Ultra-precision polishing is a processing method with extremely slow processing speed. It is not suitable for shape-forming processing. In recent years, due to the rapid development of short-wavelength optical components, OA instruments, and AV machines, higher requirements have been placed on the surface roughness of parts. So far, there is no better than ultra-precision polishing. A practical method, especially when the surface roughness of the parts is required to be better than 0.0lμm, this method is indispensable. For workpieces that require high shape accuracy, if the forced feed method is used for cutting or grinding , its shape accuracy will be directly affected by the feed and positioning accuracy of the machine tool, so as to achieve the reaction, and the resulting processing effect, there are the same tiny concave parts on the surface of the workpiece, in general, only large ripples can be obtained. s surface.
