Definitions

  • the innovation concerns a grinding wheel that is attached to a holder so that it can rotate or be fixed.
  • Rotatable grinding wheels of this type are made in one piece and are used, for example, when machining hard, metallic sealing seats in fittings.
  • the disadvantages of grinding wheels of this type are that after the abrasive has worn out, the entire grinding wheel must first be carefully removed and then disposed of in its entirety.
  • the innovation is based on the task of creating a grinding wheel of the type described in the introduction, which is formed in two parts from a grinding wheel base body and a releasably connected grinding wheel attachment provided with a grinding surface, which is centered on the grinding wheel base body and whose material thickness is at most 50% of the maximum material thickness of the Grinding wheel base body is.
  • This grinding wheel attachment is easy to replace, so that the grinding wheel as a whole no longer has to be disposed of. Due to the significantly lower material consumption, this leads to lower production and disposal costs. The costs for assembly and disassembly are very low.
  • the base of the grinding wheel can be coated with sandpaper and can therefore also be used for grinding alone. This means that a spare grinding wheel is always available at the processing location.
  • the grinding wheel can be designed in such a way that the grinding wheel attachment is provided with an abrasive coating or can be equipped with sanding paper and can therefore be used for a wide variety of grinding work.
  • the grinding wheel can be designed such that a bayonet or clamp closure is provided as the fastening device. Such closures allow a quick replacement of the grinding wheel attachment.
  • the grinding wheel can be designed such that the fastening device is designed for left- and right-handed grinding and can therefore be used for all common systems.
  • the grinding wheel can be designed in such a way that only one grinding wheel is used for grinding processing, which allows targeted machining of small objects.
  • the grinding wheel can be designed such that a plurality of fixed or rotating grinding wheels are connected to one another via a multi-armed device, rotating about a common axis, are used for grinding. This is particularly useful for the uniform processing of large areas.
  • the grinding wheel can be designed in such a way that the grinding wheel attachment consists of different materials, preferably metal.
  • the grinding wheel can be designed such that the material thickness of the grinding wheel attachment is at most 30% of the maximum material thickness of the main grinding wheel body. This significantly reduces the costs of manufacture and disposal.
  • Fig. 1 Grinding wheel base and grinding wheel attachment with fastening device.
  • Fig. 2 Grinding wheel attachment
  • FIG. 1 shows a grinding wheel attachment 3 attached to a grinding wheel base body 1 by means of a bayonet lock 4, the rivet 5 of the bayonet locking mechanism Ses 4 is designed such that a perfect grinding is guaranteed even with the grinding wheel base body 1 which can be equipped with a grinding surface.
  • FIG. 2 shows a grinding wheel attachment 3 with a grinding surface 2 and three bores 6 for attachment to the basic grinding wheel body 1 by means of a bayonet lock.

Abstract

Disque de ponçage fixé rotatif ou fixe sur un dispositif de retenue, qui est constitué de deux parties, à savoir un corps (1) et un élément rapporté (3) doté d'une surface (2) de ponçage et relié amovible à ce corps. L'épaisseur de la matière de l'élément rapporté (3) centré sur le corps (1) est égale à 50 % au plus de l'épaisseur maximale de la matière du corps (1). Ainsi, il est facile de remplacer un élément rapporté (3) usé. Le disque de ponçage ne doit plus être jeté dans son intégralité, ce qui entraîne une baisse du coût de fabrication ainsi que d'élimination, en raison de la quantité considérablement plus faible de matière utilisée.
