Abstract (en)
The present disclosure generally relates to a milling device (10). The milling device (10) includes a first row of cutting discs (14) mounted on a first circumference, and a second row of cutting discs (18) mounted on a second circumference. The second row of cutting discs (18) is offset from the first row of cutting discs (14) in a longitudinal direction of the milling device (10), and the second circumference is arranged relative to the first circumference such that the second row of cutting discs (18) projects at least in part radially outward from the first row of cutting discs (14). Therefore, the first and second rows of cutting discs (14, 18) cut a material to be removed at a different depth, with a predetermined distance (X) formed between the cuts in order to achieve a substantially continuous milling line.
