... grit size) are used sequentially. The most common sequence of grit size for polishing composites is 120- followed by 320- and 600-grit papers. However, because of their short useful life, as mentioned previously, SiC papers are one of the most expensive options for rough and fine grinding. Figure 3.9a...

Since compression mounting pressures are great enough to produce twinning, cold-setting resins are preferred...

.... For successful grinding, therefore, the retained austenite content of a case-hardened surface is best kept low. Surface Oxides Surface oxides and internal oxidation, or the HTTP associated with it, can cause the wheel to become “loaded” and make grinding difficult. Fine, Well-Dispersed Spheroidized...
