Definitions

  • the invention relates to a tool for processing stone or stone-like materials according to the preamble of claim 1.
  • the object of the invention is a tool for processing stone or stone-like materials that are dry but nevertheless allows fast and low-wear processing of the material
  • a related task is that the method has the ability should offer the grinding dust etc., e.g. by suction, completely from the To be able to remove the processing point.
  • An essential feature of the invention is that the tool with cutting PCD segments (polycrystalline diamond).
  • This with PCD cutting equipped tool is excellent for dry, but also wet, processing of stone or stone-like materials.
  • Another advantage is that the processing of the stone or stone-like Materials significantly faster compared to conventional tools can be done. Experiments have shown that the doubling of the Achieve processing speed, in individual cases even much more leaves.
  • Another advantage of the invention is that the presence of Foreign materials occurring in the stone material, e.g. Plastics, Lime deposits etc., does not affect the machining process. At conventional tools was a presence of foreign materials significant problem.
  • the PKD segments or cutting at a negative angle (rake angle) to the direction of rotation or direction of rotation of the tool are used.
  • This angle can Range from 0 ° to approx. 10 °.
  • the angle is preferably approximately 5 °.
  • the tool is generally a milling tool educated.
  • the milling head - in the direction of rotation - is in the area in front the PCD cutters arranged chip spaces that are negative in the direction of rotation, ie against the direction of rotation in a tangential direction to the radius at an angle run from 0 to 10 °. This so-called axis angle is therefore negative Direction of rotation arranged.
  • Another advantage of the invention is that the tool or the PCD segments can be resharpened several times, or at Damage etc. are easily exchangeable.
  • Milling tools with different diameters and different number of cutting edges can be provided. Also plays the shape of the Milling head essentially no role. For editing or for that It is also important that the tool is dynamically balanced Damage to the machine or the tool itself can be avoided (Bearing damage).
  • the tool is generally used as a sawing tool educated.
  • On the disc-like base body are one on the outer circumference Variety of PCD segments arranged. The number of cutting segments depends on the speed and the feed of the cutting tool.
  • the PCD segments are again at a negative angle to the Direction of rotation of the tool arranged, the so-called negative Rake angle can be between 0 and 10 °. An angle of 5 ° is preferred.
  • the one behind the cutting edge Arranged so-called deflectors must be coordinated depending on the material, i.e. the length of the deflector edge must be set depending on the material.
  • this deflector edge is not continuous, for example in Height of the upper cutting edge, but the deflector edge to interrupt a recess that is dimensioned depending on the material. This has the Advantage that the frictional resistance between the face of the saw blade and the Material is reduced.
  • the PCD segment is lateral, i.e. left and right on Diameter, chamfered. This has the advantage that the saw blade centers that the PCD segment is not damaged and that the cutting edge is protected.
  • the PCD cutting edges have a flank clearance angle that is between 0 and 2 ° is.
  • the radially inward outer PCD cutting edges several additional PCD cutting edges on the side flanks of the saw blade are arranged. These so-called clearing teeth provide for free-running saw blade in the material, so that a clamping of the saw blade in the Material is avoided.
  • FIGS 1 to 3 show an embodiment of the tool as Milling tool.
  • the milling tool is as so-called mushroom head milling cutter, which has a base body 1, which is provided on its surface with a plurality of plate seat grooves 3, which run outwards in a star shape from the center of the milling cutter.
  • the PCD segments 4 according to the invention individually or arranged in pairs and preferably by soldering in these grooves 3 attached.
  • chip spaces 2 Seen in the direction of rotation 9, so-called chip spaces 2 are located in front of the grooves 3 arranged, also over the length of the grooves 3 from the center of the The tool runs outwards in a star shape.
  • Cooling channel bores 7 can be arranged, through which cooling liquid if necessary emerges and reaches the area to be processed.
  • the PCD segments 4 consist of a hard metal body 5, which in the direction of rotation of the tool with PCD material 6 is coated.
  • the outer PCD segments are shown in FIG. 3, in front of which seen in the direction of rotation 9, in turn a chip space 10 is arranged is.
  • the PCD segments 4 are all at a negative rake angle 12 with respect to the Direction of rotation 9 arranged, the rake angle is preferably 5 °.
  • the milling head 1 has a receptacle 8, by means of which it is attached to a Drive motor is attached.
  • Figures 4 to 7 show a further embodiment of the tool as Sawing tool.
  • This has a base body 13 which in a known manner as flat saw blade is formed with a central receptacle 14.
  • the base body 13 carries a large number of PCD segments on its outer circumference 16, viewed in the direction of rotation 22, in front of these PCD segments 16 again chip spaces 15 are provided.
  • the saw blade has so-called cutting edges Voltage compensation holes 17 on ( Figures 6 and 7), which have a slot 18 are connected to the chip spaces 15.
  • Voltage compensation holes 17 on ( Figures 6 and 7) are seen in the direction of rotation 22 behind the PCD segments 16 at the level of Outside edge of these segments so-called deflector 20 is provided, which in limit the penetration depth of the cutting edges 16 into the material in a known manner.
  • the PCD segments 16 are again in relation to the Direction of rotation 22 arranged at a negative rake angle of preferably 5 °.
  • FIG. 4 and in particular the detail section according to FIG. 7 also shows that radially inward of the outer PCD segments 16 distributed over the circumference of the Base body 13 several other PCD segments 19 in the same orientation the side flanks of the base body 13 are arranged. These PKD segments 19 serve as so-called clearing teeth, which cover the cutting area of the Keep the saw tool free.
  • FIGS. 8 and 9 finally show a further embodiment of a Milling tool according to the invention.
  • a milling head 23 which is designed as a mushroom head milling cutter, PCD residues 24 butt-soldered.
  • the milling head 23 otherwise has a essentially smooth surface, and in particular has no chip spaces.
  • the milling head 23 is attached to a motor.
  • This milling head 23 has the particular advantage that in this way butt soldering of PCD residues 25 very quickly and very easily its cutting action can produce very good milling tools.
