The Rösler RMBS engine block blasting machine is a turbine blasting machine characterised by a special gripping arm, known as the manipulator clamp. The manipulator clamp and its associated gripping jaws are used to grasp engine components weighing up to several tonnes and place them into the machine.

Once inside, the workpieces are rotated and oscillated during the blasting process so that, during desanding for example, the core sand can be removed without leaving any residue, even from complex internal geometries, and so that no blasting media accumulates there. Instead of a single large part, several small parts can also be processed in the RMBS.
