I mounted the copper disk and TCXO up on my mill and started cutting. I probably could have made slightly faster progress if I swapped the 250 μm endmill out with a bigger one, say a 1.5 mm, but the sample was small enough I didn’t want to bother messing around with collets and wrenches to change tools. The machining only took a couple of minutes, making very slow gentle passes a few tens of μm deep before the edge looked to be about ready to punch through.
