Abstract: A process for improving the grinding performance of a porous ceramic or plastic bound grinding or honing body, using the steps of obtaining a conventionally produced porous ceramic or plastic bound grinding or honing body, and filling the pore spaces of the body at least in part with at least one metal soap.

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: A grinding tool for metal machining which is provided with matrix-bonded abrasive grains, the hardness of the matrix varying over the grinding area, along which the workpiece moves in a single operation during its passage.

Abstract: Abrasive grains rigidly bonded to each other form aggregates which are dispersed in a resilient matrix of an abrasive wheel so that the aggregates do not significantly interfere with each other's individual movement under grinding stresses against the resilient restraint of the matrix. The wheels remove metal from a workpiece much faster and lose less abrasive material than corresponding wheels in which the same abrasive particles are individually embedded in the same matrix.
