Micro milling

Quantifying the effect of surface roughness or morphology is difficult, however. Surface preparations that provide different degrees of surface roughness also usually produce surfaces that have different oxide thicknesses and mechanical properties, different compositions, or different contaminant levels. The problem of separation of these variables was circumvented in a recent study [52] by using a modified microtome as a micro milling machine to produce repeatable, well-characterized micron-sized patterns on clad 2024-T3 aluminum adherends. Fig. 2 shows the sawtooth profile created by this process. 

The slit is made by pEDM the micro channels are etched in the plate [1-3]. The gas chamber and the two diffusers are made by pEDM. The heat exchange channels are manufactured by micro milling. 

Polymer Synthesis. A solution of 30 mL of (meth)acrylic acid, 5 mol% triethyleneglycol di(meth)acrylate and 0.3 g K2S20g in 300 mL deionized water was stirred and heated at 95°C under N2 for two hours. The gelatinous mass was vacuum dried at 50°C for 48 hours. The polymer was then ground in a Micro-Mill. The portion passing through a 40 mesh screen (<425m) was extracted three times with 80-90°C water and then redried. 

Micro milling was applied frequently in many early applications of micro structuring. Microfabrication of the parallel channels was performed by micro milling of metal tapes at the Karlsruhe Research Center (Forschungszentrum Karlsruhe) [138], In the case of aluminum alloys, ground-in monocrystalline diamonds were used [139], In the case of iron alloys, ceramic micro tools have to be used owing to the incompatibility of diamonds with that material [44], It is certainly a useful tool for experimental work and rapid prototyping, but not a choice with respect to future mass production. 

MICROS mill can operate both in batch and continuous regime vertical and horizontal types of working vessel arrangement are possible. Ring roll mills were successfully used for mechanochemical synthesis of Ca3(P04)2-nH20 from Ca(H2P04) H20 and Ca(OH)2 [12].

The samples, taken at a depth of >1 mm from the surfaces of the cured specimens, were broken into pieces. The pieces is ready for ESEM observation without any treatment. However, for the XRD measurement, the pieces were cleaned with absolute alcohol and then stored in the alcohol for at least 6 days for hydration interruption. Before tested, the pieces were removed from the alcohol and vacuum-oven-dried at 40°C until the mass becomes constant. The dried pieces were grinded with FRISCH Puluerisette 7 Planetary Micro Mill into powder.
