6.1. Sandblasting
Almost all of the framing movement parts at NOMOS are allowed to ride this carousel without having to queue: movement plates, three-quarter plates, balance cocks, and bridges. While they do, the parts also get a good sandblasting. But in a very gentle way—because it's not sand, but the finest bronze filings. This evens out the many different surface structures that result from the machining process. Not only does it look better, this also helps with optical measurement methods, creates an even surface for polishing, and smoothes some of the edges. And it's fascinating to watch!
