Definitions

  • the invention relates to conditioning devices for grinding wheels for processing the edge regions of plate-shaped objects, such.
  • the grinding wheels in the conditioned state at least each have a circumferential groove, at least in a partial region tapering to the grinding wheel center.
  • rod-shaped conditioning devices which usually consist of a mineral or mineral constituent material whose abrasive action resets the bond of the grinding wheel to be conditioned.
  • Usual components of the material are u. a. Aluminum oxide (corundum) and silicon carbide. The cross section is cuboid and the material properties are uniform throughout the conditioning.
  • the conditioned grinding wheel has a circumferential groove which tapers towards the center of the grinding wheel and in particular has an approximately semicircular cross section.
  • Conditioning is essentially understood as influencing the sharpness of the grinding wheel surface, including the groove surface, with the groove contour being kept as long as possible. Furthermore, the term “conditioning” also refers to the introduction or reworking of a groove shape worn down and worn or almost completely disappeared by many grinding operations.
  • edge areas can both lead to a blunting of the affected grinding wheel surface, but it can also be a "Überschenfung" caused, which is also not desired. Both deviations from the normal sharpened desired state can be remedied by the conditioning.
  • the conditioning by means of the aforementioned rod-shaped conditioning devices takes place in that the conditioning device is provided with a matched to the groove cross-section profile to be achieved and is brought into engagement with the rotating grinding wheel, wherein the distribution of the sharpening effect over the entire Nutform is uniform and thus either subsections are not sufficiently sharpened or other parts too sharply.
  • the conditioning in particular profiling, in practice usually by sink eroding with an appropriately profiled electrode groove.
  • the disadvantage here is that a complex and expensive erosion device is required for this work-up, so that the worn grinding wheels usually have to be returned to the manufacturer or another specialist for refurbishment. This is both time-consuming and cost-intensive, since at least one replacement grinding wheel has to be provided for the bridging of the time until the return of the externally processed grinding wheel. This can cause a rather expensive storage in several grinding machines and / or a number of different profiled grinding wheels.
  • the object of the invention is to avoid the aforementioned disadvantages and a way to condition grinding wheels for processing the edge portions of plate-shaped objects such.
  • the grinding wheels in the conditioned state at least each have a circumferential, at least in a partial region tapered groove center, indicate that allows conditioning of these grinding wheels easily and without expensive equipment anywhere and at any time.
  • This is a homogeneous Sharpness achieved over the groove contour, and it can be both a profiling and a profile-preserving sharpness influence in a single operation without removing the grinding wheel.
  • a rod-shaped conditioning device for the conditioning of grinding wheels for processing the edge regions of plate-shaped objects, such.
  • the grinding wheels in the conditioned state at least one circumferential groove, at least in a partial region tapered groove center
  • the conditioning is used so that the conditioning device has a tuned to the desired groove cross-section, wherein the Abtrag is dependent on the length in the loop-engaging length
  • the width of the conditioning device substantially equal to the width of the groove (s) and the length profile from one side end to the other side end of the conditioner according to the depth profile from one side edge to the other side edge of the groove (s ) is formed with increasing length with increasing depth to be achieved.
  • the above-described disadvantages are further avoided by the method for conditioning grinding wheels according to claims 2 to 13.
  • the tracking can be done manually or mechanically, in particular automatically by spring force or controlled by motor drive.
  • the rotating grinding wheel can be conditioned accordingly by contact with the rod-shaped conditioning device, wherein the grinding wheel can remain clamped even in the grinding device.
  • the width of the conditioning device may be less than the groove, in which case only portions of the groove are conditioned.
  • the width of the conditioning device can also be greater than the width of the groove, wherein the protruding areas are removed unused.
  • the sharpening with as long as possible profile preservation and possibly also the profiling of the disc is done automatically by the specially trained cross section of the conditioning, since the removal is dependent on the length located in the loop engagement and the length of the conditioning corresponds to the depth profile of the groove.
  • the conditioning device which are tapered and thus have a length of approximately zero, virtually no removal is effected, whereas the central regions of the conditioning device have a greater length and thus achieve greater removal, which corresponds to the corresponding groove depth causes this point.
  • the width of the conditioning device substantially the width of the Groove (s) and the volume profile over the width of the conditioner according to the depth profile from one side edge to the other side edge of the groove (s) with increasing volume to be achieved with increasing depth to be achieved, so that by varying the number and size of embedded pores or especially as lateral grooves or the like formed free spaces a more or less strong conditioning takes place.
