Rotary engraving in glas with diamond drill bit
« on: March 12, 2018, 03:41:36 PM »
Hi Here is my first try , engraving a bottle with my rotary diamond drill bit.

It works first time, pouring few drops of water now and then

3 passes with a speed of 500 (full speed on the motor)

The connection bit hole to my motor is 3.1 , but my diamond drill is only 2.9 so is was a little shaky 

Using T2Laser from Zax everything works just fine  :)

Nice job, it's a lot harder than most people would imagine.

Very nice!  I agree with Zax. It is harder than it looks. Don’t know how I would have done it without T2Laser

Thanks for the comments
A wine bottle is not at plain smooth surface so I will se if I can trace the surface and adjust the z axes while the job is running

Have someone tried this ?

Thinking about it
I total forgot to set the bottle size in my T2Laser setup

But it came out okay
Pure luck I think

I have been laser etching wine glasses and currently do not have a z-axis. Limited to a relatively flat (vertical) region of the glass. Ready to add the z. Have stated on a software solution where I store various glass profiles and select at etch time. Would prefer a non-contact distance sensor and let the application do the figuring.

BTW - I suspect the laser is much more forgiving than a cutting tool. Do you do multiple passes?

I played with glass most of last summer. Wine bottles are hard

HI

Yes I do multiply passing , setting it to about 8 passes 3mm just to divide up, then when I think it looks okay I stop the cutting.
For this example it only had 3 passes.

I would all so like to make my ovn distance sensor so I can level out the curves there are in the bottle.

It could be nice if T2Laser could read a surface profile in x,y,z and do the math in that case we would be able to drill on every surfaces  :)

A surface profile scan would only require that it reads the z- distance censor in a x,y resolution by 1x1cm grid (maybe less 0,5x0,5cm grid)

Nice, I may try out this with my 2500mv laser with a black card behind the glass

I suspect the glass etches only on the side that has the energy absorbing  material. Getting the proper type and thickness of paint has been frustrating.
