very small holes in .300MM tungstem
very small holes in .300MM tungstem
(OP)
I need to put several small holes in a piece of .300mm thick X 1.5mm dia tungsten. The holes need to be arranged in a succession of sizes from .005mm - .020mm dia. I have tried laser cutting but the edges are very rough and I need these to be a perfect circle. All of my EDM vendors say that they cant go that thick with a .005mm hole and still be precise.
What other methods are available?

One way to get round holes with a square edge is to make the best hole you can and then grind or grind and diamond lap the part. This works quite well as in a lot of holes the entrance is quit rough but the hole them gets very good at a shallow depth.
