I beleive they sell a paint or some king of stick on coating to stop
the reflection. Have him check with his supplier.

I realize this has probably been discussed ad nauseum, but Ididn't find
much
in the archives, not that I got too thorough in searching them.

We are looking at purchasing a laser for cutting flat sheets. I am
wondering how tough the laser cut edge is on milling cutters. Some of
the
items we are considering cutting have shoulders, chamfers, or the like
machined on some of the edges.
We will be cutting A36 steel about 95% of the time, there will be some
6061
aluminum thrown in, but I can't see that being much of a problem

We currently have a plasma machine and we don't even bother attempting
to
machine those edges. It is just too tough on the cutters.

Is the laser going to be the same, or is it somewhat better?

Thanks in advance for the help.

I've machined laser cut 304 SS, without any difficulty.

The guy that does my laser cutting won't do aluminum though. He says it is
too reflective and ruins his mirrors.

Thank You,
Randy

It is not the shiny surface of the aluminum that is the problem. It is the
aluminum vapor that is very reflective.
