Guidelines for Wafering Cutting Various Materials

Most wafer cutting is done at speeds between 50 rpm and 5000 rpm with loads varying from 10-1000 grams.Generally, harder specimens are cut at higher loads and speeds (e.g, ceramics and minerals) and more brittle specimens are cut at lower loads and speeds (e.g, electronic silicon substrates). It is interesting to note that the cutting efficiency for sectioning hard/tough ceramics improves at higher speeds and higher loads.
