Need some Help Engraving a Brass Plaque

[Bronco78th]

Hi All

 

Im hoping one of you could help me.

 

Basically ive recently taken over the responsibility of engraving for our company since our previous engraver has left. Im finding it jolly good fun as it co-insides with my artistic side.

 

However certain things I am having to work out as I go as both myself and the previous engraver are both self taught apart from abit of tuition from an engineer when we first got our machine and finally ive got abit stuck.

 

I’m having a problem engraving a brass plaque 0.5mm thick as the normal hard metal cutter won’t cut deep enough. So I want to use a Tungsten Carbide tip (semi circular nib).

 

The problem im having is a simply don’t know how to properly set a consistent depth since the drill bit has no spring just a nosecone.

I figured the depth must be set in Surelab Pro (v7.1) somewhere but I just don’t know what setting(s) im looking for or what to change.

 

Helpfully our previous engraver didn’t cover this with me in the handover and has simply put on the notes to 'Set the machine as per manual'….which manual is that?!?

 

Any tutorials or advise on how to cut a slightly deeper depth into Brass using Surlab Pro and a Rotation S Machine.

 

Thanks in advance.

Regards,

John

I wouldn't cut into 0.5mm brass, i would only diamond drag.

To cut in and infill I would use at least 1.5mm but usually 2mm or 3mm as you should be cutting in about 0.3mm deep so you can fill with paint.

Cheers for the advise fellas.

 

Michael - Just using the drag had the most desirable result on my now exstremeily battered test peice - however I was under the impression that doing Brass with a diamond drag would blunt the tip exstremeily fast....hence why I didn't try it. Is My assumption wrong?

I would think being only 0.5mm thick it's jewellers brass, your diamond should be fine and depending on what your engraving and how many of them, a diamond should still last months.

Is it definitely brass and not gold aluminium?

Cheers for that.

 

Yep definately Brass...we also do Gold Aluminium plaques....Its the weight that gives them away!

 

The Brass are generally saved for the more desirable items...in this case Decanter Sets.
