Metal Etching -- looking for the right terminology
I have seen (held in my hands, actually), metal parts that are made by
etching thin steel with acid (presumably after printing on a resist). It's great stuff for making optical stops, encoder wheels, and other things where the worst that the metal has to resist is a stream of photons smacking into it. The steel in question appears to be either stainless steel or tin plate, dead soft, and is maybe 5 or 10 mils thick. What's the processing called in the industry? What sort of shop should I direct someone to look for in their yellow pages or their Thomas Register? What sort accuracies can one expect, and setup costs, and fabrication costs? -- My liberal friends think I'm a conservative kook. My conservative friends think I'm a liberal kook. Why am I not happy that they have found common ground? Tim Wescott, Communications, Control, Circuits & Software http://www.wescottdesign.com |
