A floor milling machine with a sensor device for contactless determination of wear of the chisel apparatuses and methods for contactless determination of wear on the bit means of a surface milling machine of a

摘要

The invention relates to a surface milling machine of a (1), in particular a road, a recycler, a stabilizer or a surface miners, with a milling drum (7) with a along its axis of rotation (18) extending cutting rollers width (a) and at least two chisel devices (6), each of which has a chisel (9) and a chisel holder (10), and a sensor device (14) for the contactless determination of wear on the at least two chisel devices (6), comprising a sensor (8, 8 '') for measuring a wear parameter of the at least two chisel devices (6), wherein the sensor (8, 8'') at least over a part of the cutting rollers width (a) is movable, in order to measure the wear parameter of the at least two chisel devices (6) a same measuring angle (α) and a same relative position of the sensor (8, 8 '') with respect to the at least two chisel devices (6) to adjust. The present invention also relates to a process for the contactless determination of wear on the at least two chisel devices (6) of the surface milling machine of a (1).
