The laser should be very good, however, price is out of our range.
The production, we are thinking of is very simple :
You put a thick tube (made of silver) inside the machine and from PC connected, you start a program and machine is cutting and drilling until the ring is made. Then the machine cut it off from tube and making another ring. The resulted ring is very nice (smooth) and difference from casted ring can be easily seen. Of course, we will use the machine for masterpieces and probably molds too, but above is our main idea.
Once, on Italy show I saw a machine (Italian), it was probably 5 axis (???), which was able to make things like cardan joint (small-model) and the results (rings) from these machine was perfect. The costs was about USD 100-110k. I am wondering, if there is something cheaper. Sorry for possible confusing, I am not familiar with CNC machines yet. Thank you for help.
