Hydrodynamic polishing (HDP) process is a new method for polishing of the hard materials. In HDP, shear stress is used uniquely for removing material. The material removal takes place with hydrodynamic phenomenon and shear stress. The process has proved itself for any hard material and importantly without abrasive action. Lot of researchers has shown ability of the process. In this paper experimental work is presented. Experiments were conducted steel plates with rubber as tool material and alumina as abrasive. Time of polishing and spindle speed is measured and optimum time of polishing and spindle speed is decided. In this paper different parameters and their effect in HDP is also analyzed.
