Title: METHOD AND DEVICE FOR MILLING STONE MATERIAL OR STONE-LIKE MATERIAL
Abstract:
The invention relates to a method for milling a road surface (3) made of asphalt (B) or concrete. A rotating milling tool (4), which is equipped with a plurality of milling elements (5) around its circumference, is brought into milling engagement with the road surface (3) and is moved along same such that material (B) is milled from the road surface (35) along the path of movement. According to the invention, the rotational movement (R) of the milling tool (4) and the advance movement (V) are superimposed by a force-controlled or path-controlled vibrating movement (S, DS, DM) of the milling tool (4) such that during the milling of the material (B), there is a periodic loss of contact between the milling elements (5) of the milling tool (4) currently in a milling engagement, and the material (B) to be removed. Using the method according to the invention, outstanding rates of removal can be achieved with little wear to the tool and using relatively simple and robust milling devices.
