MBR magnetic blocks serve as additional support to reduce vibration when the workpiece overhangs the magnetic clamping plate or if 2 magnetic clamping plates are mounted at a large distance. Likewise MBR magnetic clamping blocks can form the 3-point support of the workpiece outside the magnetic chuck. On one side, the MBR is equipped with a powerful permanent magnetic base. The other side is brought to desired height above the massive, self-locking trapezoidal spindle. The MBR allows to set all levels needed for our magnetic clamping systems - from 82mm to 114mm. With additional adapter discs that are simply screwed onto the system, the height (H) can be Extended.
