    Your EDM machine would have to have that capability, it's not something all EDM machines can do, on the older machines it was a add on extra, check your manual to see if your machine has mirror finishing

    Re: looking for a mirror finish on my EDM sinker

    Our company just bought this same machine and nobody knows how to operate it. The manual is very basic about setup and the price for someone from the company to come in for training is too expensive for our small shop. D you have any information or know of any videos that would be helpful? I would appreciate any help.
