Definitions

  • the invention relates to a method for gluing abrasive material, in particular abrasive belt or abrasive belt sections on an abrasive body, preferably a grinding wheel or the like.
  • grinding bodies are used whose surfaces touching the workpiece to be machined, usually the peripheral surface, are covered or coated with sanding belt.
  • the abrasive belt is glued with the linen or paper side directly onto the assigned outer surface of the abrasive body, e.g. using a contact adhesive.
  • sections from an abrasive belt can also be glued to the grinding wheel, in particular if the surface of the grinding wheel to be glued is profiled, e.g. to be able to process a profiled wooden surface.
  • the used abrasive belt must be removed from the abrasive body and replaced with a new abrasive belt.
  • the grinding wheels are made of elastic material, such as rubber or cork, and with such materials it can happen that, when the used grinding belt is torn off in areas in which the adhesive is not completely dissolved, pieces are torn out of the contact surface of the grinding wheel, as a result of which the grinding wheel becomes unusable.
  • the previously used method for removing used abrasive belts from the grinding wheels also has the disadvantage that relatively aggressive solvents are required, the processing of which is unpleasant or even harmful to health.
  • the material of the grinding wheel can also be attacked and destroyed by an aggressive solvent.
  • the predetermined constant profile cut into the abrasive body can be changed by the repeated, constant rubbing off of adhesive residues, so that the abrasive body also becomes unusable for machining profiles.
  • the invention has for its object to find a method for gluing abrasive material to a rotating grinding wheel, which allows easier removal of a used grinding belt from the grinding wheel.
  • a separating layer made of solvent-resistant material is applied to at least one of the two mutual contact surfaces of the abrasive belt and the abrasive body.
  • the separating layer advantageously prevents direct contact of the adhesive with the contact surfaces to be bonded.
  • a used sanding belt e.g. To remove from a grinding wheel, it is sufficient to dissolve the interface.
  • the separating layer advantageously has the property that it can be easily dissolved in a relatively mild solvent if the grinding body is immersed in a solvent with the grinding belt. It is therefore no longer necessary to use aggressive solvents to dissolve the adhesive layer. Adhesive residues can no longer stick to the contact surfaces as soon as the separating layer is dissolved.
  • the separating layer is preferably applied to the contact surface of the grinding body, so that when this separating layer has been dissolved by the solvent, the grinding belt with the adhesive residues adhering to its contact surface can be removed together.
  • an easily releasable separating layer is applied to the contact surface of the grinding body and that a separating layer made of material which is relatively resistant to the same solvent is applied to the contact surface of the grinding belt.
  • the arrangement of adhesives of different solubility results in a connection between the grinding body and the grinding belt with high strength.
  • the use of a vinyl resin is preferred as the adhesive see.
  • a polyurethane resin can also be used.
  • a mixture of the two resins is of course also possible.
  • a resin as an adhesive is preferably suitable. Of course, other adhesives can also be used. Only the properties of the adhesive that can be used as a separating layer are important. It must be highly flexible, temperature-resistant and have favorable adhesive properties in order to be able to make firm connections with the contact surfaces of both the grinding body and the grinding belt.
  • connection properties with the adhesive to be used which is preferably a contact adhesive.
  • the adhesive that can be used as a release layer should dry relatively quickly after application.
  • Another important property that the adhesive used as a release layer should fulfill is its ability to dissolve in a solvent which is not harmful to health, is not aggressive and is uncomplicated to work with.
  • Possible residues of adhesive can then be removed by a light Rubbing can be removed from the grinding wheel without damaging it.
  • a relatively high adhesive strength of the connection of the grinding belt to the grinding body is achieved.
  • alcohol in particular alcohol
  • a material for the separating layer according to the invention that dissolves in water would also be possible.
  • water has the disadvantage that metallic parts of the grinding wheel can be attacked by corrosion. This is not the case with alcohol.
  • the measures according to the invention have the advantage that they can be used with all abrasive bodies made of cork, rubber, metal, wood or the like materials which are provided with bonded abrasive material.
  • abrasive bodies made of cork, rubber, metal, wood or the like materials which are provided with bonded abrasive material.
  • the grinding belt can easily be detached from the grinding body. Laborious and time-consuming preparation of the grinding wheels before a new grinding belt can be glued on is not necessary, so that the grinding wheels to be refurbished can be used again in the shortest possible time, e.g. in a grinding machine.
  • Fig. 2 shows a section through a grinding wheel, the circumference, and thus also the contact surface 4, is profiled, so that the grinding belt 8 is arranged with the profile contour.
  • the separating layer formed from adhesive as well as the adhesive layer and the mutual contact surfaces are again provided with the same reference numbers as in FIG. 1.
