1. Diamond tools for precision and micro-machining. Diamond is used very often as tool material for ultra-precision and micro-machining. The reason for this is the very high dimensional stability of diamond due to its extreme hardness. In ultra-precision machining as well as in micro-machining very small depths of cut ( ae) are used, which ...
A high-precision hybrid micro fabrication technique that combines micro co-deposition, micro w-EDM and a technique for micro grinding is proposed, and its usefulness in generating microgrooves on optical glass is verified productively in this study. An extremely thin diamond wheel-tool is fabricated by a micro co-deposition process.
Current demands for flexible, individual microstructures in high quality result in high requirements for micro tools. As the tool size defines the minimum structure size, ultra-small tools are needed. To achieve tool diameters of 50 µm and lower, we investigate the complete manufacturing chain of micro machining. From the development of the …
