Definitions

  • the invention relates to a conditioning device for Grinding disks for processing the edge areas more plate-shaped Items such as B. glass panes or the like, with the grinding wheels in conditioned Condition at least one revolving, towards the center of the grinding wheel rejuvenating at least in one area Have groove.
  • rod-shaped Conditioning devices In practice, such are usually rod-shaped Conditioning devices known, mostly from a mineral or mineral components Made of material whose abrasive effect binds the resetting the grinding wheel to be conditioned.
  • Components of the material include a. alumina (Corundum) and silicon carbide. The cross section is included cuboid and the material properties are in the entire conditioning device uniform.
  • the conditioned grinding wheel has a rotating one Groove that tapers towards the center of the grinding wheel and in particular an approximately semicircular one Cross section.
  • Conditioning is essentially influencing including the sharpness of the grinding wheel surface understood the groove surface, the groove contour should be preserved as long as possible. Furthermore, under Conditioning also the introduction or rework one worn and worn out by many grinding processes or almost completely disappeared groove shape Roger that.
  • the contour of the conditioning device quickly changes Adapts the contour of the groove, and therefore no influence given the groove by the conditioning device conditioning, especially profiling, in practice usually by EDM with an electrode profiled according to the groove shape.
  • the object of the invention is to overcome the aforementioned disadvantages to avoid and a conditioning device for grinding wheels for processing the edge areas more plate-shaped Items such as B. glass panes or the like, the grinding wheels in the conditioned state at least one revolving, each to the center of the grinding wheel have a tapering groove at least in one area, specify with which a conditioning of these grinding wheels easily and without expensive equipment everywhere and is possible at any time.
  • This will be a homogeneous Sharpness is achieved over the groove contour, and it can be both a profiling as well as a profile-maintaining sharpness influence in one operation without removing the Grinding wheel done.
  • the width of the Conditioning device essentially the width of the Correspond to groove (s) and the volume curve across the width the conditioning device according to the depth profile from one side edge to the other side edge of the groove (s) with increasing volume with increasing depth to be achieved be designed so that by varying the number and Size of embedded pores or in particular as lateral grooves or the like trained free spaces a more or less strong conditioning takes place.
  • the width of the conditioning device can be essentially correspond to the width of the groove (s) and the abrasive Properties of the material of the conditioning device accordingly across the width of the conditioning device the depth course from one side edge to the other Side edge of the groove (s) with better abrasive properties trained with increasing depth to be achieved his.
  • the width of the conditioning device can also be according to the invention essentially the width of the groove (s) correspond and the coordination of the grain size distribution in Regarding the chip spaces of the grinding wheel across the width the conditioning device according to the depth profile from one side edge to the other side edge of the groove (s) with better coordination with increasing to be achieved Be formed depth so that a greater removal or a better focus on the deeper ones Groove areas takes place.
  • the conditioning device can in particular be rod-shaped and during use corresponding wear a translatory feed experienced in the direction of their longitudinal axis, but so are other shapes, such as B. a semicircular disc-shaped Design or the like possible, the cross section as described above and along the feed direction is constant.
  • the cross section of the conditioning device or that which is in engagement during the conditioning Range of the conditioning device approximately be triangular, so that with a simple Geometric shape to be produced a desired groove shape is achievable.
  • the cross section of the conditioning device or the one in engagement during conditioning Area of the conditioning device approximately diamond-shaped be designed so that with the same length profile less sharp cross-section results, that with axisymmetric Training without attention to a processing device can be used for conditioning.
  • the conditioning device a plurality of surrounded by a holding device Assemble parts so that by arrangement the partial components inside or outside the area of intervention during the conditioning device Contour of the conditioning device set and thus the contour of the groove to be achieved can be selected. This can be done with a single conditioning device a variety of different groove shapes and widths processed and conditioned.
  • the partial components can be made of materials with different materials Material properties exist so that a further influence of the conditioning device groove to be achieved in the grinding wheel by means of the variation of the material of the partial components is.
  • the conditioning device can advantageously be made of a mineral material with one for conditioning suitable grinding wheel and a have a suitable abrasive effect.
  • the invention further relates to a method for conditioning of grinding wheels for processing the edge areas plate-shaped objects, such as. B. glass panes or the like, the grinding wheels in conditioned condition at least one revolving, itself to the center of the grinding wheel at least in one area have a tapered groove.
  • the tracking can be done manually or the tracking mechanically, especially automatically by spring force or controlled by a motor drive.
  • the grinding wheel 2 has one circumferential groove tapering towards the center of the grinding wheel 3, which is preferably an approximately semicircular Cross section.
  • the grinding wheel 2 can either completely from a suitable for material processing Grinding material or the grinding wheel 2 can be made of another material, such as. B. metal or the like be made and in a circumferential recess an embedded circumferential ring made of especially include mineral abrasive material.
  • the grinding wheel 2 e.g. B. at Grinding edge areas of plate-shaped objects, such as B. glass or the like
  • the profiled groove 3 worn and approaches the contour of the objects to be processed. This causes a proper processing of the edge areas to be sanded depending on the degree of wear of the groove 3 no longer possible is.
  • the blunting also leads to an increase of machining forces, what workpiece damage and Can cause profile errors.
  • Conditioning device 1 can have grooves 3 of any shape can be achieved without undercut.
  • Fig. 2 shows the cross section of another invention rod-shaped conditioning device 1, in which both one symmetrical in the longitudinal as well as in the transverse direction Training with straight flanks is provided.
  • Fig. 3 shows a further embodiment in which the Cross section symmetrical only with respect to the longitudinal axis is formed, as in the cross section 4.
  • the conditioning device 1 can both with forward pointed end, but can also be used vice versa.
  • FIG. 5 shows a further exemplary embodiment of the invention, where the conditioning device 1 from a Variety of sub-components 4 composed by a holding device 5 are at least partially surrounded.
  • Fig. 6 shows the object of FIG. 5 in a perspective View.
  • To influence the achievable Groove geometry can be all or only certain partial components 4 from the holding device 5 protrude and thus engaged during conditioning his. Both the total cross section of the conditioning device formed from the partial components 4 1 as well as the partial components 4 different Have shapes.
  • FIG. 7 shows a further exemplary embodiment of an inventive one Conditioner 1 shown that engages with a grinding wheel to be conditioned 2 is located.
  • the conditioning device 1 a semicircular disc-shaped shape, through 180 ° rotation of an approximately trapezoidal cross section its wider edge arises on. When there is wear the conditioning device 1 tracked in the direction of the arrow.
