Article Preview

In the paper, the ELID grinding is, first of all, adopted to pre-process the surface of WC-Co cemented carbide, obtaining the precision machined surface, Ra=18nm.Then the mechanical polishing process is implemented. When conducting mechanical polishing, the polishing liquid with W1 diamond grits is used to process the surface about 100 minutes after ELID grinding, aiming to achieve rapid removal. About 100 minutes again, the ultra-precision surface, Ra=4nm, is obtained, by the mechanical polishing ,using the polishing liquid with W0.5 diamond grits .Meanwhile, on the surface roughness effects of abrasive type, grain size, polishing liquid solvents, polishing pressure, polishing machining time and so on, are researched in-depth for the process of mechanical polishing.
