    OT - Questions to ask at an interview (for a machine shop)

    Unfortunately I have come to the conclusion I need to leave the company I work for and find someone different. I am in process of getting an interview for a place lined up, but I'm trying to think of questions to ask the interviewer. The position, to my understanding, is a quality inspection...

    What's in your toolbox? - EDM Edition

    Morning folks! I've come into possession of my own personal toolbox, and I need things to fill it with! The shop I work for supplies most of the equipment needed for setups and tear downs, but it never hurts to have personal items just in case, I figure. What are some good tools to keep on...

    Getting flux and other gunk off PCD - What is your method?

    This one goes out to all the synthetic diamond cutters. When you have gunk on the tables of your PCD, what do you use to get it off? Generally Xylomate works for us, and harder substances we use old Papermate Union erasers. Sadly, you can't really *find* those erasers anymore, so we're looking...

    Where do you buy your wire?

    Morning folks! I'm curious, what brand of wires do you all use, and where do you purchase them from? I'm not necessarily dissatisfied with our wire, but I'm always on the hunt for something better. Any leads on soft to half hard zinc coated wire (.008") would be a bonus! We currently use...

    OT - Mild rant about the price of used cars, and where to even find them?

    My partner is in the market for a used car. Where do you look for them, aside from dealership websites? With the chip shortage cars seem hard to come by - let alone for any sort of reasonable price - but the repairs on his vehicle are starting to total over its worth, and he's ready for...

    Routine Maintenance of a Wire EDM Machine

    So in my shop I have a feeling I'm soon going to become very responsible for the upkeep of several Fanuc Wire EDMs. I know to move the electrodes, replace the bearings in the heads, and replace the guides occasionally. And, of course, keep the tank clean. I'm also going to become privy to when...

    Non-Conductive additive to prevent cobalt leaching?

    So I'm doing some research on cobalt leaching, and specifically ways to prevent it. I've found some options to do so, but it appears they are all conductive materials, so I would not be able to add them to a dielectric fluid in an EDM machine. (It appears they are more for, say, ultrasonic...

    AC vs DC current?

    Sorry for making so many posts lately, I just have so many questions, and in this case both google and books available are falling short in the answer. I am mainly burning tungsten carbide, PCD, and some steel (though I am unaware of what type of steel) as I make cutting tools. My mentor has...

    Simple Question: Stable Reduction Value for Tech Optimization? (WEDM)

    So, I'm going to start attempting to optimize my cutting speed using a job that takes an infamously long time to cut, but is generally easy to re-thread broken wire. Sources I've found say that the first step to increasing cut time is to reduce the off-time, then the servo gap voltage, or even...

    Newbie looking for advice - WEDM

    So I'm relatively new to wire EDM, having been training in my position for less than 6 months. My shop is a precision machining, and I EDM PDC, steel, and carbide. We have on hand currently a Charmilles Robofil 200, a Fanuc Robocut a-1c, a Fanuc Robocut a-0c, a Fanuc Robocut a-C600iA, and two...
