Notes:
A simple, automated, fine-control, inexpensive, mechanical apparatus for coring thin samples is described. The apparatus consists of a motor-driven wheel attached to the feed handle of a microdrill press through an adjustable linkage that produces a peck drilling action. Using a Pb–Sn solder-tipped Cu or stainless steel core drill as a lapidary tool, cylindrical samples of ceramics, metals, and minerals with densities in the range 2.3–12.4 g/cm3 and as small as 250 μm in diam and 1.0 mm in length have been cored. Textures on the cored surface depend on sample type, grit size, core drill speed, etc., but surface height variations of 0.05–0.4 μm have been achieved with coring times in the range 1–6 h. © 1996 American Institute of Physics.
