Charmilles FO 350 SP Problems with drop tank.

June 21, 2016, 11:27 am

We purchased a Charmilles FO 350 SP from a broker. Well its fine but 1 problem. The Drop Tank at electrode change or cavity change does not return to the correct height and keep burning. The tank stays exactly 1" below the specified height of return and will not burn.
In order for us to keep burning we must hit the red cycle stop button and then hit the green cycle start button and then the tank rises 1" inch to correct height and it will start burning. We have to go thru this every electrode change or cavity change.
Has anyone gone thru this situation and what was the cure?
This machine is a 2012 and has low hrs.
We have called Charmilles and they are no help or want to help us. We have 2 other Charmilles on the floor. Our sales rep in our area put us onto this machine and is trying to get Charmilles to give assistance but its falling on deaf ears.

Does anyone have experience with Taiwanese EDM ACCUTEX? How good is this machine? I would need it to produce spare parts such as knifes, punches, and other parts for my dies. What are the advantages and disadvantageous of this machine?

I make jewelry dies. I have been making them for many years, I carve them by hand and with manual machines. I have started making my masters from copper and silver and having them sunk by an edm shop down the street. They are using an charmilles edm from the early seventies. I would like to buy one any idea what is a good one for this kind of work.

agiecut 170 hss generator power supply

Something shorted on the power supply board and killed the fuse. With all wires disconnected I have a closed circuit at the 24v pins with an ohm meter. So I am guessing a new fuse will not fix the problem. This is a 150w 24v power supply. Is it safe to replace it with a "same spec" power supply or should I buy it from agie. The one from Agie is 1700 bucks and the one from DigiKey is 78 bucks. Your thoughts are appreciated.
Thanks Phil

Good day EDM'ers

Does anyone know the backlash parameter numbers on a Fanuc 16-W controller and how to get to them?

I tried 9999 PG Up but don't see anything there.

Would appreciate any assistance.

Agie HSS 150 wire sensor problem

We are getting an error (code 420) which is associated with the wire sensor located at the top of the machine which looks to be a small solenoid which makes contact with the metal wire pulley. Can anyone tell me what this sensor is actually doing? After looking at the machine and the description in the manual I think it is measuring conductivity from that pulley to the carbide pad in the upper head assembly which supplies power to the wire when cutting. It is supposed to draw the wire back up into the head after a break/before threading and it isn't doing that. What I'm guessing is that once the wire is drawn up above that carbide contact that there is no longer conductivity between it and the metal pulley and the machine knows to stop. However, that is all an assumption, if anyone knows for sure it would be much appreciated.

Agiecharmilles CUT E 350 vs Cut 200 Sp

Once again I need some expert advice. I have finally narrowed my choice between these two machines: Agiecharmilles CUTE350 vs Cut200Sp. The price difference between them is 14 000 EUR or 15 500USD. In my region most companies have old EDM machines, so I am thinking with a better machine I have a better possibility to get extra orders from outside.

So is there a point to pay extra for CUT200Sp? Is the Cut200Sp much better than CutE350?

Thanks in advance.

Polishing/Cleaning an EDM surface

Hi All,
I am currently working on a job that requires an 18 VDI finish. I have a slight issue with the finish. there are multiple "hotspots" or "wear marks" on the EDM'd surfaces. The EDM surfaces cannot be polished, but the black marks left by the copper impregnated electrodes are raising concern in the tool making area. i explained to them that it poses no threat to the quality or functionality of the cavities, but they still want the marks cleaned up. I tried lightly scrubbing at the marks with a q-tip and acetone, q-tips and wd40, and q-tips and acidic toilet bowl cleaner.Nothing fully removed the spots. does anyone have any suggestions that do not require polish? thank you in advance

Anyone using a Fanuc Robocut A-0A machine?

I have a chance to do some trading for one of these but I know nothing at all about wire EDM. I know it was built in 1993 and doesn't have auto thread. It is a A04B I think. The man that has it says it needs new guides? I saw it under power yesterday but they only had one guy who could run it and he quit so I didn't see any programs run or anything.

