This article presents the grinding tools designed to serve hybrid machining process – ultrasonic wheel vibration assisted grinding. It describes possibilities of using of different abrasives, grinding wheel clamping systems and holders with ultrasonic oscillation inductor. Realization of Ultrasonic Assisted Grinding (UAG) process is possible on machines with special design. Most machine tools are manufactured on the basis of conventional ones and are retrofitted with ultrasonic vibration system. There are two types of tool holders designed for this machine tool: holders for hybrid machining processes (ultrasonic actors) and holders for conventional processes. Each type of tool holder is fixed to the spindle with hollow taper shank. The tools are attached to the ultrasonic actors by screw and positioned on arbor, or by the collets. For the UAG process tools made of various abrasives are applicable. Binding material, the concentration of abrasive grains and their size may differ. It is possible to use diamond or cubic boron nitride tools and also tools made of conventional abrasives. Ultrasonic Assisted Grinding is a novelty in the field of manufacturing techniques. It is necessary to conduct detailed investigations of this process. The factors that have a significant impact on the UAG results for different materials, the oscillatory motion parameters in relation tool or workpiece as well as on the dressing tool should be investigated.
