This attractive set of small dominoes was made from billet and bar stock 6061 aluminum using CNC production equipment. The shapes were first machined to size and then sent out for anodizing. An anodized finish on aluminum is extremely tough, and can be applied in a several colors. Finally, the parts were put back in the milling machine and a ball end mill was used to create the dots—or pips. Another tool is used to put the bevel on the edges, exposing the bright aluminum under the blue anodized finish.
