drive components are extended.
More precise with higher cutting performance: The backlash-free clamping additionally stiffens the NC axis. This increases the process accuracy, increases the cutting performance and brings advantages in heavy machining. Machining is less subject to vibrations and the surface quality of the workpiece can be improved as a result.
