Wanted to pick all your brains on Wire EDMing graphite. Cutting on a Robocut with AI settings and do not have presets for graphite. Normally use tool steel setting(A2) and tweak the on/off, speed and SV. Get a lot of wire breaks even if I soak the graphite over night. Any suggestions on power settings or setup techniques. Mainly cut smaller thickness from 1/2" to 1".

Belmont SY2535 EDM Drill
Ok running a Belmont SY2535 EDM Drill. The recommended settings, and all trial adjustments, for a 2.5mm electrode cutting 6061 aluminum to a thru depth at 9 inches, are apparently not applicable or is this just to deep for an electrode? any suggestions on the settings?

Transformer oil as dielectric
The guy that does my electrical repair suggests that transformer oil would work as dielectric. Sure don't want to get into a bacon grease as cutting oil discussion
but there is a local supplier and sure would save money and bother if it would work.

Wire EDM costs?
I was wondering what is typical production pricing for wire EDM cuts? Per square inch or square mm?
Came accross some ch**nese insert holders where the slotting is evidently done with wire EDM cutting.
When the total price for the insert holder is about 4 usd the EDM wire cut has to be dirt cheap. I would have imagined that simple slotting like in these would be done with slotting saw but apparently wire EDM is cost-effective alternative :eek: ( seen one with slug still in place...)
I'd say that there is ½ to 1 square inch to cut these:

Please send contact info.
I will be needing flat washers of carbon steel, 2 3/4 OD", 1/2" ID thickness .075" to .2"
Concentric with good 1/2" bore to turn on axle... ( Can we hold +.002" ?? )
Just a couple hundred to start.
Still in material selection.

Graphite qyestion
looking for a graphite that has the least amount of flex. Working with tight tolerances the thickness is .050 x .360 and the depth is 1.400. The readings vary from the bottom start at .000 to the top of electrode.006 currently using CP3000 graphite. Any help would be appreciated.

Robofil 310 screen help
Hi,
I have a 93' charmilles robofil 310 that I recently purchased. I have brand new disk A and B. My problem is after disk A loads I can only seem to get the Graph screen to appear on my screen. When I try to switch to Prep, EXE, or Info my screen starts flashing and says this image cannot be displayed. The green indication light on the monitor starts flashing from amber to green similar to when a computer loses communication with the screen. I can always go to the Graph screen without a problem. I am using a regular computer monitor. I have talked to tech support and the individual told me I need a new screen or monitor from them because my monitor may not be compatible with their software. ($2200). I don't have a problem buying a new screen it did seem like he jumped to that conclusion really quick. I am unfamiliar with this machine and was just looking for some more opinions.
Thanks
Joe

Burn depth control question
First off let me say thank you again to Marcus and Nobby for the help with the rotary dressing a couple of months ago. :D:D
I have a new question about depth control and maybe finding a better approach to what I am trying to do.
I am burning a straight sub-gate that is .550 +\- deep. (Some tools are a bit less, some are as much as .200 more.) The gate itself is .015 dia. with a .002 land between the cavity and the sub-runner or runner drop.
The problem I'm having is controlling the depth of the runner drop so that the .002 land does not come out too long or too short as either of those conditions affect the gate vestige on the part. If the land is too long the vestige is too big from the first shot and if the land is too short the gate will wear oversize in short order which also creates a large vestige.

Currently I am burning the gate from the cavity side as deep as I can(.150+/-). Then I am turning the part over and burning the runner drop from the runner side. I am using one rough electrode to get as much material out as I can and to connect the gate with the runner drop more sooner than later so I can then use the gate to flush from the bottom on the finish burn.
I'm using Copper-Tungsten for both gate and runner electrodes and the work material is CPM 10V at 62 Rc. IonoPlus dielectric.
The rotary dressing solved my location issues as far as keeping the drop and gate concentric but the depth issue is kicking our A!%.
I've tried reaching in with a .016 carbide pin from the runner side to measure the depth but I'm not getting consistent enough results to have much faith in that approach.

I am needing info on anyone who could come in and train us. The Sodick rep has the machine hooked up and he ran it through a sample cut and all works properly. I am located in Northeastern Indiana.

Cutting multiple stacked sheets at the same time
Hello,
My company is interested in using a Wire EDM cutting process, but we have no experience in this area.
We are interested in stacking a number of thin silicon steel sheets and cutting them with a Wire EDM process. If we try to cut multiple sheets at once, will the Wire EDM process melt the metal and fuse the sheets together as it cuts?
Any comments on the possibility of the Wire EDM melting material as it cuts would be a great help.
Thank you,
Eddie

Aftermarket Filterfilter units
Currently on a 25 - 26 day nonstop run of carbide parts. I'm gonna have a hell of a time getting it cleaned afterwards....
I was wondering if anyone had tried separate self contained filter units for their wire EDM?
If so,
Was the unit worth the investment?
I was thinking of the pricing Ebbco units to clean the work tank as the machine was cutting.
Has anyone here used this manufacture?

Mitsubishi FA10S edge find
We bought a used Mitsubishi FA10S EDM. We have the manuals and a guy who ran Mitsubishis years ago. We're making parts but have a question about edge finding. When we edge find we have to manually input the wire radius to set the zero. The manual even states in the Basic operations section that you have to account for the radius. Is this right? Seems like a simple calculation for the machine to make. We have the wire diameter set in the Maintenance pages in several places.
Can the machine do it on its own? What are we missing?
Thanks
Chris