  • the width of the conditioning device may correspond substantially to the width of the groove (s) and the abrasive properties of the conditioner material over the width of the conditioning device according to the depth profile from one side edge to the other side edge of the groove (s) with better abrasive properties as the condition increases be formed reaching depth.
  • the width of the conditioning device can essentially correspond to the width of the groove (s) and the coordination of the particle size distribution with respect to the chip spaces of the grinding wheel over the width of the conditioning device according to the depth profile from one side edge to the other side edge of the groove (s) better coordination can be formed with increasing depth to be achieved, so that a stronger removal or a better sharpness influence of the deeper groove areas takes place.
  • the conditioning device may be designed in particular rod-shaped and experienced during use with appropriate wear a translational feed in the direction of its longitudinal axis, but there are also other forms such.
  • the cross-section of the conditioning device or the area of the conditioning device which is in engagement during the conditioning can be approximately triangular, so that a desired groove shape can be achieved with a geometrical shape that is easy to produce.
  • the cross-section of the conditioning device or of the conditioning area of the conditioning device that is engaged during conditioning may also be approximately diamond-shaped, so that a less sharp cross-section results for the same length profile, which can be used for conditioning in the case of axisymmetric design without consideration of a processing device.
  • the conditioning device can be composed of a multiplicity of subcomponents surrounded by a holding device, so that the contour of the conditioning device can be adjusted by arranging the subcomponents within or outside the engagement region during the conditioning device, and thus the contour of the groove to be achieved can be selected.
  • a large number of different groove shapes and widths can be processed and conditioned with a single conditioning device.
  • the partial components may consist of materials having different material properties, so that a further influence on the groove to be achieved by the conditioning device in the grinding wheel by means of the variation of the material of the sub-components is given.
  • the conditioning device may consist of a mineral material having a hardness suitable for conditioning the grinding wheel and having a suitable abrasive action therefor.
  • Fig. 1 shows a rod-shaped conditioning device 1, which is in engagement with a grinding wheel 2 to be conditioned.
  • the grinding wheel 2 has a circumferential, tapering to the grinding wheel center groove 3, which preferably has an approximately semicircular cross-section.
  • the grinding wheel 2 either consist entirely of a material suitable for machining abrasive material or the grinding wheel 2 may be made of a different material, such.
  • As metal or the like, and in an encircling recess include an embedded circumferential ring of appropriate, especially mineral abrasive material.
  • the rod-shaped conditioning device 1 In order to restore the profiling of the groove 3, to introduce another groove shape in the grinding wheel 2 or to change the sharpness of the groove 3, the rod-shaped conditioning device 1 is brought into engagement with the groove 3 with rotating grinding wheel 2.
  • the outer regions having only a very short length carry virtually no material, whereas the material removal increases with increasing length of the cross-section of the conditioning device 1.
  • the highest material removal in the middle of the groove 3 is effected by the center of the conditioning device 1 and achieved in the illustrated example, an approximately semicircular groove 3.
  • the lowest edge of the rod-shaped conditioning device 1 during machining also has a profile corresponding to the groove cross-section.
  • FIG. 2 shows the cross-section of a further rod-shaped conditioning device 1 according to the invention, in which both a longitudinal and a transverse symmetrical design with straight flanks is provided.
  • Fig. 3 shows a further embodiment in which the cross-section is formed symmetrically only with respect to the longitudinal axis, as well as in the cross-section of FIG. 4.
  • the conditioning 1 can be used both with forward pointed tip end, but also vice versa.
  • the conditioning device 1 is composed of a plurality of sub-components 4, which are surrounded by a holding device 5 at least partially.
  • Fig. 6 shows the article according to Fig. 5 in a perspective view.
  • all or even only certain partial components 4 from the holding device 5 can be used protrude and thus be engaged during conditioning.
  • both the overall cross section of the conditioning device 1 formed from the constituent parts 4 and the constituent parts 4 can have a wide variety of shapes.
  • FIG. 7 shows a further embodiment of a conditioning device 1 according to the invention which is in engagement with a grinding wheel 2 to be conditioned.
  • the conditioning device 1 has a semicircular disc-shaped form, which is formed by 180 ° rotation of an approximately trapezoidal cross-section about its wider edge on. When worn, the conditioning device 1 is tracked in the arrow direction.
