Airbag polishing process was recently developed by the British company Zeeko successful new method of precision machining surface. Working end of the polishing tool is coated with rubber balloon outside the abrasive layer film, polishing work, polishing tool airbag rotational movement is formed, the work on the airbag polishing tool relative feed motion (usually for three-axis workpiece feed motion) so that the entire surface of the workpiece can be polished. Polishing, while the need for tools airbag wobbles (wobble center of curvature center of the curved surface air bags), so that the abrasive wear uniform film layer. Because after the airbag inflator flexible tool that can automatically adapt to the curved shape of the workpiece, so that the same tool can be used for polishing of different curvature shape (but need similar) surface. This new method can be used for processing surface polishing aspheric surface rotation, it can also be used for processing free-form surfaces, highly polished surface quality.
