    Abstract: The invention relates to a milling machine, in particular a road milling machine, a stabiliser, a recycler or a surface miner, comprising a drive means which is configured such that the milling machine performs translatory and/or rotatory movements on the ground, and a working means which is configured such that the ground is machined. The invention also relates to a method for operating a milling machine of this type. The milling machine according to the invention has a control unit 15 to input drive parameters and work parameters. The control unit 15 is distinguished by a selection unit 15C to select an operating mode from a plurality of operating modes. The control and processing unit 20 has a memory 20A which stores at least one predetermined drive parameter which is assigned to the operating mode, and/or at least one predetermined work parameter which is assigned to the operating mode, for each operating mode of the plurality of operating modes. The control and processing unit 20 is configured such that at least one assembly 4, 5; 8, 10, 11, 12, 13, 17, 18, 19 of the drive means and working means is controlled subject to the at least one drive parameter or work parameter which is stored in the memory 20A for the operating mode selected using the selection unit 15C, such that the particular machine function is carried out. The milling machine further provides that at least one function which describes the dependence of a work parameter of one assembly on a drive parameter of another assembly is stored for each operating mode, the control and processing unit 20 being configured such that, based on this function, at least one assembly of the working means or drive means is controlled such that the particular machine function is carried out.

    Abstract: The invention relates to a tool combination consisting of a chisel holder, which can be fastened to a milling drum of a soil tillage machine, and at least one leading and one trailing chisel, which are retained on the chisel holder, wherein the trailing chisel is arranged after the leading chisel, based on a working movement of the tool combination in use in the soil tillage machine, and wherein each chisel has a chisel tip having a cutter. According to the invention the trailing chisel tip of the trailing chisel has, at least in some areas, a greater hardness than the leading chisel tip of the leading chisel. Thus stoppage times of the soil tillage machine for maintenance can be reduced and the loss of chisels can at least be decreased.

    Abstract: The invention relates to a chisel (10) having a chisel head (11) and a chisel shaft (17), wherein near its end facing away from the chisel head the chisel shaft has a threaded portion having a thread (19), wherein the chisel head holds a chisel tip (20) made of a hard material, and wherein near the side facing the chisel shaft the chisel head is provided with a supporting surface (15). Especially when superhard hard materials are used for the chisel tip, a load-optimized chisel design is obtained by a domed supporting surface (15).
