Engraving aluminium

Post by Highlander » Wed Sep 11, 2019 10:38 am

Problem trying to engrave what i think are aluminium tools.

No matter how slow i run it or how many times i run the program it hardly marks the surface.

I've been engraving other tools no problem.

Any ideas?

Unless the aluminium is anodised or treated with cermark type fluid it won't engrave metal.

Were the other tools coated?

Other tools are all hardened steel.

am i easier having them milled?

I was worried the laser would melt them to start with but i can hardly mark them :D

Can you show pictures of the hardened steel?

Normally these power CO2 lasers will not mark metal without the magic liquid.

I have a fibre laser that marks metal - but if you need a deep engrave then milling may be easier for you ;)

Mostly pliers, spanners, hammers etc

we've been using it to mark tools for a few years now, only real problem we have is Channelock Pliers that need doing 2 or 3 times

Thanks - I suspect it is a heat treatment more than actual ablating but cool nonetheless ;)
