In infrared spectroscopic analysis of the structures of protein crystals, a micro-flow cell made of single crystal calcium fluoride (CaF2) is needed. In this research, fly cutting of micro grooves on a CaF2 substrate was conducted using a single-crystal diamond tool. The effects of cutting direction, up/down cut, and tool rake angle on ductile-brittle transition of cutting behavior were investigated. Based on the experimental results and analysis, optimal cutting conditions were selected which enabled ductile machining of CaF2. As a result, a 10 μm deep micro-flow cell was successfully fabricated with surface roughness of 2.4 nmRa. The availability of the flow cell was confirmed by visible absorption spectroscopy of protein.
