    Mits MV4800 Water Leak from Lube Hose

    We have a Mitsubishi MV4800 WEDM that has been leaking from the left side of the machine. The water is coming out of the small hose that normally drains the bad lube oil or excess oil or whatever drains into the bigger of the two jugs that sit in there. The water will start leaking from the hose...

    Multiple Workpieces on Mits MV4800

    Hey all, We have a Mitsubishi MV4800 WEDM that I am trying to set multiple work pieces up on, one in the lower left corner and another in the lower right corner. This is my first time attempting multiple work pieces and after some research and brushing up on how G54-G59 works I thought I had...

    Mitsubishi MV4800 Annealing Rollers won't close

    I've just started having problems with the wire not cutting properly on our MV4800 WEDM, after checking some things I've narrowed it down to the annealing pinch rollers towards the top of the machine not closing fully. When I go to cut the wire it'll attempt to pinch the wire but it won't close...

    Hole Popping with Copper Tubes

    Hey all, I have a steel block that I need to do some hole popping and then wiring on. There are four ejector blades on this block with a width of .062 thou and run 1.5 in. deep, ideally I'd run a .040 thou(1mm) brass electrode for hole popping but that'd only leave me with a .011 thou a side...

    Bottom of the Work Tank Durability

    Hey all, I was cutting a 6 x 8.25 x 4 Beryllium block out in our Mits WEDM, long story short the game plan I had to remove this block from the machine didn't go to plan and it fell hard to the bottom of the work tank, from visual inspection nothing seems damaged and I had moved the bottom head...

    Mitsubishi Wire Alignment Device Troubles

    Hey all, Lately when doing a wire alignment on our MV4800 the top green light will not light up when the wire is touching it causing the wire alignment to fail. Usually messing with how the cord is resting and clearing everything off the table of the machine will fix the problem after about 5...

    Hole Popper leaves bad pitting around the Hole

    Hey all, So recently I've been playing around with our hole popper in the shop getting some experience with it. I've just been mainly removing taps and stuck drill bits from holes and occasionally putting in new start holes if I don't like how a block is setup for wire. Long story short...

    Wire Differences

    Hey all, So we are currently getting a PM done on our two MV4800 Wires and our service tech is pretty adamant about the benefits of using Mitsubishis' official wire. We run un-coated .012 FireWire and always have since I started here. From using it I really have no complaints about it though I...

    Wire won't Thread out of Pipe End

    Hey all, We have MV4800 WEDM that is having a problem threading that I've never encountered before. The wire threads on its own past all the diamond guides, past the lower roller, and into the long tube that takes it back to the wire chopper. However, just before it can get out of that tube and...

    My first PM on Mits Machines, Anything to do before hand?

    Hey all, We have 2 MV4800 WEDMs that are long overdue for a PM service. I haven't been doing Wire all that long(8-9 months) and I decided it was probably time for a PM as our last records show that they haven't been serviced for almost 2 years. I've done an egregious amount of self service to...

    Wiring Tapered Holes Results in a Bunch of Tiny Flats

    Hey all, I've recently had to wire a new taper into a Sprue bushing. The taper came out as close to perfect as it can be however the actual circle on the inside of the sprue that I wired wasn't, instead of it being a smooth round circle it consisted of a crap ton of tiny flats that made up the...

    Retract Moves, What do they do?

    Hey all, So recently I made an error while doing a job, just some simple oval pockets that I was cutting to size. Came in this morning to a unhappy boss asking why there were little wire marks cutting into the part at the start and end of where I had my cutoff. After I did some digging through...

    Tall and Angled Parts Tips

    Hey all, I've just been given a heads up that in the near future I am going to be cutting some lifter pockets(unfortunately I don't know all the specifics of the job yet). From what I do know about these and what our previous wire guy has on his computer in the most extreme cases it'll be about...

    ESPRIT WEDM Help

    Hey everyone, I've been having problems lately with my ESPRIT. I'm wiring out pin holes that need to have a nice fit in some cavity blocks. I use SolidWire on ESPRIT to create the operations for my Mits machines. Recently however I've been having a reoccurring issue on both my MV4800 wires...

    Differences in Workpiece Thickness

    Hey Everyone, So today I started cutting parting line straps. However while I was tooling them out on ESPRIT and putting in the parameters for the cut it struck me that I wouldn't be cutting the same thickness the entire time due to some pre-existing holes. Thankfully these don't need to be all...

    M20 Macro

    Hey everyone, I have a Mits MV4800 WEDM. This machine likes to be fussy about when it wants to insert the wire by itself. Some days it'll thread by itself just fine at any Z height, and other days it'll rarely thread below a specific Z height. This time around it doesn't seem to want to thread...

    Off by a Mile

    I'm currently attempting to wire out some ID inserts, 6 to be exact. I wired out the first one and felt like it went smooth, sent it over to our toolmaker to check dimensions and such and to my surprise I somehow managed to mess it up pretty bad. The insert is 3.181 in. long with a hole in the...

    Mits Maintenance Help/Tips

    Hey there everyone, this is a two part question. First some general knowledge, I've just started WEDM about two months and it's my first job in the manufacturing industry so I'm very inexperienced with just about everything(so go easy on me:D). I took over this job after our last WEDM guy was...
