Abstract
A method of polishing an object is disclosed. In one embodiment, the method comprises the steps of creating a polishing zone within a magnetorheological fluid; determining the characteristics of the contact between the object and the polishing zone necessary to polish the object; controlling the consistency of the fluid in the polishing zone; bringing the object into contact with the polishing zone of the fluid; and moving at least one of said object and said fluid with respect to the other. Also disclosed is a polishing device. In one embodiment, the device comprises a magnetorheological fluid, a means for inducing a magnetic field, and a means for displacing the object to be polished or the means for inducing a magnetic field relative to one another
