  • the hub has a central round opening.
  • the invention is specifically concerned with base bodies of injection molded material.
  • other sprayable material may be considered, for example, metal.
  • the invention is based on such consumable rotary disks, in which the base body is shaped differently than in a spraying process, such as while forming the base body of a metal sheet or of a non-injectable glass fiber reinforced plastic.
  • the material processing covering subject to abrasion is consumable, but also the basic body, which is expediently permanently connected to the material processing coating via a binder, in particular an adhesive.
  • the binding agent used may also be the binder of a material processing coating in which abrasive articles bonded in a binder are used.

  • the invention is primarily concerned with the application of the rotary disk as a grinding tool.
  • Modern such grinding tools should be operable with a maximum working speed of 80 m / s, which corresponds to a minimum breaking speed of 150 m / s.
  • the cost of the material of the body is high in comparison with that of the material processing coating and surpasses this even in rare cases.
  • This share of costs is extremely critical in the case of a mass-produced article, which is the consumable rotary disk according to the invention, for reasons of competition. Added to this is the effort involved in environmentally friendly recycling.
