I would agree that this is a EDM job for sure. One thing to keep in mind that most people starting out is that you should buy a machine that fits the job size. I see alot of people buy machines that are way to big for the job it is bought for and later trade in for a machine with a smaller foot print and cut area. I agree that submerged should be used and get a macnine that is still being made today. Just cause you can get a deal doesnt mean it is a deal when it is sitting there needing parts and there is no one to buy the parts from.
Smaller Dia wire means slower speeds but higher finish and tighter tolerance. (In the US most people use .01-.012 dia for speed and in japan they use .008-.004 and go as low as .0005 dia). Most machines you can get away with 2 cuts. If the tolerance is .002 that is wide open for EDM but the surface finish requires the second pass. I know a dealer that buys older EDM (all brands) and refurb them and give a warranty and training. If you would like some info on them or have any questions send me a PM and i will be happy to talk about it.  |
