Just how much jewelry do you make? Do you have a catalog?

This is a sideline hobby that my partner and I hope to turn into a business.

 

I will post a website in my profile when it all gets going.

 

We plan to have an online store, yes.

 

Hopefully it will open early next year.

 

Making custom, one of a kind rings and other jewelry.

 

Using Mastercam is going to be a huge plus I am thinking since it has ART and I already know my way around the software.

 

4th axis was kinda hard for me, but I am getting the hang of it, due mostly to all the great support I have gotten from this Forum....

Oh! Well, that is one thing I learned today. I now have a name for that sharp pointy bit that will cut the stuffin out of ya.

LOL ya, I think that name came from an old penographer that taught me back in the 70's.

 

They used to cut all those coin dies with a freehand penograph and a handfull of stickles in the old days before the CNC....

 

Your model would be huge and when it scaled down the error would be almost null...

Keep me posted on your progress. I looks like you've got the machine to go far with....

 

I too have learned a lot here. And know I need to learn a lot more......

Good luck

I cut the gold with a 4 flute deckel cutter that I ground at 15 deg / 7.5 side with a .002 tip and only went down .5 mm /.020" deep over all...still have the tiny chips in a bag

and the wife only wears it out to special occasions.

Was a one time thing for a family heirloom for the my wife.

I have not done any on gold yet. All of mine so far has been lost wax casting.

 

Wow making your own cutters is way above my skill level. What kind of jigs did you use to hold the bracelet? I want to do some stone carving but I will have to graduate to that also.....

I made a gold wedding band one time on a wire edm. It was a scallop design for a store. They gave 3 plates of gold about .1 thick and I made the design in all 3 plates they then took the center plate and rotated it to be off to the other scallops and then silver soldered it all together. It turned out pretty slick.

 

Good place for endmills top quality stuff at Harvey.

All the stuff we do is lost wax.

 

There is too much loss involved in machining directly on the silver and gold.

 

So to do a braclet, I would just let the wax block be its own jig and them bend it once it's cast.

 

You can flip the wax block over and push it up against stops on the mill table and leave a thin piece of flash around the outside.

 

After the top and bottom configurations are machined, I will do a paramater cut and drop the braclet out of the block. Then handwork any areas that need it and make the investment mold.

Okay.... I can do that. Whole lot easier than I was trying to make it.

 

Thanks

Y/W.... glad to see someone else using Mastercam for jewelry..

 

 

Good luck and merry Christmas

[cm-horses]

And the same back at you.

 

I will have to get busy and put some of the things I have done with MC on my web site.

 

Thanks again for all of the help. After the first of the year I probably will be yelling Help again!

 

Merry Christmas to all.
