Old Question - New Twist
Hi Guys,
I see that the "how much power does it take" question is pretty beat to death here. Here's my version
I am looking to laser engrave mild and high carbon steel that has been black oxided and 7075 aluminum that has been black anodized.
Here's the twist!
These are Firearm parts and therefore need to be engraved a minimum of .003 deep to satisfy the ATF. I know a 60W or so CW CO2 laser will engrave the coatings, but will a 180 or 200W get me the .003 depth I need? I can multi-pass it if need be, I'm not looking for hi throughput so time is not an issue. I'm just tired of tying up a 100K machine tool to do a laser job.
I have seen some smaller Yags on Ebay, around 40-50W will these do the job? Just real leary about buying a used laser that I can't get service for.
Thanks for the help!
