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.
