flavor flav said:tried this already.....4 different suppliers.. no one can cet it right.. and after spending so much $$$$ and time, i gave up. they don't understand it must be 1:1 and they cannot get the geometry right. the genuine CG is flared up on the end, and apparently this curve is extremely hard to duplicate. if anyone wants to buy this part and do the same.....go for it!
When you say suppliers, do you mean in China or USA? Also, you may not be going to the right people. Micro machining or Micro CNC is a different field than most of your CNC factories. I doubt the Chinese care too much about 1:1 because they are thinking of overall cost. Where as some of the companies who deal strictly with micro machining and scanning understand the need for exact tolerances.
If you really want to talk about it, PM me.