We would use it mainly to repaid die sections and maybe make some new ones. Nothing real fancy or really in need some something fast. If I trade I'd have about $900 in it but I guess what I need to know is how easy are they to learn to program and are parts and support available still?

I appreciate any information or advice as I know very little about EDM

Mitsubishi DWC -90H Alarm Code # 625 Interlock of positioning (please help)

Hello all. I went out to the shop this morning to start the day with a wire alignment. When I attempted this, I got this alarm: 625 INTER LOCK OF POSITIONING. When I look in the book, the definition is this: Positioning is in progress, so no other operation is allowed...


What seems to be implied is that something else like center finding, jogging, edge finding etc has already been initiated..

I cannot find anything going on behind the scenes. I have also tried reset, shutting machine down etc...


Anyone ever had this happen? any suggestions? Please help

Thanks

Water conductivity - Do you ever change the standard "tech" value?

July 14, 2016, 8:11 pm
$

Guys, just trying to find out if any of you ever mess with the conductivity values that come with the factory techs?

Background:

I am a purely "bandsaw", production guy, no skimming and no splitting tenths.
Materials are virtually never any steel cutting, 99% is SS, Nickel, TI or a very small amount of AL.

On my Brothers, the default conductivity is always in the low 30us range for all materials, except for AL, which is in the teens.
Got used to it, never bothered to change to a lower setting. As it was/is for the last 15+ years, my resin consumption is less than negligible.
The best way to give you an idea about the resin usage is that it's under $.02/hour, or give and take 2500 cutting hours for a 5lbs? bottle.

Now on my new machine ( 18 months old), the standard technologies typically call for a conductivity in the mid teens ( usually 13-16 - ish )
When I've started running it and after exhausting the large ( 30 lbs?) bottle in about 200 hours 3 times, I started to monkey with the standard tech and
went up to the Brother's level of 30us.
Well, the end result is now the very same as with the Brothers. Approx. $.02-.04/hour.
I have not noticed any speed reduction, nor deterioration of any of the machine components.
Obviously, noone can rust Inco625, 718 or TI, but I have absolutely no corrosion on any of my tooling either, which are typically 17-4 or 303SS, so
the higher conductivity has no effect on my finished parts that I'd need to worry about.
Dimension variations are also of no concern, 1st cuts are always within .0005 after the offset is dialed in.

So basically I ( within my needs and confines ), see no detrimental effects of the increased water conductivity.

Can anyone perhaps shed some light on what - if anything - I might be missing as far as the downside is concerned?
Cost is of no concern. I use only virgin resin and I typically fill my own. The price of a box ( barrel) of virgin resin is reasonable, and would be even with the higher usage.
Downtime is also not an issue, I do have spares for each machine so bottle changeover is under 2 mins.

Thank You

New to burning tapers, wanted some tips on what works best. Currently using 900n wire, heard 500n works better, tried it but wire kept breaking when it came into contact with the steel, not sure if its a bad e-pack setting or bad brand of wire. Currently has 8mm cups and the most ill be cutting is 15 deg. Any tips on programming or settings would be great, Thanks

Mits Epac offset value/code question

July 20, 2016, 6:49 pm
$

I have been trying to understand the Epac's and their settings more closely in order to maximize their abilities/capabilities and I came across that the H offset has the options of 1,2,3 etc. depending on the pass. My programmer uses H1=.00__ for all passes rough or skim. How much of an effect on the cut would that make? Does it even matter the H1 or H2, H3 or is the actual value of .0084 for example for the offset what is important? From what I interpreted, the H1,H2... takes in consideration wire size, over burn based on power of Epac and then the offset value (.0084) and comes up with how much to offset. Don't know if that is correct or not but would love any input on this as well as adjusting stabilizer settings to avoid wire breakage and improve speed.

Also has any one used the "alternative" EPAC settings like for .010 brass wire EPAC#'s example #1309, 1308, 1307, 1300, 1306 for different situations of poor flushing etc.? Were they more effective than the normal rough cut 1301 setting?
I am working with D2 steel if this helps.
Thank you,
Toni
