Not only the new method achieves better mirror quality with bigger diamond in diameter quickly  but also because of the fixed motion between the abrasive and workpiece and it will be good for surface finishing. During experiment  material removal characteristic which is on SiC under certain rotation speed and pressure by W7  W5  W3.5  W1.5 pellets has been tested. Through those removal curves  we come to a conclusion that the technology not only has a higher removal rate  but also has much more stability. In addition  the surface roughness experiment is mentioned. In the first stage  we achieved a mirror with surface roughness 42.758nm rms with W7 pellets. The surface roughness is descending as we change pellets with smaller diamond in diameter . At the end of experiment  a smooth surface with roughness 1.591nm rms has been achieved after using W1.5 pellets. Experiment results indicate that the technology which manufactures SiC reflecting mirror with fixed abrasive is able to replace the traditional slurry abrasive completely in certain finishing phase and also has a great foreground in application. 2009 SPIE.   Beneficial effects of Co(2+) on co-electrodeposited Ni-SiC nanocomposite coating 期刊论文 Transactions of Nonferrous Metals Society of China, 2009, 卷号: 19, 期号: 1, 页码: 119-124 X.

However  polishing large SiC aspherical mirrors is difficult compared to other materials such as fused silica or Zerodu. In addition  surface roughness of the polished SiC mirrors is limited by the defects of the materials and needs to be improved by means of surface coating technique. This paper introduces the current progress of large SiC aspherical mirrors manufacturing and testing in CIOMP. In particular  the procedures of making large off-axis aspherical mirrors were discussed in detail. A proprietary computer controlled optical surfacing (CCOS) technique was utilized to grind and polish the mirrors and the computer aided null test was used to measure the surface figure. As results  a 600mm class off-axis SiC aspherical mirrors was demonstrated with figure error less than 13nm rms.
