  • cutting rollers or cutting heads are rotatably mounted transversely to the longitudinal axis of the cantilever arm on a cantilever arm, which are guided transversely to its axis of rotation in the vertical direction over the working face and are used in this way for the degradation or recovery of materials.
  • Such cross-cutting heads are characterized as well as cutting rollers essentially by the fact that the bit wear can be optimized by appropriate positioning and adjustment of the angle relative to the direction of rotation, which when working with such Wegschrämmaschinen first Einbrechschrämvorgang is required, in which the cutting heads in the direction of the axis of the Ausler- arm must be inserted into the working face to redesignschrämen a burglary, starting from which then the face can be swept over.
  • longitudinal cutting heads which have an axis of rotation which is substantially parallel to the axis of the cantilever arm or aligned with the axis of the cantilever arm.
  • Einbruchschrämen is required before the actual mining operation, in which case the longitudinal cutting heads must work in the direction of its axis of rotation in the working face to ensure a corresponding burglary, starting from then the pivoting of the boom with the rotating L jossschneidköpf on the working face takes place and the degradation can be made.
  • a disadvantage of the types described is that they are not suitable for use at low line height due to their relatively large height. Without special adaptations, the types described can not be used for the mining of very hard rock.

  • the cutting wheel is rotatably mounted on a cantilever arm, which is pivotable both in the vertical direction and in the horizontal direction.
  • the axis of rotation of the cutting wheel extends in the horizontal direction and in a second embodiment in a substantially vertical direction.

  • the tool carriers are now disc-shaped, the requirement of the low overall height of the section boring machine can be taken into account in a simple manner. Because now at least two parallel to each other ange- arranged disc-shaped tool carrier are provided, the cutting performance is improved and at the same time ensures a common storage of the two tool carrier on a arranged between the tool carriers, at least partially disc-shaped end portion of the cantilever arm in a simple manner.
  • the tool carriers are in this case mounted rotatably in particular exclusively on the said end region of the extension arm arranged between the tool carriers, and this is therefore a so-called flying bearing. From a flying storage is when the tool carrier is mounted only on one side, so an opposite second bearing is not available. This leads to a particularly flat construction.
  • a storage of the tool carrier is avoided on the respective outer sides, so that, for example, a tool carrier encompassing frame or the like, which would be required for such storage, can be omitted. This not only saves space, but in particular the fact that the cutting tools can be effective with suitable positioning up to the edge of the cutting device.
  • the track boring machine according to the invention can be used for different widths and different high section profiles, without the need for a structural adaptation of the machine.
  • the cantilever arm is preferably mounted on a carriage which is displaceably guided relative to the base frame in the machine longitudinal direction, whereby a collapse into the working face is made in a simple manner and then by means of pivoting of the boom can be removed corresponding to the depth of the burglary corresponding rock layer.

  • This arrangement of the tool carrier leads to a very low machine height, so that the machine can also be used for low route profiles.
  • the cutting tools are arranged on the two tool carriers in such a way that they intersect two grooves separated by a rock rib into the working face, the burglary depth being dependent on which diameter the bearing of the two tool carriers is offset compared to the cutting circle diameter.

  • the rollers or disc packets have a plurality of rows of cutting inserts on their circumference
  • the cutting principle is not used, but the cutting inserts formed in particular by cemented carbide inserts break the rock due to the cutting forces introduced substantially perpendicularly to the working face.

  • a bearing is required which has a corresponding space requirement, in particular in the axial direction of the tool carrier, so that the cutting inserts of the disc packs or rollers can not reach the edge of the tool carrier to effect and this in particular in particular when rotational axes of the disc packs or rollers run parallel to the axis of rotation of the tool carriers.
