Abstract
A milling device comprises two milling bodies one of which is hollow and encloses the other, and a driving unit connected to one of the milling bodies via a shaft nonrotatably connected with the one milling body to cause it to rotate about its own axis in rolling contact with the other milling body. Both milling bodies are universally movable in a surface essentially transverse to the axis of rotation, but are actuated by a return force which increases as the pendulum movement increases. To provide for the return force, the two milling bodies are supported in pendulum fashion, or use is made of resilient means, such as springs.
