  • PCD polycrystalline diamond
  • all materials are suitable for producing the segments 15, 15a, which ensure the properties of cutting tools and which can be permanently connected to the carrier tapes 11a, 11b.
  • inventively preferred starting components shown in Figures 1 and 2 for the production of saw blades or saw bands have the advantage of the invention that by a cutting process with low Effort two bimetallic bands or bimetallic leaves can be generated. It is likewise preferred according to the invention to connect a plurality of the starting components shown in FIGS. 1 and 2 to one another via further segments to be arranged. It follows that not only two, but a larger number of bimetallic bands can be produced by the simple cutting of the segments and carrier tapes.
  • FIG. 1 shows a preferred starting component which is constructed from the first carrier tape 11a and the second carrier tape 11b.
  • the carrier bands I Ia, I Ib each include a first and a second end face, wherein the first end face is preferably narrower than the second end face.

  • the preferred starting component is produced with fewer working steps than a comparable number of bimetallic bands.
  • the starting component is characterized by better storage possibilities and can be transported with less effort.
  • the output component is divided into two bimetal bands by approximately straight-line separation or cutting of the continuous segment 15.
  • the cutting within the continuous segment 15 preferably takes place in such a way that a part of the segment 15 remains on both carrier bands 11a , 11b.
  • a cutting contour is then preferably milled into the bimetallic strips produced.
  • the tooth tips are formed by the remainders of the segment 15.
  • hardening of the saw blade pre-body preferably takes place, which, if necessary, is subsequently finished by grinding or worked to exact dimensions.
  • the starting component shown in Figure 1 is cut along the cutting line 18, as shown schematically in Figure 3.
  • the cutting line 18 preferably runs within the continuous segment 15. It is also preferred that the cutting line 18 runs partially in the carrier bands 11a, 11b, provided this supports the further production of the saw blade. Based on the course of the cutting line 18, two bimetallic sheets or bimetal belts with offset segments 15 result. Because of their shape, the cutting line 18 roughly indicates the later cutting contour of the saw blade to be produced. This relationship between the shape of the cutting line 18 and the later cutting contour of the saw blade to be produced is schematically shown in FIG Figures 4 and 5 shown. FIG. 5 shows an enlarged illustration of the area circled in FIG.
  • contoured cutting Since the later contour of the saw blade is approximated by the course of the cutting line 18, this process is also referred to as contoured cutting. Due to the accuracy of the near-contour cutting, further processing steps, such as, for example, milling or grinding, can be reduced to a minimum or even saved.
  • a hardening of the connection between the carrier strip and the segment takes place. Since the cutting or near-contour cutting is carried out under the influence of heat, for example with the aid of lasers, mechanical stresses, microstructural changes and / or glass phases and the like remain in the cut materials. These mostly negative effects relax during hardening. In addition to largely eliminating the negative effects mentioned above, the hardening forms the basis for the subsequent grinding of the bimetal bands produced. Without the hardening process, the grinding would be hampered by the too soft materials, for example because the grinding tools smeared. In addition, the contour-near cutting in combination with the hardening supports the subsequent grinding, because due to the accuracy of contour-near cutting only small amounts of material must be removed. On this basis, a milling of the starting component is preferably saved.
  • a first carrier band 11a and a second carrier band 1b are connected to one another via a plurality of segments 15a.
  • the segments 15a are made of a suitable cutting material.
  • the segments 15a are arranged regularly, periodically and / or irregularly along the longitudinal direction of the carrier tapes 11a, 11b in order, for example, to reduce vibrations in a later sawing process or even to completely prevent them.
  • the spacing of the plurality of segments 15a is also adapted to the tooth contour 17 to be generated later on (compare FIGS. 4, 5, 6 and 7).
  • the relationship between the spacing of the segments 15a and the later cutting contour 17 is preferably based on the fact that the segments 15a after machining form the tip regions of the teeth of the produced saw blade.
  • the output component according to FIG. 2 is separated in such a way that portions of the segments remain at the opposite end sides of the carrier tapes 11a, 11b.
  • the starting component shown in Figure 2 is hardened consisting of the Illustrated bands I Ia, 1 Ib and the connecting segments 15a. Since the segments 15a are connected via relatively short sections to the carrier tapes IIa, 11b, the heat treatment during hardening produces only a relatively small distortion of the starting component according to the invention. This distortion is based on the different elongation behavior of the materials used for the carrier tapes I Ia, I Ib and the segments 15a become. Due to the lower distortion, the adaptation of the materials of the carrier tape and the segment to one another is facilitated in order to compensate for the remaining distortion. Furthermore, the reduced or almost completely raised distortion forms a better starting point for the further processing of the starting component.
  • the hardening process forms the basis for a subsequent grinding, since the grinding of hardened material takes place in comparison to non-hardened material with reduced tool loading. This is due to the fact that the hardened material, for example, does not lead to a "smearing" on the grinding tools.
  • an output component is provided which is comparable to a close-fitting cut double bimetallic strip. It follows that preferably only a small material removal is required to achieve the final shape of the saw blade. This preferably saves the step of milling and, in addition, in conjunction with the hardening process, supports immediate accurate production of the saw contour with the aid of grinding. It follows that, due to the above-described production of Trust ⁇ component work steps and thus costs in the production of shegeblät- terr ⁇ or saw bands are saved.
  • the segments 15a are separated so that portions of the respectively cut segment 15a opposite the opposite end faces of the carrier bands IIa, Ib remain.
  • the hardened bimetallic strips or bimetal strips produced in this way are brought into the shape of the final cutting contour by grinding, punching or other preferred shaping processes.
  • the near-contour cutting may preferably also extend beyond the segments 15a into the carrier bands 11a, 11b.
  • This contours near cutting leads to the tooth contours 17, as shown by way of example in Figures 6 and 7.
  • This preferred design of the manufacturing process leads to an optimal material utilization, so that the loss of expensive cutting material is reduced and costs are saved in this way.
  • the near-contour cutting leads to a tooth contour, which only requires a small post-processing in order to achieve the final geometries of the saw blade to be produced. Since the starting component processed here is already hardened, this post-processing is carried out by means of grinding operations, which are also associated with low tool loads and thus also at low cost.
  • the cutting contours of two later tooth tips are preferably arranged in a segment 15a.
  • the rounded tooth contour areas are positioned close to one another, while the rectilinear areas - preferably approximately perpendicular here - are arranged near the outer edge of the segment 15a.
  • the size of the segment 15a is adapted to the desired tooth contour such that as little material as possible has to be removed as excess.
  • the tooth contours are preferably arranged in the segment such that the above-mentioned rectilinear regions are located opposite one another. This leads to material savings, especially with a relatively narrow, pointed upwardly projecting tooth contour.
  • the amount of excess material or the allowance that needs to be scheduled in the near contour cutting of the segments is related to the heat load during cutting. This follows from the heat-stressed or heat-damaged zones that may arise during cutting. Therefore, it is also preferred according to the invention to select the heat load during cutting or in general during machining such that the heat-stressed zones are kept small and thus reduce the oversize.
  • the shape of the segments is also varied when viewed from the side, as shown in FIGS. 1 and 2.
  • This form of variation preferably has the goal of creating an example, not only rectilinear interface between the segment and carrier tape. This interface between carrier tape and segment is loaded during a subsequent sawing process by strong mechanical stresses. Due to the preferred course of this interface, a mutual Ab ⁇ support between segment and connected carrier tape.
