Abstract: In a process for producing hard grinding elements, a synthetic resin having a dynamic viscosity of less than 10 mPa.s is used as the binder. By adding this binder, the mixture of abrasive grains, binders, and fillers is highly thixotropic and can easily be liquefied by vibration and can be filled into a casting mold having almost any desired shape where, due to the addition of a radical forming starter system to the mixture, the synthetic resin is polymerized. Methacrylic acid esters or vinyl acetates are particularly applicable as monomers for the binder.

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.
