Brass plate laser cut

Discussion

Hi guys,

Has any of you lasercut a 0.5mm brass plate with machine in the space?
Any experience? Is it possible? The plate i found is laser cut compatible.

Thanks,

Hi. My quick research suggests that you cannot. Fibre lasers can, CO2 lasers can’t.
If you have further details on “laser cut compatible” we can comment further.

Hi Brendon,

Not further specifics on the product… So you are probably right.
According to our machine i can engrave metal, right? So probably i’ll do that and cut with scissors following the contour ( old style)

Thanks,
Federico

Apologies… The brass is 0.127mm not 0.5mm
Does it change anything?
I can still engrave it, right?

Thanks
Federico

Hi Federico, :smiley: a plasma cutter is usually for metal, yes you can engrave but you must first paint it (I engraved some blanks to make a pirate coin game puzzle ) If you paint it in black you will be able to see it better, DO NOT engrave without painting the sheet as this will damage the laser head which will be very costly to repair . I hope this is of some help to you.Keep well . Brian D=

The space machine can engrave anodised aluminium, if you are looking to engrave brass/stainless steel/titanium etc. you are better of using a marking additive before you put the metal under the laser. The mark produced varies from a grey to pure black depending on the settings and metals used. I have some Cermark spray personally but I believe @petra had some of the liquid form at the space some time ago… below is an example of some parking I did on a stainless steel part I was working on:

Thanks guys!
I’m not going to do anything immediately, I’ll check the best way to mask the plate first.

Thanks,
Federico

I’ve had some success spraying on brass with black paint, lasering away selected areas and then etching with ferric chloride.
