Abstract
An elastic grinding element for form-true grinding including a supporting layer of elastomer material and an adhesive grit layer bound to the supporting layer and having an active grinding surface made of a hardened mixture of binder and abrasive grit. The process for making the grinding element includes providing a mold having a shape constructed to produce a desired shape for the grinding element, putting the mixture of binder and abrasive grit and the elastomer material in the mold, and accelerating the mixture of binder and abrasive grit and the elastomer material while in the mold.

A process for producing an elastic grinding element for form-true grinding, wherein the element includes a supporting layer of elastomer material and an abrasive grit layer bound to the supporting layer and having an active grinding surface made of a hardened mixture of binder and abrasive grit, said process comprising:
- providing a mold having a shape constructed to produce a desired shape for the grinding element;
- putting the mixture of binder and abrasive grit and the elastomer material into the mold;
- providing a rotating system;
- disposing the mold in the rotating system;
- and
- subjecting the mold with the mixture of binder and abrasive grit and the elastomer material therein to a centrifugal force via the rotating system.
A process for producing an elastic grinding element for form-true grinding, wherein the element includes a supporting layer of elastomer material and an abrasive grit layer bound to the supporting layer and having an active grinding surface made of a hardened mixture of binder and abrasive grit, said process comprising:
- providing an elastic planar mold having a shape constructed to produce a desired shape for the grinding element;
- prefabricating the abrasive grit layer with an active grinding surface by putting a mixture of binder and abrasive grit in the elastic planar mold;
- rolling the elastic planar mold into a ring shape with the abrasive grit layer disposed therein;
- and
- providing the prefabricated abrasive grit layer with a ring-shaped carrier layer of elastomer material.
A process for producing an elastic grinding element for form-true grinding, wherein the element includes a supporting layer of elastomer material and an abrasive grit layer bound to the supporting layer and having an active grinding surface made of a hardened mixture of binder and abrasive grit, said process comprising:
- providing a rigid planar mold having a shape constructed to produce a desired shape for the grinding element;
- prefabricating the abrasive grit layer with an active grinding surface by putting a mixture of binder and abrasive grit in the rigid planar mold and bonding a carrier material to the abrasive grit layer in the rigid planar mold;
- removing the abrasive grit layer along with the carrier material from the rigid planar mold and placing it into a ring mold;
- and
- providing the prefabricated abrasive grit layer with a ring-shaped carrier layer of elastomer material.
