Glass Engraving Problems!


Recommended Posts

Recently we have been having problems with glass engraving where our cutter only goes over the surface and takes several attempts to engrave and sometimes not at all.

 

We have had 3 diamond cutters from Gravograph and 1 of eBay and the one off eBay only lasts 6 glasses and doesnt engrave on anything else.

 

And the ones from Gravograph last longer but the very first one was the best but the other 2 didnt last as long!

 

Any ideas why this is happening?

 

As we have been considering to stop engraving glass! - but we dont want to!

 

PLEASE HELP!!

Are you new to glass engraving or have you been doing it a while and only just encountered problems?

 

I presume you are using a feathertouch? Spraying lubricant on the glass? What sort of glass are you engraving? Pub Glasses? Crystal? Glass angled correctly in machine? Correct speed?

 

To be fair, you can get 'dudd' glass diamonds. I had one recently that was straight out of the packet and I used it on a piece of Royal Scot Crystal for it's first job. Normally you'd expect it to engrave like a dream, but it just wasn't having it. So I returned it and they exchanged it for me.

 

The fact that you've been through quite a few diamonds would suggest that the problem lies elsewhere though, I would have thought.

Also, check your spindle drive belt. If this is worn it will affect how the cutters spin in the spindle. An erratic or irregular spinning cutter will also affect your engraving.

Also try adjusting the "dwell time" (egg timer icon), so the cutter has chance to bite into the glass before moving around the text.

Check the Glasses for imperfections too.

Compound or drag diamonds will do the job, but will not last.

 

I use a faceted diamond, which lasts, and can then be re-lapped (sharpened).

Costs about £80, but works out cheaper overall.

 

Only needs very low pressure, especially at first.
