Diamond engraving

Postby beltramidave » Tue Nov 03, 2015 9:45 pm

For those of you wanting to try something different, get yourself a spring loaded diamond engraving bit. They work awesome for anything. I've done a few wine bottles and mirrors. Very simple, just find some clipart, the more detailed the better and get engraving.
Here is one I just finished. The picture doesn't do it justice.

If I may ask, what bit are you using and where did you get it? Really been thinking about one...

Thanks.

OK
You have me hooked.
I have been wanting to make a spring loaded engraving tool for a long time but have not found the time.
SO after seeing your work, I ordered one. Should be here in a couple of days.
I thought $345. was a little too much for me, so I found a hobby machinist that
makes batches of 25 at a price I could afford. His tool uses a 1/8" Dia. diamond
cutter while some models from other sources use a 1/4 inch Dia. cutter.
What Dia. is the cutter in your engraving tool?

What RPM do you run the engraving tool or do you just use it as a drag tool?
I noticed one company said theirs was tested at 30,000 RPM, one said not to
rotate the tool, another used 2,000 RPM and the one I ordered is tested at 5,000 RPM.
It is what it is!
Have a great day.

I found a few vendors that sell polycrystalline diamond bits:

http://www.toolstoday.com/c-442-cnc-dia ... -bits.aspx
http://www.carbideprocessors.com/router ... uter-bits/
http://www.amazon.com/Diamond-Drag-Engr ... -Machines/

In general the Diamond bits are pretty pricy, but if you do a lot especially in hard material (even a lot of MDF!), this type of bit will last a LOT longer.

IMHO, you might not want to replace all your bits, but might consider a new 'goto' bit if you use a small bull nose or flat end mill, one of these would last a long time even in heavy use. Still, I might keep a spare (even of carbide) on hand in case something breaks for some reason.

Just my thoughts.

... I started learning about these a few years ago when the owner of BuildYourCNC.com was complaining he was going through lots of carbide bits cutting MDF. I suggested these to him, he tried one and it lasted much longer than carbide bits with less wear and tool changes, and really helping his productivity. ... But then this was several years ago.

Hannah,

Great minds...

I just order one off of E bay today as well. Some were pricey, this one delivered to me for about $70. That I can live with.

Looking forward to doing cool things with it.

KLW
Which one did you get? Does it take the 1/8" or 1/4" diamond cutter?
What I ordered uses the 1/8" Dia. cutter and was from George Race (Race Consulting).
By the time I get the diamond engraving tool, it will be getting close to $ 70.
It is what it is!
Have a great day.
