But recalling the nanometre-scale accuracy reached routinely today in the workshop and the high degree of geometric flexibility offered by multi-axis machines and ion beam contouring of diamond tools, one rather has the impression that the development of diamond machining has achieved maturity. This is not quite true for precision grinding.

The 5–10 μm-grit tool had the longest tool life at a feed rate of 2.4 mm/min with a grinding speed of 11.3 m/min and the longest tool life of the 5–10 μm-girt tool, 550–650 mm, was twice as long as that of the 2–4 μm-grit tool. We applied our tools to manufacturing micro-devices and fabricated a few kinds of micro-channels which can ...

The micromill-grinding tool is a compound tool that has both micromilling and microgrinding abilities. Local electroplating was employed to fabricate micromill-grinding tools with CBN abrasive. The grits topography of the flank face was measured, and the graphical investigation was carried out to evaluate the distribution of the grits. It is found that the coatings were well electroplated …

Micro grinding with a poly crystalline diamond (PCD) tool is one of the promising approaches for fabricating a micro mold on difficult-to-cut materials. As the process can also achieve good surface integrity without additional finishing processes, it could shorten total processing time and reduce total energy and resource impact. Modeling of micro grinding is necessary to understand the …
