Definitions

  • the present invention relates to a cutting tool for cutting natural stone, concrete, ceramic and the like according to the preamble of claim 1.
  • Such cutting tools usually have metallic master blades, the diameter of which is up to 4 m.
  • Cutting segments are attached to the circumference of the base sheet, which have industrial diamonds in a holding compound. The width of these diamond segments determines the cutting width.
  • the cutting segments have at least one channel extending over their height, which promotes the discharge of the machined material.
  • the course of the channel or channels can be substantially wavy, zigzag or meandering in the circumferential direction, but it is also provided that the or each channel is designed as a deep groove which runs obliquely or curved.
  • Several grooves can be arranged in parallel or at the same distance; Groups of such grooves can intersect, especially at an acute angle. According to the invention, good transport routes are thus created for the outflow of the chipped material, while at the same time achieving a higher cutting performance.
  • the special design of the cutting segments also means that less friction occurs on the side surfaces of the cutting segments, so that less frictional heat is generated and the cut produced has smoother contours than can be achieved with conventional, high-friction cutting segments.
  • the channels provided according to the invention additionally improve the cooling of the cutting segments, which results in longer tool lives.
  • the designs of the cutting segments and their channels specified in the subclaims serve to further increase the cutting performance with improved material removal, which takes place both in the unfair direction and at right angles to it. Especially with serrated or serrated cutting segments, there is only edge friction on the outside, but a full-surface cut is still guaranteed. It is important that the individual cutting pieces of each cutting segment engage each other in such a way that there is no gap in the axial direction, but that there is full cross-sectional coverage.
  • the channels form an arrow structure with respect to the circumferential direction, the removed material is continuously drained off well in the direction of flow, to a large extent in the circumferential direction and partly also obliquely thereto, i. H. towards the side faces of the cutting gap.
  • the cutting tool drawn in sections in FIGS. 1 to 3 has a master blade 10, on the circumference of which there are 12 notches 14 which separate individual cutting segments 16 from one another.
  • Each cutting segment has grooves or ridges 18 which alternate with apex parts 20. Longitudinal channels 22 are thereby formed in the circumferential direction U. The surfaces of the cutting pieces are essentially parallel to one another at such a distance that there are no gaps in the axial direction A, but there is full cross-sectional coverage. As can be seen from FIGS. 1 and 2, both the cutting pieces and the channels 22 of the cutting segments each extend over their entire height h.
  • the cutting segment surfaces can also be formed asymmetrically, e.g. B. sawtooth-shaped.
  • Another embodiment is shown in FIG. 4.
  • the longitudinal channels 22 are wave-shaped, so that there are softer transitions, which can promote the material discharge.
  • the design is also chosen here so that the mutually opposing apex parts 20 ensure full cross-sectional coverage in the axial direction A.
  • FIG. 5 Yet another embodiment is shown in FIG. 5.
  • the cutting segment 16 shown here has, in addition to a central channel 24, which lies in the central plane 30 of the master blade 10 (omitted here), also oblique side channels 26 and V channels 28. It can be seen that such cutting segments 16 have an arrow structure, due to the machined material is carried out particularly well both in the circumferential direction and at an angle to it. Since the individual cutting pieces have the same shape over the entire height (h), a uniform cut is also ensured if the effective height becomes less and less with increasing wear.
  • Important advantages of the invention are based on the fact that, on the one hand, less frictional heat is generated as a result of reduced edge friction and, on the other hand, this is continuously dissipated well in each cutting segment thanks to the channel systems. This contributes significantly to increased tool life, increased cutting performance and smoother cutting surface.
