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?

What machine, power etc?

6040

tried Speed right down to 20

Power 100

60w tube

had scan gap right down to 0.001

run program multiple times

all other tool types engraving fine

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

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

Cool - will have to play

these are done at the following :

Speed 20

Power 100

Scan Gap 0.01

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