Definitions

  • the invention relates to a mounting holder for a cutter head with a clamping wedge 1 and a counter wedge.
  • Such mounting brackets are used in rotating tools for machining wood, plastics and similar materials and are used in recesses or grooves in the cutter heads and are preferably fastened therein by means of clamping screws.
  • the known mounting brackets either have the indexable insert supported by the counter wedge or additionally a cutter holder in order to insert a hard metal cutting strip between this and the counter wedge (see for example DE-GM 76 02 409).
  • the known mounting brackets including the cutting edge, consist of at least three parts.
  • indexable inserts are used, they must have a certain thickness so that they can be securely held in the groove by the counter wedge or the clamping wedge. However, this means that cutting of, for example, a thickness of less than 1.5 mm can no longer be securely held in the groove of the cutter head by means of an installation holder formed from clamping wedge 1 and counter wedge.
  • the solution according to the invention is intended to open up the possibility of using almost any thin cutting edges.
  • the object is achieved according to the invention in that the counter wedge protrudes beyond the diameter of the cutter head and the cutting edge is an integral part of the counter wedge.
  • This solution makes it possible for the first time to provide a mounting bracket that consists exclusively of a clamping wedge and a counter wedge. As a result, installation in the groove of a cutter head can be carried out without difficulty. Since the cutting edge is an integral part of the counter wedge, it is ensured that the cutting edges are of any thickness, preferably of 0.5 mm, but also up to max. can preferably have of 1.5 mm. This is particularly advantageous if the cutting edge consists of polycrystalline synthetic diamond. In an embodiment of the invention, the polycrystalline synthetic diamond is preferably fastened to a hard metal base, which in turn is insolvably embedded in the counter wedge, for example by soldering.
  • a mounting holder 10 is shown, the one insert 12 in a groove 14 Cutter head 16 holds.
  • the mounting holder 10 consists of a clamping wedge 18 and a counter wedge 20.
  • the indexable insert 12 is arranged between a flange of the groove 14 and an outer surface of the counter wedge 20.
  • a clamping of the clamping wedge 18 and thus of the counter wedge 20 and the indexable insert 12 is then preferably carried out by means of a clamping screw 22 , which in turn determines the processing time for workpieces.
  • a mounting bracket 26 is shown, which is designed according to the invention.
  • This mounting bracket also consists of a clamping wedge 28 and a counter wedge 30, both of which are inserted into a groove 32 of a known esser head 34.
  • a cutting edge 36 which preferably consists of polycrystalline synthetic diamond, is embedded in the chest surface of the counter wedge 30 as an integral part. Since these diamond cutting edges have a thickness of max. 1.5 mm, they are attached to a non-metallic base, which is not shown, before they are inserted into the counter wedge. As can be seen particularly from FIG.
  • the length of the area of the counter wedge 30 projecting beyond the diameter of the cutter head 34 can determine the cutting flight circle, which is considerable can be chosen larger compared to the cutter heads that use an indexable insert according to FIG. 1.
  • the flight circle which is achieved by the inventive construction of the mounting bracket 26 is provided with the reference symbol 38 in FIG. 2.
  • the flight circle of a knife head with recessed indexable inserts has the flight circle 40.
