Cant dig ,can cut?

Here's a few more pretty's to ooh over. 15.4ct Antique rectangle green tourm. 15.80ct Pink and green tourmaline emerald cut. Green tourms.

Now you have my attention, beautiful stones.

I like the step cut green..

I like them all nice work how long dose it take for the more complex cut compared to simple cut

Wow, they look amazing.
Good stuff mate

Fast cutting system. 104 facets x 3 minites per facet for 3 processes = about 5 hours on the large green tourm.

I am not a stone cutter and know only what I have read about cutting , but your fast cutting system intrigues me, do you run into problems with contamination between the different grades of cut ? what steps do you take to avoid it ?

The outer rim is 1200 sintered copper and is water cooled which flushes away the swarf.
the next section(the middle) is 3000 mesh compound applied to in this case a zinc lap.
the centre is a special alloy that's low scratch high polishing finish on 50,000 to 200,000 mesh.
200,000 for sapphire.
If you wipe and inspect your facet as you would anyway then no cross contamination will occur.
When a senior moment occurs then the lap is wiped clean with spray dregreaser and fresh compound
is applied.

Who is making the fast cutting laps? - I'm interested

I am Dughug.
Have a look at my blog http://gemcutters.blogspot.com.au/
Im in the final stages of tooling up but have been selling for a month now. A few minor tweeks to machines and making systems to make the system so to speak.
I just finished my flat lapping system with an auto grit feed and osciiation attachment.
