Diamond tool wear mechanism is more complex, can be divided into macro-and
micro-abrasion wear, the edge polishing pads former mainly mechanical wear, which is dominated by
thermal chemical wear. Diamond grinding tool breakage common form for the
former flank wear, flank wear and edge chipping. In single crystal diamond tool
sharpening process, requires the diamond blade wear to the grinding tool to meet the
requirements, but if the wear generated may damage not have a good grinding
before the flank. The edge cracking (i.e. chipping) is on the edge of the local
stress exceeds the capacity of the diamond cutting tool occurs, generally the
diamond crystal (111) cleavage plane of the micro-damage caused. In the ultra-
precision machining, diamond tool edge radius of the cutting edge is relatively
small, which itself is hard and brittle materials, and because of its
anisotropy and (111) surfaces prone to cleavage, with the concrete core bits vibration of the tool
blade and grinding wheel grit the mouth of the impact of the role, it is often
accompanied produce chipping.
