This paper investigates the application of electrochemical ballizing (ECB) in finishing holes which are produced by conventional machining processes. A special test rig has been designed where the electrolyte is pumped through an initial hole of hardened steel workpieces. The front of the tool is of spherical shape, and therefore the electrolyte distribution is regular. A computer implement model is proposed for accurately estimating the thickness of the removed workpiece surface. Experimental results have been found to agree with the estimated values. The surface roughness measurement and scanning electron microscopy indicate the improvement in the surface characteristics of holes.
